What Is a Semi Displacement Boat?

A semi displacement boat is built with a boat hull design that features a hull form that is able to generate lift at cruising speed while displacing water at low speeds. These boats are a combination of planing hull shapes, that allow lift of the hull when needed to cruise at speed, while in the displacement mode, they get better fuel mileage and can travel for a long distance since the hull is cruising more efficiently than a full displacement hull.

What Are the Advantages of a Semi Displacement Hull Boat?
