Introduction: RC Sailboat

RC Sailboat

This instructable was created in fulfillment of the project requirement of the Makecourse at the University of South Florida (www.makecourse.com).

My passion for sailing is what inspired me to make an RC sailboat for my project. I wanted control the main aspects of sailing: raising the sails, trimming the sails and steering, in order to make it as authentic as possible but to also make it easy to sail. I based the design around a ketch style sailboat but modified it to incorporate the Makecourse required box.

Step 1: Components

Components

Below is a list of the material used to construct the RC sailboat, most of the items can be sourced on Amazon or a hobby website like Hobby King .

Electronic Components

  • Qty. 1 - Arduino Uno
  • Qty. 1 - Arduino Nano
  • Qty. 1 set - RF Transceivers .
  • Qty. 4 - Continuous rotation servos
  • Qty. 1 - 180 Degree metal gear servo
  • Qty. 2 - XY Dual axis joystick
  • Qty. 1 - LiFePo4 Battery
  • Qty. 1 - AA Battery pack (controller power)
  • Qty. 2 - PCB Prototype boards (on board servo power)
  • Qty.1 - 9v Battery & plug (on board arduino power)

Hull Material

  • Qty. 1 - 4'x4' 5mm sanded plywood
  • Qty. 1 pack - Maple veneer (would have used ash but local wood shop didn't have it)
  • Qty. 1 - 1/2"x3' wood dowel
  • Qty. 1 - 3/8"x3' wood dowel
  • Qty. 1 bottle - Titebond III Ultimate wood glue
  • Qty. 1 bottle - Superglue
  • Soldering Iron
  • Wire cutter
  • Sandpaper/Dremel
  • Needle Nose Pliers
  • Screwdriver
  • Painters Tape
  • Fishing Line or Equivalent

Step 2: Design

Design

The design was based off of a ketch style sailboat which was scaled and modified to incorporate the Makecouse required box. I took technical drawings that were found online and modeled a skin on spar design with a 2" spar spacing. I chose a skin on spar design because it would be the lightest, provide mounting locations for servos and the easiest to manufacture with my resources.

I sourced continuous rotation servos for the sail halyards (lines to raise the sail) and sail trim which allowed me to have an infinite range of sail heights and trim while also providing enough torque to accomplish the tasks. The rudder servo is a 180 degree metal gear servo because it has exceptional torque and won't strip out like the plastic gear servos. I attached a 3D printed spool to each of the continuous rotation servos so I could wrap line around them to control the halyards and sail trim.

I originally planned to attach a lead keel for counter balance put as of right now it is fairly heavy and it may add to much weight. One design flaw I found after assembling the sailboat was that the line used to control the sail trim will jump off the servo spool unless there is constant tension on the line. I would suggest redesigning it so there is a direct or mechanical linkage controlling the sail trim.

All of the Solidworks 3D files are also attached.

Attachments

Step 3: program.

Program

I used the Arduino IDE software to write both the transmitter program and receiver program. The majority of the program was focused around the nRF24L0I RF transceivers which I found most of the necessary code on the numerous helpful forums .

For the transmitter code I assigned the joystick inputs to array which was then sent as one packet via the transceiver. For the receiver code I took the array of joystick inputs and assigned one axis of one joystick to the rudder servo and one axis of the other joystick to the sail trim servos. The push buttons of each joystick were used to control the sail halyards.

A few issues I found while programming was that the center of the continuous rotation servos was not exactly 90 degrees. The centers were off by approximately one degree so I had to adjust and map accordingly.

The two Arduino program sketches are attached.

Step 4: Fabrication (Hull)

Fabrication (Hull)

This was my first time building a sailboat of this complexity so it didn't turn out perfect but I learned a lot along the way.

After I carefully removed the laser cut pieces from the work piece I sanded down any rough edges and began by gluing together the appropriate sets of spars making sure to clamp the pieces per the glue directions. After I had spar sets glued together I clamped them to a make shift jig where I could file the notches to accept the spine. Once the glue on the spine had set I began sanding the spine and the spars to achieve a smooth curve along the entire boat so that the skin would lay properly without any nasty bends.

Now that the skeleton of the sailboat was finished I focused on skinning it. I took a ~4" strip of veneer and traced the profile of the boat on it. I then cut this profile out, over sizing it quite a bit at first and then slowly cutting away material until I achieved the desired fit. I continued this process working my way from the keel to the deck.

Once I had my skin pieces trimmed I began gluing them to the skeleton by clamping and taping them where I could. I used two bags of dirt, rice would have been better, to apply pressure so that the skin stayed contoured to the spars while the glue dried. Again, I started at the keel and worked my way up to the deck. When I got to the last piece where the deck was I had to prop up the sailboat so that the veneer would clear the jig.

A few things I learned that would be helpful when building, use more and smaller strips of veneer to skin the boat, they're easier to work with. I tried only using two pieces of veneer to cover each side but they did not want to contour to the spars, so I ended up using three pieces. A big help when trying to glue the skin pieces to the spars is to clamp them to the skeleton first; once you have it where you want it spray the skin piece with glass cleaner which will soften the wood. When it dries after a few minutes remove the clamps and glue the now formed piece to the skeleton reducing the panic and effort required when the glue is tacking up. Be careful not to wait too long though because the wood will eventually flatten to its original state if left sitting.

Step 5: Fabrication (Electronics)

Fabrication (Electronics)

I started out by prototyping both the transmitter and receiver circuits on a breadboard. I did this to make changes and diagnosing easier. Once I had both circuits completely programmed and working properly I moved on to making a shield for each circuit.

