  1. Catamaran Hull Speed Calculator For Beginners (Table and Free

    This is the formula for Maximum Hull Speed on a displacement boat: Max hull speed= √((Length on Water Line x g) /(2 x pi)) x 3600/1852. Now we need to add the increased efficiency (loss of drag) of a semi-displacement hull, usually, this is somewhere between a 10-30% increase. Semi Displacement hull speed = Maximum hull speed * 1.3.

  2. Power Catamarans: A Complete Guide

    However, the power catamaran is a relatively modern innovation that marries the traditional twin-hull design with powerful engines, offering a unique blend of speed, stability, and space.

    This usually means anyone at the front or sides of the boat takes most of the jostling,"Myers says. "The catamaran-style hull delivers ride comfort, smoothness, load distribution, and stability."That stability draws anglers to powercats of typically 20 to 40 feet; and cruisers to sailing cats 40 to 60 feet and beyond. — Rich Armstrong.

  7. Cruising Catamaran Speed! With Examples and Explanation

    When the load is higher, power catamarans speed drops to 15-20 knots. ... There are several features of a cruising catamaran that impact its speed. These include: The type of hull. The less the hull is submerged into the water, the faster the catamaran will go. When they are submerged, hulls create drag which slows the velocity of the boat.

  8. High Performance Speed Boats: The Ultimate Go-Fast Guide

    Offshore V-Bottom Monohull Speed Boats. The offshore monohull V-bottom is still the quintessential high-performance powerboat. The boat's length dictates the waves you can take on safely and comfortably. Typically, high-performance V-bottom measures from 25 feet and up to over 50 feet.

  9. Catamaran Hull Design

    If you have fine hulls you can use a lower Cp. Most monohulls have a Cp of 0.55- 0.57. And that is about right for displacement speeds. However the key to Catamaran design is you need a higher Cp if you want to sail fast. So a multihull should be at least 0.61 and a heavy displacement multihull a bit higher still.

  10. Power Catamarans: A Comprehensive Guide

    This Florida builder is one of the few in today's marketplace that builds a wide range of both monohull and power catamaran boats.

  15. Sail And Power Catamarans: Developing A 'Catitude'

    A bridle should be preset with a line from each hull (under the trampoline) and hook or shackle in the middle. Once the anchor and chain is down, attach the bridle to the chain (usually done near the windlass) and set the hook putting the pressure on the bridle. Once set, let out enough chain to create a catenary.

    87689 posts · Joined 1999. #1 · Dec 28, 2007. The hull speed formula for displacement monohulls is 1.34 x the square root of the waterline length. When planing, a monohull will exceed it's hull speed. Obviously this formula doesn't apply to catamarans. Even when not planing, they will travel much faster than what the hull speed formula predicts.

    This "displacement speed" indication is perhaps a better metric and allows calculation of the standard "hull speed" calculation of 1.34 x sqrt(LWL), with a "displacement speed" changing the multiplier from 1.34x to 1x or 1.1x (so a 49′ boat would average 7-7.7kn, a 64′ boat would average 8-8.8kn).
