Full Displacement Hull Boat Plans






Displacement or semi-displacement or planing hull boat plans & full size frame patterns. this is the smallest of our coastworker range that extends from just 25 ft to 58 ft - an ideal first boatbuilding project... 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.. Full displacement designs are known to move through the water, rather than on top of it, and are considered very seaworthy. their deep and wide hull shape allows for large fuel and water tankage, large storage volume, and typically have large engine rooms in the center of the boat, as well as comfortable living areas..

This is a displacement hull and will never plane. maximum hp is 25, but that will be a bit too much for this moderate size boat. better propulsion options are 4 stroke outboards in the 8-15 hp range, especially those engines that have high reduction ratio gearboxes and slower turning propellers..

With a displacement hull, there is no significant advantage in using an engine that will drive the vessel faster than nominal hull speed at 70 or 80 percent of rated rpm. boats with a lower d/l ratio can be equipped with a smaller, lighter, more economical engine..