By simplifying the circuit it freed up more room and made the system look much cleaner. I started by laying out the locations of my components making sure to eliminate wiring jumping as much as possible. Once I had the components routed on the prototype PCB board I began soldering the appropriate headers for the pins I would be using on the Arduino. When all of the headers were soldered I began connecting the Arduino input and output pins to the correct component and power pins. Since this was a prototyping PCB board I used solid wire to bridge the gaps. As I went along I checked continuity between adjacent pins to make sure nothing was going to short. After I finished a board I would power the board with just the Arduino to double check that I was receiving the proper voltages. Lastly, I completely assembled both circuits and made sure everything was working properly.

Step 6: Assembly

Assembly

For final assembly I started with assembling both masts minus the sails, since the the bolts to hold the mast to the spars were the lowest thing in the sailboat. After that I bolted the rudder and servos to the spars starting from the outside working my way in, so the rudder and main sail halyard followed by the mizzen sail trim servo. I then bolted the two servos inside the required Makecourse box. I then attached the required box to the spars using screws.

From here I plugged in all of the components to the shield and Arduino to make sure everything was functional. The rudder was attached to the servo using two pieces of solid wire, the sails were then attached to the mast and boom using paper clips and fishing line. I used fishing line routed around the servo, up through the paper clips and over the mast topper. Note that looped the fishing line around the sail halyard spools and back up to where I connected the line to the head of the sail. This allowed me to lower the sails using the same halyard servos.

That was for the sailboat assembly, for the controller, I zip tied the AA battery pack to the back of the controller plate. The PCB board and joysticks were just screwed to the controller plate. It is a very crude but functional controller.

Some of the difficulties I ran into include: PCB board to big for Arduino location, tight space to run the fishing line and the sail trim system was poorly designed. For the PCB shield in the sailboat, the Arduino was mounted in the corner of the required box which didn't leave enough room for the shield, so I cut off the corner of the PCB shield. For the tight spaces needle nose pliers are very useful but I would revise the design to make it bigger so assembly would be easier. As for the sail trim system, what I found was that when using fishing line you had to keep constant tension on the line otherwise it would unravel. Keeping constant tension is almost impossible while sailing because of wind strength and direction changes. I would revise the system to use a mechanical connection whether it be a direct connection to the boom or a linkage system.

Overall, the final assembly was much easier than I thought considering the tight spaces.

Step 7: Go Sailing!

Go enjoy your new RC sailboat, preferably on a small lake when the winds are light otherwise you'll be fishing it off the bottom!

Sailing an RC sailboat is fun, but it takes some practice before you get good at it. I certainly needed it when I started! If you want to take your interest in RC model boats to another level, then you should consider learning how to sail an RC sailboat.

However, learning how to sail RC sailboats requires patience and perseverance. There are several things that you need to master before you can begin sailing. This article will teach you how to sail a radio-controlled sailboat.

Read on below to discover tips that will avoid failure in learning how to sail model sailboats, that apply to all size boats.

Step by step Instructions

How does a yacht sail, how are the sails and rudder of an rc sailboat moved, moving forward in a straight line, sailing into the wind, sailing away from the wind, final thoughts.

First, here’s a summary step by step approach to learning how to sail an RC sailboat:

  • Consider joining a local club ( USA UK ) where you’ll find lots of helpful RC sailors and RC sailing events that will help you learn. You may even be tempted to get into RC sailboat racing. 
  • In any event, choose a day with a gentle, consistent, light wind, preferably with the wind direction towards you, just in case you lose control of your boat.
  • Find a medium-sized lake or pond, and avoid rivers or the sea, where there may be strong undercurrents. A local club will have a safe sailing area. Look out for areas that may have weeds or reeds, or shallows that could strand your boat. Remember to factor in the depth of the keel, which, on most model sailing boats, is significant. 
  • Check you are able to sail in your chosen area – ie no prohibitions – and keep clear of swimmers, people fishing, full sized boat traffic, and wildlife.
  • Avoid days when it’s busy in your sailing area with other modelers until your sailing skills are such that you can feel confident.
  • Set up your RC sailboat on its stand, and check the rigging is as it should be according to the boat’s instructions. Ensure you have brought the boat battery pack charger, the batteries are charged, and you have spare AA batteries for transmitter. Turn on the transmitter, and test that the rudder control and sail servos are all working properly.
  • Ensure you understand the basics of sailing, set out below, before launching your RC sailboat. Keep a keen eye on how your boat reacts to the wind, and be ready to react in turn by altering the sail angle to maintain the boat speed as far as possible.

The first thing you’ll need to know is how does a yacht sail? An rc sailboat sails just like a full size yacht. The wind energy pushes against the sails and flows over them, creating a difference in wind pressure on each side of the sail, which is translated to forward movement by the keel of the boat. Without the keel, the boat would be pushed in the direction of the wind.

To keep the yacht moving forward, the sail angle to the wind is adjusted depending on the position of the boat. Paradoxically, a sailing boat can sail into the wind, as well as with the wind. The only direction that can’t be sailed is with the wind directly in front.

The direction of the boat is adjusted by the rudder, which is at the back of the boat.

The following diagram shows the sail angles at different points of the wind:

how to make rc sailboat sails

As a beginner RC sailing boat helmsman, many of these terms will be confusing to you, but they will soon become familiar.

The controls of an RC boat are explained in more detail in t his article , but basically, the hull (body) of the boat contains batteries that power servos which in turn move the rudder, the main sail, and the fore sail (the “jib”). The servos are controlled by a receiver, that takes commands from the RC transmitter which you hold in your hand. Here’s a short video that explains the transmitter controls:

How to sail an RC sailing boat

First, the basic skills. With the boat in the water, start with the wind half way between the front (bow) of the boat, and the side (beam). Keeping the rudder straight, trim (move) the sails so that they are close to the hull (close hauled) and the boat should move forward. If the wind is gusty, or very strong, move your transmitter control to let out the sails, spilling the wind, to keep the boat from keeling over.

