However, hull design isn’t just about speed and interior volume. there’s also stability and tenderness, which is a boat’s tendency to rock. the boats described above have planing hulls, which means they have hard chines. this creates port and starboard flats that create lift and help plane the boat and keep it on an even keel.. When deep v hulls were introduced they were touted as the last word in planing hull design. these hulls do perform well at high speeds in rough water which is one reason that they are so successful as racing powerboats. deep v planing hulls, depending on the particular design, can be driven at speeds in excess of 50 knots, however most are.

planing boat hull design While i generally ignore the concept of “hull speed” as being irrelevant to planing boat design, it is still a fact that all boats do start out from rest as displacement craft before accelerating to their operating speed and hull speed may be important in getting onto plane in the first place.. 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 maximum chine beam..
