X-402 is a 39 ′ 7 ″ / 12.1 m monohull sailboat designed by Niels Jeppesen and built by X-Yachts between 1984 and 1990.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Based on the X 1 TON. (1986 Int. One Ton Cup winner). Available with masthead or fractional rig.

We had a weekend in Athens and limited prior sailing boat experience; wanted to relax, experience a more localized tour, do a bit of snorkeling etc and found Tolis' listing. Visited Aegina island's many different spots including the Afair temple, Moni, Perdika and various areas to snorkel. Breakfast and lunch on board was excellently prepared by Brenda - we enjoyed thoroughly. Dinner was at a local Greek restaurant on Perdika which was also very good. The boat itself was lived-in with tweaks here and there that made it feel much more personalized than other stock boats. It was spacious for our party and well maintained. Through the weekend we got to learn (and help out) a little bit more about the art & science of sailing from both Tolis and Brenda which was both insightful and interesting. It was a great experience and checked all the boxes we had in mind.

Russia’s improved Kilo-class submarine entering Black Sea

In the midst of ukraine-russia tensions, russia's improved kilo-class (project 636.3) submarine "rostov-na-donu (b-237)" entered the dardanelles on february 12 en route to the black sea. the submarine belongs to the black sea fleet's 4th independent submarine brigade..

Tayfun Ozberk 12 Feb 2022

Rostov-na-Donu will transit Bosphorus tomorrow morning and enter the Black Sea. Following the deployment of Rostov-na-Donu , the Russian Black Sea Fleet will have four improved Kilo-class submarines equipped with Kalibr land-attack missiles in the Black Sea. According to the OSINT reports , the Black Sea Fleet’s other two Project 636.3 submarines (B-262 Stary Oskol , B-265 Krasnodar ) are currently in Russia’s Tartous Naval Base in Syria.

Russia has been reinforcing its Black Sea Fleet since last week. As Naval News reported on February 08, the first part of a Russian Navy amphibious landing ship force consists of three Ropucha-class amphibious assault ships ( Minsk (127), Korolev (130) , and Kaliningrad (102)), which can carry troops, tanks, and supplies, has entered the Black Sea. On February 08 , three additional amphibious vessels (Project 775 (Ropucha-class)  Georgy Pobedonosets  (016),  Olenegorsky Gornyak  (012), and Project 11711 (Ivan Gren-class)  Pyotr Morgunov  (017)) of the Russian Navy transited the Bosporus tonight to enter the Black Sea.

In addition to the current tensions in the region, Russia issued NOTAMs in the Black Sea on February 9, effectively blocking the entrance to the Sea of Azov as well as the ports of Mariupol and Berdyansk. The NOTAMs were released in preparation for the Black Sea Fleet’s live missile and gun firing exercises, which will take place from February 13 to February 19, 2022.

The naval capabilities of both countries and the Russian Black Sea Fleet’s possible course of action are given in our January analysis .

About Improved Kilo-class submarines:

Improved Kilo-class submarines are referred to as the third generation of large diesel-electric submarines, which were built at the JSC Admiralty Shipyards for the Russian Navy’s main fleets. Originally, these submarines are called Project 636.3, in Western countries, they are defined as Improved Kilo-class, which are the upgraded version of  Project 877 (Kilo-class) subs.

The improved Kilo-class submarines are designed to conduct anti-shipping and anti-submarine missions in shallow waters and feature stealth technology with extended combat range to strike land, surface, and underwater targets.

According to Russia, the Project 636.3 submarines are among the world’s quietest submarines. It is 74 meters long, has a displacement of over 3,900 tonnes, and has an operational depth of 240 meters. It can operate at a maximum depth of 300 meters and has a range of 7,500 nautical miles.

The submarines have a cruising speed of 20 knots, a range of 400 nautical miles using electronic propulsion, can patrol for 45 days, and can accommodate a crew of 52. They are equipped with 6×533 mm torpedo tubes with 18 torpedoes and eight Strela-3/Igla-1 surface-to-air missiles. Alternatively, the torpedo tubes can deploy 24 mines.

These submarines are powered with two 4DL-42M diesel generators, 1500 kW each (1000 kW each for the first 2 diesel generators). Different from Project 877 submarines which have a 6 bladed propeller, Improved Kilo-class subs are fitted with a 7 bladed propeller.