If you’re sailing into the general wind direction, you’ll need to learn to “tack”, which involves turning the boat from a position where the wind is coming on one side of the bow, through the head-on wind, to end with the wind on its other side. This is achieved by moving the rudder to turn the yacht, whilst changing the angle of the sails to the wind – see the diagram above.

So the boat moves forward via a zig zag course.

As the boat turns into the wind, it slows, so this maneuver should be completed as quickly as possible, otherwise, the boat could get stuck with the sails flapping – this is called being “in irons”.

If the direction you wish to sail in means the wind is behind the boat, it is called running before the wind. In this case, turning the boat involves “jibing”, which is the opposite of tacking.

To change direction whilst running with the wind, move the rudder so the wind goes around the back (stern) of the boat and haul the sails in. As the boat comes round, the wind will move from one side of the sails to the other.

If this is not done smoothly, it could cause the sails to violently move in the opposite direction, possibly causing damage and maybe even capsizing the boat.

So those are the basics of learning how to sail an RC sailboat. As I’ve said above, the best way to refine your skills is to get out on the water and practice.

if you have any interest in remote control sailing but aren’t sure where to begin, use the step-by-step guide above to learn how to sail an RC sailboat. Once you’ve mastered the basics, you can move on to the exciting world of racing sailboats.

If you’re still considering your first RC beginner sailboat, take a look at our article on beginner RC sailboats , or for the more adventurous, consider building your own RC sailboat from a kit. More about that here .

While not specifically for models this program the ' SailCut CAD ' program allows plotting of panels etc for sails.  Its discussions and examples are very useful.  This is a free download but does require some computer knowledge to set up

An excellent article by Paul Bogataj on " How do sails work " - essential reading!

In all of this literature there appears to be two common themes

1. To achieve a truly efficient sail it must be constructed with separate panels with built in shape or curvature.

2. Some means has to be used to hold the edges of the panels to the correct shape while joining them.

How Do You Sail An RC Sailboat? (11 Essential Steps!)

To make the most of your time on the water, it’s crucial to understand the art of navigation. We’ll focus on the essential aspects of navigating an RC sailboat, from selecting the right location to mastering advanced maneuvers.

Push the rudder joystick left and right to steer the RC sailboat. Open and close the sails to tighten and loosen the sails, this will increase or decrease your speed. If there are strong winds, tighten the sails so that they don’t flop around. Partially close the sails in low wind conditions.

how-do-you-sail-an-RC-sailboat

It’s all about working with the wind and keeping an eye on the sails to make sure that they are catching the wind from the correct direction. Steering the boat required you to position the rudder and sails correctly.

So let’s go into every aspect of sailing an RC sailboat along with a whole lot of advice.

Steps For Sailing An RC Sailboat

  • Check the rigging for any damage or tangled lines. Confirm everything is in good condition and properly rigged, like sails, lines, and other rigging hardware.
  • Check that your boat’s weight distribution is correct for optimal performance. The boat should be level in the water with the hull must be parallel with the surface. An off-balance boat can cause slower speeds and unwanted turning. (Learn more about how fast RC boats go ).
  • Adjust the sails according to the wind conditions. Beginners should start with smaller sails in light winds while more experienced people make use of larger sails as their skills improve.
  • Make sure the keel and rudder are attached and properly aligned. The keel provides stability and the rudder controls the boat’s direction.
  • Switch your transmitter on and check that it’s set to the correct frequency or channel for your boat. If you’re keen on upgrading your sailboat’s engine for a smoother ride, you might be interested in exploring some of the best RC gas boat engines out there.
  • Power up your RC sailboat by connecting the battery pack. (Some boats have power switches, while others may turn on automatically when connected).
  • Before launching the boat, hold it in the air and test the controls of your transmitter to ensure everything is working correctly. Normally, you’ll have controls for the rudder on the right stick and sails on the left. Some high-end models even have a throttle connected to a tiny motor for launching and docking the boat.
  • Gently place your boat in the water and make sure the sails are positioned so that the wind can fill them up. Release the boat and let the sails catch the wind.
  • Use the rudder control on your transmitter to steer the boat by pushing the rudder stick left and right to steer the boat in either direction. It can take a few seconds for the sailboat to react to your controls so adjust the controller sticks gently.
  • Push the sail stick up to adjust the sails and catch the wind. Experiment to find the best sail angle for your boat’s performance.
  • If you have a throttle, use it to get the boat out deeper into the water for the wind to open the sails. Take it slow when you open the sails if you’re still learning. Once you’ve gotten familiar with the controls, you can increase that throttle on launch and during docking.

By the way, have you ever wondered how to size an RC boat motor ? Choosing the right motor size can significantly improve your boat’s performance, especially if you’re looking to get into more competitive sailing.

Sailing an RC boat takes practice. Pay attention to how your boat responds to wind and control inputs. Experiment with different sail and rudder positions to get the most out of your boat.

When you’re finished sailing, bring your boat back to shore while avoiding running into the ground or colliding with obstacles. Disconnect the boat’s battery pack and turn the transmitter off.

Just starting out with RC sailboats? Don’t get overwhelmed! We’ve rounded up the best beginner-friendly RC sailboat models that are easy to operate.

Select The Right Location

Sail on water like lakes or calm ponds to ensure to avoid interruptions while you’re sailing. Avoid busy, crowded locations with heavy boat traffic to avoid bumpy and difficult-to-navigate waters.

Tranquil waters provide a peaceful backdrop for you to focus on refining your sailing skills and enjoying the beauty of RC sailing.

Crowded areas increase the risk of collisions, making it challenging to maneuver your RC sailboat effectively. To maximize your enjoyment and safety, prioritize the selection of the right location. This is the best way to do things while you’re learning. Then later on once you’ve gained enough skill to sail around other boats and obstacles, you can do so with confidence.

