A california hull is a hull shape that combines the elements of the flat hull and a round hull. (largely attributed to tim nemier of ocean kayak fame.) this combination provides performance in tracking, speed (rounded center keel line), greater stability (flat hull) and performance in surfing waves (hydroplaning).. Robert livingston's free kayak design software is suitable for designing strip built small craft hulls. easy to use, prints out bulkhead patterns. connects to free kayak performance prediction software.. Design symmetry, weight positioning, hull materials, water entry line and other more specific features (like sponsons or keel lines) are some of the other factors that manufacturers take into consideration when designing a kayak..
We design hull shapes for the ideal combination of tracking, efficiency, agility and seaworthiness based on the kayaks intended use. many hulls are fairly complex and have different shapes blended together.. The design of a vessel in orca3d begins with the hull model. hull design is a unique combination of artistic expression and engineering analysis, combining to form a creative process to meet the aesthetic and performance requirements of the vessel.. The cad boat design software we are going to discuss here is ideal for the hobbyist. there are two reasons for this. first, it’s free, and second, it provides you with a sufficient number of useful design data items to actually start building a boat hull..
