29 Ιουν 2010 · There are two major dimensions of a boat hull: The length of the hull L H and length of waterline L WL . The following consist of arbitrary values to illustrate a calculated example. L H = 12.20 L WL = 12.00
Rating formula. As an open class rather than a one-design, all boat designs must meet the following formula. [3] (all measurements in mm) L = the "corrected" length of the hull (see rule D.6.3) d = the midship girth difference (see rule D.6.4) F = the average freeboard height (see rule D.6.5)
Hull Speed: The maximum speed of a displacement hull (referring to a hull that travels through the water rather than on top of it, e.g. planing). HS = 1.34 x √LWL (in feet)
Use 6.0 to 6.5 as a target for LDR in a glass-sandwich built cruising catamaran. To adjust LDR and fully loaded displacement mLDC, change the length/beam ratio of hull, LBR. We can now estimate our empty boat displacement (kg): mLCC := 0.7 ⋅ mLDC. mLCC = 4995.
3 Οκτ 2024 · The Boat Speed Calculator, powered by Crouch's formula, is a tool designed for enthusiasts and professionals in marine design and navigation. It assesses the potential top speed of boats of various types by considering their power, displacement, and a unique factor known as the Crouch constant.
Hulls of Formula 2 are the same as for Formula 1 boats and they reach minimum length of 4.8 meters and minimum weight of 550 kg (including the pilot). Due to their specially designed tunnel hulls, Formula 2 boats are able to turn almost instantaneously incurring more G forces than any other racing machine on the planet.
How to use the Catamaran Hulls Speed Table. Choose your length on waterline in the left-most column, either in feet or meter. Continue reading to your right and stop either at “Displacement hulls speed” or continue to “10,20, or 30%”, depending on your estimated hull efficiency.