Assessing Wind Conditions

The wind is what’s going to move you around on the water so an understanding the its direction and strength will help you plan your sailing route effectively and avoid problems.

Adjusting the angle of your sails and reading wind shifts will help you navigate smoothly.

Note the strength of the wind, whether it’s gentle and steady or strong and gusty so that you make appropriate sail adjustments. This will enable you to sail safely, avoiding collisions with obstacles or other boats.

You can tell that the sails aren’t catching the wind by checking if they’re flopping around like flags. If the wind is blowing strong and the sails aren’t catching it, you need to turn the sails slightly to fill them up with air.

You need to start learning about how the wind interacts with your boat to assist you in charting an efficient sailing route.

Preparing Your RC Sailboat

Carefully assemble your RC sailboat according to the manufacturer’s instructions. Ensure all components are securely in place, and check for any loose or damaged parts before launching.

Proper preparation is the foundation of a successful RC sailboat journey. It ensures that your sailboat is in optimal condition and minimizes the risk of in-water mishaps.

Of course, things don’t always go as planned. If you’re facing issues with your boat not responding, it might be good to know why your RC boat is not working . A quick troubleshoot could save your sailing day.

Sail Adjustments

Correctly adjusting the mainsail is essential for maximizing your sailboat’s performance. It directly impacts how your sailboat responds to the wind and steers through the water.

I’ll go over advanced techniques in a moment, but for now, you should focus on making small adjustments to the sails so that you can get a feel of how they interact with the wind.

Sail adjustments are like the controls of your RC sailboat, allowing you to fine-tune its behavior to your commands.

By the way, if you’re new to this whole RC sailing thing, it’s crucial to know what you need for an RC boat . This guide will ensure you’re not missing out on any key items before you hit the waters.

Safety Precautions

Even though there isn’t much that can go terribly bad with sail boating, you need to be cautious of anything else in the water for an enjoyable RC sailboat adventure.

Besides that, check to verify that your RC sailboat is in perfect working condition. This includes examining all components, ensuring secure connections, and confirming proper functionality.

Make sure that all the openings on your boat are closed up before setting off on the water. If you have an open window at the top, tape it up! Also, make sure any drain plugs are securely pressed into the boat to stop any water from getting in.

Lubricate the bearings, like those at the top of the “gooseneck” and underneath, located at the bottom of the sails.

On large bodies of water, make sure you have certain backup plans in mind, like retrieving your boat if it gets stuck or floats out of range.

Props matter too, you know! When considering performance, you might also want to check out the difference between a 2-blade and a 3-blade prop for RC boats . The type of propeller you choose can influence how efficiently your sailboat glides through the water.

Adjusting the Jib

Make sure to adjust the jib, the smaller sail at the front of your sailboat, to work together with the bigger sail and enhance its performance. It will help you find a balance between stability and fast sailing and help your boat float smoothly through the water.

Basic Maneuvers

Although the movements aren’t as sudden as cars and planes, steering is still paramount to navigating your RC sailboat effectively. Turning the rudder in the water allows you to turn the boat as it cuts through the water. It controls your sailboat’s direction and maintains precision on the water, whether it’s upwind or down.

Learning how to control the rudder skillfully will help you move in any direction, as long as you have the same amount of skill with the sails. Be patient and allow some time to pass when you controlling the boat. The sails will react quickly with any wind but the rudder takes a few seconds to impact the direction of the boat.

Whether you’re adjusting your course or responding to wind shifts. There’s not much advice I can give you other than to practice in calm environments until you feel comfortable with it.

Sailing Upwind

Sailing against the wind requires certain sail adjustments and precise steering. It can be challenging because of the wind resistance, but you can overcome this by using certain maneuvers. To sail upwind, use techniques like tacking.

Tacking and Jibing

Tacking and jibing are fundamental maneuvers for efficiently changing your sailboat’s direction. These skills are essential for navigating complex routes and racing competitively.

Use tacking to move into the wind. Tacking is when you turn the front of the boat towards the wind while slightly steering from left to right through the water. In this way, the wind should hit the sails on one side and then the other as you’re steering into the wind.

Jibing works in the opposite direction of tacking and is a technique for moving very quickly with the wind.

Tacking and jibing will help you to navigate intricate paths, especially when competing in races with demanding courses.

In conclusion

The controls of an RC sailboat transmitter aren’t too complicated. As for the sailing, remember to use the wind and the water in harmony. Keep all the components of the boat in mind when navigating through the water.

Start out slow with smaller sails and work your way up. Practice is key for getting to know the behaviors of your sailboat.

This awesome hobby has something for everyone, whether you like to build your RC from scratch and keep modifying till you've got it to just how you want it, to track racing. You might be out with a boat, or perfecting your skills with a plane. Are you taking some cool pics with your drone? I'm sure my site will help you on your journey.

how to make rc sailboat sails

. In that thread I show several techniques for casting lead bulbs from simple plaster molds to complex CNC aluminum machining.

In this thread I will be doing some similar things, but will not be rehashing some of the intricacies that I have already delved into there, such as the aspects of CAD design and CAM processing. Similarly, I won’t be describing EVERY technique available, just the ones I use for my own projects.

Hopefully, this will make things a bit easier on me as far as documentation so I am hoping to be able to get things done in 6999 steps instead of 7000 this go around!

I also have another build thread going that details the building of the Alioth, a 3d printed IOM. . I will be showing how I make the foils for that boat in this thread.

The plan is that these threads will all start to merge together into a finished project as I progress. The bulb and foils threads showing construction techniques for those parts and the boat thread showing the installation. I am keeping these aspects separated because, as in the casting thread, I work on several casting projects. Likewise, I will be doing more than just the Alioth IOM foils in this build thread.