The MGK-400EM digital sonar is installed on Type 636.3. The sonar suit, according to Robosonexport, detects submarine and surface ship targets in sonar listening mode, echo-ranging in a 30° sector of the target relative bearing, telephone and telegraph communication in both long and short-range modes, detection of underwater sound signals, and signal-bearing determination.

Ukraine trolls Russia for losing an attack submarine to a country that hardly has a navy

• A new video from Ukraine's defense ministry pokes fun at Russia for losing the Rostov-on-Don submarine.
• The video trolls Russia for losing a submarine "in a land war" to a country "without many warships."
• The Rostov-on-Don was likely damaged beyond repair in an attack on Sevastopol last week. 

Ukraine is taking a victory lap after a devastating attack on a key Black Sea port last week, trolling Russia's apparent loss of an attack submarine in a new video. 

The video, posted on X, formerly known as Twitter, by the Ministry of Defense of Ukraine, pokes fun at Russia for having "lost a submarine in a land war." 

Related stories

"Wanna know why Ukraine will win the war?" the video reads. "Well, among other things... we're a country without many warships, and we just destroyed a Russian submarine." Ukraine's navy is limited in capability, and its flagship was actually scuttled shortly after the invasion to keep it from falling into the hands of the Russians.

—Defense of Ukraine (@DefenceU) September 20, 2023

Indeed, photos that surfaced online in the days after Ukraine's strike on Sevastopol appeared to show the Kilo-class submarine Rostov-on-Don wrecked , with severe and widespread damage to its exterior and possibly interior. An expert told Insider the pictures of the damage, particularly to the pressure hull, suggested the attack left the vessel beyond repair. A potential loss of critical repair facilities only further supported the assessment.

According to Oryx , which keeps a tally of Russian ships taken out by Ukraine, the Rostov is the first recorded submarine loss for Moscow in the war. And, according to warfare expert Franz-Stefan Gady, it's the first combat loss of a Russian submarine since 1945.

—Oryx (@oryxspioenkop) September 18, 2023

The Rostov-on-Don was one of the Black Sea Fleet's four improved Kilo-class submarines capable of carrying cruise missiles. They are formidable assets that have been responsible for striking Ukrainian targets and defending Russia's naval interests in the area.

It was wrecked in a pre-dawn attack on the Sevastopol shipyard by Ukraine last Wednesday, which included the use of cruise missiles — possibly Western-made Storm Shadow/SCALP-EG long-range cruise missiles — and drones.

Russia's Ministry of Defense said it destroyed the drones and shot down seven missiles, claims that are unverified, but a number of weapons made it through, causing extensive damage to the facility, the Rostov, and the landing ship Minsk, which Britain's defense ministry, citing open-source evidence, suggested had "almost certainly been functionally destroyed." 

The hit on the Rostov is the latest in a string of high-profile attacks by Ukraine against Russian forces in occupied Crimea.

In August, Ukrainian officials said they'd modified a Neptune anti-ship missile, the weapon that killed the Russian Black Sea Fleet flagship cruiser Moskva last year, to strike and destroy an S-400 Triumf near Olekivka on the western side of the peninsula. Another S-400 — a prized mobile, surface-to-air system that's capable of shooting down cruise and ballistic missiles, as well as aircraft and drones, at high altitudes and long ranges — was apparently taken out earlier this month in Yevpatoriya, another western city in Crimea. 

Unmanned surface vehicle attacks on warships and a key bridge in recent months have made the Black Sea a nightmare for Russian naval forces to navigate and defend. An expert previously told Insider these relatively cheap exploding drone boats — remote-controlled sleek, black watercraft around the size of a life boat — give Ukraine an asymmetric edge , causing massive damage to targets like the the Ropucha-class landing ship Olenegorsky Gornyak. 

Ukraine's attacks, including a surprise amphibious raid in late August, on Crimea are both strategic and symbolic , as Kyiv hopes to ultimately make the peninsula "untenable" for Moscow's forces , a former US Army general previously told Insider, and sets up the contested peninsula as the most important area to reclaim in the larger war. 

Watch: What's next for the war in Ukraine?
