Planing boat theory. first, a disclaimer. for other than purely displacement or semi-displacement boats, hull speed is only of marginal interest. there are many established boat design parameters such as prismatic coefficient, displacement/length ratio, power/weight ratio, center of gravity (in all coordinates), center of floatation as. Key concepts of boat hull design include: the supporting force of the water or "buoyancy" must be greater than the weight of the boat. the thrust from the propulsion system has to overcome the.

A.c. magnum series these hulls have a high lift design enabling the hull to achieve high speed on low nitro fuel or stock engines. this hull design will never hook or tighten up in the corners and has no tendencies of chine walk.. The hull for is a cathedral hull (see previous article of leisure boating). for most planing hulls the chine should be immersed below the waterline from midships (more or less the mid section of the boat) towards aft at a depth roughly 1.5% to 4% of. The design assumed local hull pressure loads of 3g vertical acceleration -- considered fairly high but plausible in open water at speed. bulkhead and stringer locations were arranged accordingly to optimize useable engine room and living quarters without compromising the vessel's structural integrity..