Just as in the other threads, I am starting out with a blank slate. I am no expert in making these things and in fact have never made an RC boat rudder or keel fin before. I think this is very important to point out because I want YOU to be able to say to yourself, “If this idiot can do it, maybe I can too!”

That being said, I have some past experience that I am bringing to the table. I have a 25 year background as a professional woodworker and bench jeweler. Nearly three decades in computer art and design work. I have a shop filled with WAY more than the average amount of tools. If there is something in my head that I want made, it is generally gonna get done.

One of my key past experiences that will apply in this thread is that I have a history of building with composite construction. I used to be as much into high performance sailplanes as I am currently into sailboats of the same caliber. If you were flying a Taboo GT or XP-5 discus launch glider a decade or so ago, I probably made your fuselage. I was also making DLG carbon tailbooms and made the first fuselages and booms for the Mark Drela XCBD (Cross-country Bubble Dancer). I even built my own CNC 4-axis foam cutter from scratch to make cores for composite sailplane wings and rudders.

So, yes I am new to sailboat foils, but will be bringing a lot to the table. I hope to have some fun and do a lot of learning. I also hope for participation and advice from others that have already been down this road. I cannot stress how important it was in my bulb casting thread to stand on the shoulders of others. I will be doing a lot of the same here. I am not an engineer, I just write the manuals.

Graham Herbert thinks nature may have figured out a good shape for his IOM foils already.
.


So, there are some definite starting points mentioned above. I have found that there are many roads to take and each builder has their own little twist to add. I am not sure there is a perfect solution, but half the fun is in trying to find one anyway.

Someone is screaming at their screen right now. “OMG how can you put forth info on designing a rudder for a boat without doing the dozen calculations required for proper this that and the other effect of blah blah blah., etc.”

Look man, I am not here to present a dissertation. I am here to show you how I built a pretty decent IOM rudder that is probably gonna work out fine. See the previous post for my thoughts how things are going to be OK even if you don’t do the math. This is just a prototype whose sole purpose is to verify that I can make a thing that looks about like an IOM rudder to start with.

Think about this thread as a vocational tech. class mixed with arts and crafts, not a science class. It is the way I know how to work. Yeah, I took Honors Physics in High School, but even in an Honors class somebody had to get the lowest grade in class and barely pass. Not ashamed to say that in 1991 that person was me!

This keel fin is by Gabriel Le Duc. He is doing some nice work in Southern France and I have been following his progress on FB.

Here are experiments from weeks ago showing early 3d print tests leading up to this. Is that a vacuum chuck plate and CNC carved foam cores on the left? Sure is, but that will come later. Right now, we are in printer land!
.
I just want anyone that hasn’t been there before to go check it all out. The doc you want is in “Other” and called Center of Effort Location - fin or rudder. I will also have the PDF for direct download at the bottom of this post.

I won’t re-type the instructions, as they are fairly clear on the process. Here is a detail you should pay attention to. Notice the line chosen as the bottom width of the rudder is not at the bottom of the rudder. The rudder tip has a radius to it and Sailsetc. has picked a location about midway through that curve. If you also notice that if you cut the tip off that line, you could about fit that tip piece in the gap near the leading edge that line.

This eye-balled line is a bit of a guess. Likewise the location of of the rudder stock axis is said to be placed “no less than 3mm ahead of the center of effort point”. OK, but is there not a “no than Xmm ahead” limit. So, I chose a spot that was 4.5mm ahead of the CE because that as also the location of the thickest point of the rudder airfoil to give maximum room for the rudder stock.

When typing up this post I did not want to get complex, but wanted to do more than just throw out the term Center of Effort and devote a post to finding it with no other info at all on why it matters. Luckily, I found some info presented at at a simple level without using any math titled The Physics of Sailing. Take a look here.

Mr. Pierce says that CE and CLR represent the centroid of the average forces that are contributed by the foil. So Sailsetc. has provided a way to find that by estimating the location of the centroid (Center of Effort) of the area of the rudder or fin from a 2D view. I used their instructions to find that location with my CAD software. But I also have the ability to push a button and have the software find that exact centroid point using the 3D shape and did so after doing it “manually” and compared locations.

Well dangit, they aren’t in the same place. Rhino3D says the 3D volume centroid is about 10.9mm behind and 7mm above the Sailsetc. 2D area centroid position. Hmmm.

I proceed to the next step in the instructions which tell you to draw a line from that point to the leading edge and bisect it. I do so and have a minor jaw drop when I see where the midpoint of this line is. If you recall the CE point calculated by the Sailsetc. 2D method places the rudder axis “no less than 3mm” forward from the CE. My computer has taken the complete 3D data of the rudder and found that axis line at this EXACT 3mm offset location.

It is kinda cool that you can bypass some advanced math by essentially just saying “move this point ahead about 3mm in the 2D view to make up for the contributions of the 3D volume and you will probably be alright”.

Finally, a picture! Here is a mold half, fresh off the printer.
.


This looks like an unfinished sanding job, but this is the point you can stop at.
.
You can also order from Smooth-on, which is where the Amazon stuff ships from anyway, so check to see if you can save buying direct.

Make sure your molds are free of any dust, grit, and crud. I mixed up a 15cc batch of epoxy for each mold and did them one at a time so I could keep the epoxy flowing and runny. I only coated the tops of the molds. No reason to do the sides and back.

I used a 1/2” shop brush to apply it all over the top. It helps to focus on getting it a bit “rubbed in” to the plastic. The epoxy may try to pull away from the plastic in a few spots, but working it in just a bit will get it to behave. Make sure there are no puddles, thin spots, or brush hairs (or your hairs) on the surface. Then take several passes down the long axis with your brush, smoothing and evening the coat out while working in full length strokes from tip to the open end of the mold so that excess epoxy is removed as I go.

