planing hull boat
Boats with planing hulls can skim along at high speed, riding almost on top of the water rather than pushing it aside. flat-bottomed and vee-bottomed hull shapes act as planing hulls. most small power-driven vessels, including personal watercraft (pwc) , and some small sailboats have planing hulls, allowing them to travel more rapidly across. Planing hulls are more efficient at higher speeds, although they still require more energy to achieve these speeds. an effective planing hull must be as light as possible with flat surfaces that are consistent with good sea keeping. sail boats that plane must also sail efficiently in displacement mode in light winds..

planing hull boat But on a planing hull, the center of effort shifts further aft as the hull rises out of the water. this forces the designer to balance most of the boat weight near the transom. at extreme speeds, the effect becomes so excessive that the engineer completely redesigns the hull shape to compensate.. I find the whole hull speed and speed/length thing unsatisfactory when talking about boats capable of planing. it may be useful in some circumstances but often does more harm than good. to look at a specific example of how the above reasoning was applied, we will turn to a boat of my own design which is the featured boat of this website and.
