A 100,000 lb displacement boat will require less than 50 hp to cruise. you should be able to get 10hp in the water from every gallon of gasoline , perhaps 16hp from every gallon of diesel. operating efficiency is harder from the diesel as they don't handle light loads very efficiently , gas is easier to set up.. Boats with displacement hulls are limited to slower speeds. a round-bottomed hull shape acts as a displacement hull. most large cruisers and most sailboats have displacement hulls, allowing them to travel more smoothly through the water..