What works nicely at this point is to apply some gentle hot air while holding the mold vertically. This will help surface air bubbles to expand, pop, and self level. It will decrease the viscosity and helps excess epoxy slide down and off the mold. It can also help you smooth out runs and sagging.

I have a small heat gun that works great for stuff like this and is fantastic for heat shrink as well. I use it for all kinds of stuff.

CAUTION: Do not overdo the heating. You can burn the epoxy or soften the mold. You can cause curing to begin immediately. You can cause tiny bubbles become huge, hardened lumps. What you can get away with will depend on your heat source. Test out your technique on a sample print before you coat the molds. I have quickly flashed a propane torch over epoxy for a second or two just to pop bubbles. I have also spent a minute of time working on flattening a run with a low temp heat/air source. Experiment until you have some experience.

Now stand your mold vertically and leaned back a bit so no epoxy accumulates at the open base. It is fine for it to run off the end and drip freely. You can pop the runs off the mold base with a chisel later.

Don’t be too disturbed with how it looks. My pictures below will show you several mistakes, such as a trapped hair in the black mold. Also, hardened bubbles because it was hot as Hades in my shop that day and the epoxy was bit too stiff by the time I remembered I needed the hot air gun. I even had epoxy build up the open end because I forgot to tip the molds back once I had my area cleaned up for the day. The first coat of this stuff almost always looks like poo, even on my best days. It will come out fine in the end.

Looks ugly? Yep. No worries. It will get taken care of.


First coat is on. Not pretty, but it is even.
.


This is the black mold from the previous post after being having the first coat sanded, but before the 2nd epoxy coat. I told you it was going to come together! Don’t sweat those scratches. Coat #2 will manage them.

How to make a rc sailboat

Make a rc sailboat.

After two weeks at the Wooden Boat school I had finished the ruff-in of the hull, mast, electronics and sub deck ready to start the final assembly.

Here you see the 1/16 inch plywood sub-deck has been removed. I have added ribs to help support the shape of the sides.

Here you see, that all the ribs are in place, I have added epoxy to unify and strengthen the hull.

Fair the hull but don't spend a lot of time on it right now.

Establish the center lines this is when I shape the keel and ballast.

Take pictures and use the black & white mode to help see any fluctuations in the keel.

Try different exposures

A PVC pipe building support makes a big difference for accurate work. It's important to have complete & easy access to the hull at this point.

I use epoxy to seal the underside of the deck, two coats, while it's tacky I apply thickened epoxy to the deck beams and sheer.

Lay the decking from the outside toward the king plank.

To get a deck to look right do not only look at where the points meet but also the trailing edge of the plank. You may need to trim each side of a deck plank to keep both sides of the deck even.

Don't rush!

The design of the deck is completely up to you;-)

You may like contrasting wood or a reproduction look like this?

I put the epoxy finish on before the hatch combing. I think it makes it easer to get a smooth finish.

Needs buffing to improve the look and feel.

RC Sailboat Controls – Radio Layout, Radio Setup

RC Sailboat Controls are rather different then your typical Radio Control.

We will first look at what channels on the radio control transmitter, control which part of the RC Sailboat and then we will look at the specific setup concerning the radio gear on an RC Sailboat.

Transmitter Channels and Controls – RC Sailboat Controls

The most common type of transmitter for RC Sailboats are the stick type transmitters . The stick type transmitter allows the ease of use over the sail control. On a stick type transmitter referring to the image below, the left

RC Sailboat Controls - Radio Control Channels

RC Sailboat Controls

side channel, typically throttle on an airplane controls the Sails. Moving the left side stick up or down would draw the sail in or let the sail out. Motion on the stick is vertically.

The stick on the right hand side controls the rudder on the RC Sailboat. The rudder channel operates as like any other rudder channel. Motion on the stick is horizontally.

These two channels are the required minimum for RC Sailboat Controls. You can see all the extra switches and controls on the radio to the right. These may be used for controlling those fancy features on your RC Sailboat. In some cases these extra features include alternate lighting, winches, or anything else to make the sailboat appear and operate more scale like.

Radio System Controls – RC Sailboat Controls

RC Radio Receiver

RC Radio Receiver

Now that we have talked about the transmitter we will look at the rest of the components that are required in order to run an RC Sailboat. The component that is responsible for talking to the transmitter is the receiver. The receiver is what talks to the transmitter and then converts the radio signal to an electrical signal that can be used to control the rudder and sails of a sailboat. The reciver can be purchased with the transmitter if you choose to take that route. Purchasing a transmitter/receiver combination is more common when building your own boats.

Receiver Battery – RC Sailboat Controls

To power the radio equipment a standard receiver battery is required. This is a battery that operates on 4.8-6.0v. Although a 4 cell disposable AA case can be used, it is highly recommended for an RC sailboat to use a rechargeable battery . The main reason is to ensure the battery pack can supply a sufficient amount of current to the servos. For larger RC sailboats a rechargeable battery is a requirement. The average user would use a 4.8-6.0v NiMh pack however LiFE, Li-ion, LiPo packs are available but be certain to include a Voltage Regulator in your system to limit the voltage.

 Sail Servo – RC Sailboat Controls

The most important servo for an RC Sailboat is of course the Sail Servo. The sail servo comes in two different styles that are most common. Each style has its own specific set of advantages and disadvantages. The first  style of sail servo that we will talk about is the sail winch servo.

The sail winch servo as pictured on the right hand side uses a drum like wheel to house the sail line. When the drum rotates the line is either let out or brought in. The Sail winch servo typically allows for 3 rotations of the drum with

Sail Servo Winch -  Sail Servo - RC Sailboat Controls

Sail Servo Winch –  Sail Servo – RC Sailboat Controls

torque specs around the 150 oz-in / 11 kg-cm. The biggest difference is that these torque specs are at a relatively short distance from the center point of the drum. This small distance increases the amount of torque relative to the next sail servo type that we will be looking at.

