The downeast hull, even in nasty chop and heavy swell conditions, can cruise comfortable all day long at 12 to 20 knots. today’s true downeast hulls use horsepower to get them up beyond displacement speeds, and yet these boats are still true to the central issue of providing predictable stability.. Purchase plywood motor boat plans for the harbor master displacement 19. we have created wooden motor boat plans for the next evolution of classic dorys! harbor master displacement 19 - study plans it uses a true displacement hull that is suited for lower speed and has low power requirements.. Some hull designers are loath to accept the limitations inherent in these two hull types and so attempt to combine the best features of the planing hull and the displacement hull by creating a design that can exceed theoretical hull speed yet provide the kind of stable, soft ride in waves that a displacement hull is famous for..

Generally less fuel than a "planing" type hull of similar size and displacement. low resistance as long as they are not loaded so that the stern is deeply submerged. the lobster boats have very little deadrise at the transom and moderate deadrise amidships so tend to low resistance unless heavily loaded. very little if any "hump" when accelerating.. The plans give details for the hull to be built in strip cedar with a round bilge hull and a plywood hull which is multi-chined. in both cases construction is rugged and very strong for work use. the hull has a u bottomed shape giving an easy riding displacement hull that can be fitted out in a number of different ways...