Sail Winch Servo Advantages:

  • Amount of force generated to pull in the sails
  • Amount of  total line length (travel) that can be brought in – approximately 3 revolutions of the drum
  • Relatively Small Space Requirement, even with larger servo sizes

Sail Winch Servo Disadvantages:

  • Slow Reaction time relative to transmitter input as winch must rotate up to 3 times

Sail Arm Servo - RC Sailboat Controls

Sail Arm Servo – RC Sailboat Controls

The other Sail Servo style is the arm type . The arm type sail servo uses quite a long arm in order to get an acceptable amount of line draw. As you may expect this operates nearly the same as a standard servo where the only difference is the servo arm itself. For a typical one meter Sailboat, you would require a servo of this style that has at least 150 oz-in / 11 kg-cm of torque as a minimum. This style servo requires more torque then a winch servo as the amount of force produced at the end of the arm is reduces due to the length of the arm.

Sail Arm Servo Advantages:

  • Very quick response time vs the Sail winch Servo
  • More servo options as any standard servo can be used with a long sail arm. Options for very high torque servos are available
  • Line has less chance of getting tangles or wrapped upon itself as compared to the winch style servo

Sail Arm Servo Disadvantages:

  • Require a lot of space due to the radius of the outer point of the sail servo arm
  • Lower amount of Line Draw force due to length of Arm requiring higher torque at the servo for equal performance that of a winch style servo
  • Generally has a smaller total line length(travel) that can be brought in resulting in lower amount of sail movement (travel)

Steering Servo – RC Sailboat Controls

This is really where you’ll be able to find a boat that perfectly fits your needs, whether you're looking for anti-capsize functionality or the ability to go into saltwater. </p><h3 class="body-h3">How We Selected</h3><p>To create our list, we looked at each model's speed, safety, and durability, as well as other special features, to ensure these boats will leave buyers satisfied. On top of that, we have made sure that each of the boats we selected an average customer rating of 4 out of 5 stars or higher, ensuring you’re getting a quality product no matter which model you select. We’ve picked options for every type of RC boat customer, whether you're a casual hobbyist, buying a first boat for your kids, or are a full-on RC enthusiast.</p><p><strong><em>For more top-rated toys that will make you feel like a kid again, check out our picks for the best <a href="https://www.popularmechanics.com/technology/g37950230/best-remote-control-cars/">remote control cars</a> and the best <a href="https://www.popularmechanics.com/cars/g38281423/best-remote-control-trucks/">remote control trucks</a>. </em></strong></p>

If you’ve ever seen a remote-control boat skate across the water—or controlled one yourself—you know it’s a good time. These toys can accelerate up to 50 miles per hour, tearing up the waters in your favorite lakes, pools , rivers, and, if you like risk, seas.

RC boats come in lots of shapes, sizes, and styles, but the best models can shred water from afar without becoming sinking ships. We’ve rounded up the best remote-control boats for beach visits, lakefront races, poolside entertainment, and some advice on picking the best RC boat for you.

Stay in play and check out our picks for the best magnetic toys , remote-control trucks , and remote-control planes .

The Best RC Boats

  • Best Overall: ALPHAREV RC Boat with Case R308
  • Best for Beginners: DEERC RC Boat with LED Light
  • Most Well-Rounded: Altair Aerial AA102 RC Boat
  • Best Value: Force1 Velocity H102
  • Best Sailboat: PLAYSTEAM Voyager 400 RC Sailboat

What to Consider

While you can likely get away with using a larger RC boat on a pond or lake, you may want to stick to a smaller model if you’ll be floating yours in a backyard swimming pool or need to pack something tiny. RC boats can be up to two feet long, so make sure to consider the journey to the water, too, especially if the boat you’re eyeing doesn’t come with a carrying case.

Weight and Speed

The RC boat’s weight helps determine how fast it can move. Heavier boats are better equipped to move at high speeds without capsizing, whereas lighter boats can be speedy using less power, a.k.a., slower acceleration. Think of it like torque on a car (or a full-sized boat, for that matter)—the more power the boat gets from the battery, electric, or gas motor, the faster it can accelerate.

Speed is also dependent on the type of hull—some boats are shaped for optimal turning and curves, while others are built for picking up speed while driving in a straight line.

The priciest models can reach speeds of up to 50 miles per hour. We mostly recommend recreational, battery-powered RC boats that reach speeds up to 30 miles per hour, since the more powerful, expensive models are meant for hardcore hobbyists and professional racers.

Capsize Recovery

Many RC boats have anti-capsize, or capsize recovery, functionality to prevent them from flipping over (and staying overturned). Flipping an RC boat is extremely easy, especially if you lack experience, and can lead to a sinking ship. If you’re new to RC boating, consider grabbing one with capsize recovery, making your boat rebalance and flip back over if it tips.

How We Selected

5) Voyager 400 RC Sailboat

If sailing is your preference, the Voyager 400 is the way to go. Rather than rely on an electric motor to push it forward, the Voyager 400 can sail in any body of water via wind power. Its remote controls the rudder and the propulsion, and just in case wind isn’t in the forecast, it comes with a detachable motor to help propel it.

Customers say it’s easy to use, and everything is sealed to keep interior components dry when it tips over. Its rechargeable remote battery can work for up to one hour, which puts most RC speedboats to shame. A drawback, however, is that if it gets stuck at sea without the motor attached, you’ll have to wait for it to wash ashore.

<p><strong>$41.69</strong></p><p><a href="https://www.amazon.com/dp/B07ZFPJPL3?tag=syndication-20&ascsubtag=%5Bartid%7C10060.g.40717811%5Bsrc%7Cmsn-us">Shop Now</a></p><p><strong>Key Specs </strong></p><ul><li><strong>Dimensions:</strong> 13.5 x 3.5 x 3.5 inches</li><li><strong>Weight:</strong> 11.4 ounces</li><li><strong>Speed:</strong> 15 mph</li><li><strong>Special Features:</strong> Capsize recovery</li></ul><p>Cheerwing RC boats are awesome if you're looking for an affordable toy that still reaches high speeds. This boat can hit up to 15 mph and has some great features, including capsize recovery and automatic yaw correction. It also signals you when the battery is low or when it starts to lose signal, which will give users peace of mind knowing the battery won't die unexpectedly in the middle of an adventure. </p><p>Whether you're looking for a cheaper boat to add to an existing RC boat arsenal or are a beginner and don't want to spend too much on your first boat, this is a great choice at a wallet-friendly price point. </p>

6) RC Racing Boat

Cheerwing RC boats are fantastic if you’re looking for an affordable toy to race with your friends. This boat can hit up to 15 miles per hour and has some great features, including capsize recovery and automatic yaw correction, which rebalances your boat. It also signals when the battery is low or starts to lose signal, giving you peace of mind.

If you want to try RC boating without spending much, this is a solid buy. Its biggest downside is in its battery life—just six to eight minutes per charge—and it doesn’t come with the option to buy a second battery, so it requires frequent recharging.

<p><strong>$259.99</strong></p><p><a href="https://www.amazon.com/dp/B09JWJGR6T?tag=syndication-20&ascsubtag=%5Bartid%7C10060.g.40717811%5Bsrc%7Cmsn-us">Shop Now</a></p><p><strong>Key Specs </strong></p><ul><li><strong>Dimensions:</strong> 27.56 x 7.48 x 5.31 inches</li><li><strong>Weight:</strong> 4.44 pounds</li><li><strong>Speed:</strong> 40 mph</li><li><strong>Special Features:</strong> High waterproof design</li></ul><p>If you have a need for speed and don’t mind investing a little more money into your hobby, this boat is awesome. It is by far the fastest model on this list, reaching 40 mph—twice the speed of our next-fastest option. </p><p>With such high speeds, the design of this boat has many features to protect it such as a high waterproof design and a unibody hull to prevent any cracks and damage. If you’re looking to blow your friends out of the water, this is the boat for you!</p>

7) Brushless RC Boat

If you need speed and don’t mind investing more money into your hobby, this boat is fantastic. The fastest model on this list, this boat has a top speed of 40 miles per hour, a range of up to 656 feet, and a water-cooled system that prevents the motor from overheating.

It also has safety features to prevent damage from the high speeds, like waterproofing and a one-piece hull to prevent cracks.

The biggest flaw is its lack of capsize recovery, and several users say their boats flipped in action, causing them to swim out to retrieve their toys. It also only comes with one battery.

Event Recap: US Open Sailing Series – 2024 Long Beach Olympic Classes Regatta   

  The 2024 US Open Sailing Series for the Long Beach Olympic Classes Regatta at Los Alamitos Bay Yacht Club in Long Beach, California, delivered an exhilarating week of competitive racing, featuring a diverse fleet of sailors across multiple classes. This event, an integral part of the sailing calendar, showcased both seasoned competitors and promising young talents.  

The event brought in a combination of Olympic, Invitational, and Youth World Classes for competitive racing in Southern California waters.  

The Long Beach venue, renowned for its challenging conditions and scenic backdrop, provided the perfect setting for this prestigious regatta. As the sailing community looks ahead, it’s worth noting that Long Beach will serve as the sailing venue for the 2028 Summer Olympics, promising more thrilling races and showcasing the world’s best sailors.  

“Extremely competitive classes showed up to race in stellar Long Beach conditions providing 12-17 knots on Friday and Saturday and 8-10 knots on Sunday,” shared Regatta Co-Chair and Long Beach Yacht Club Vice Commodore, Lisa Meier. “Coaches and competitors were at the highest levels. One just had to look at the ILCA 6 course to world class competition to see Charlotte Rose/USA, Lillian Meyers/USA, and Wiktoria Golebiowska/Poland battling it out in world class conditions!  All classes provided stiff competition with lead changes throughout the regatta.”  

Class winners:    

  • 29er: Kevin Cason + Holland Vierling, San Diego Yacht Club  
  • 470: Kyra Phelan + Sawyer Bastian, St. Francis Yacht Club  
  • Finn: Rob Coutts, Mission Bay Yacht Club   
  • Formula Kite: Adam Keaton, Fastmetrics   
  • ILCA 4: Nate Colbert, Mission Bay Yacht Club  
  • ILCA 6: Wiktoria Golebiowska, Poland*  
  • ILCA 7: Hamilton Barclay, Barclay Sailing   

*Denotes international competitor  

Five of the seven class winners hail from California, representing the West Coast at the event.  

“The Long Beach Olympic Classes Regatta is designed to run during the Olympic window,” noted Mike Van Dyke, Chair of US Sailing Board of Directors and Staff Commodore of both Long Beach Yacht Club and Los Alamitos Bay Yacht Club. “It’s a preview of the day of how the sailing will look for LA28. Next year, we expand the number of classes as we welcome back the 49er, FX, Nacra 17, and iQFOiL. The Format expands to 9 days with each class racing 4 days. We’re partners with the City of Long Beach, welcoming and hosting visiting athletes as they move from Paris to Long Beach.”  

The 2024 US Open Sailing Series not only highlighted the current elite sailors but also served as a critical platform for emerging talents to make their mark. The event reaffirmed the vibrant and competitive spirit of sailing, setting a high bar for future regattas.
