A motor driven hydroplaning boat has a hull of symmetrical generally smooth surfaced configuration which converges towards an apex at a bow thereof and widens amidships to form a pair of laterally and downwardly extending wings. A forward bottom portion of the hull, from the bow to beneath the wings, forms a generally smooth surfaced concave downward tunnel. The wings smoothly narrow aft of amidships and become generally horizontal from amidships aft. A top of the hull is of a generally smooth minimal air resistance shape. A fore foil structure is mounted to extend downwardly from the fore tunnel. An aft foil structure is mounted to extend downwardly from an aft bottom portion of the hull. The overall boat has low air resistance yet overall high stability and can be turned relatively sharply.

A motor driven hydroplaning boat, comprising: a hull of symmetrical generally smooth surfaced configuration converging towards an apex at a bow thereof and widening amidships to form a pair of laterally and downwardly extending wings, a forward bottom portion of the hull from the bow to beneath the wings forming single generally smooth surfaced fore tunnel which extends generally entirely from larboard to starboard of said forward bottom portion, the wings smoothly narrowing aft of amidships and becoming generally horizontal from amidships aft, a top of said hull being of a generally smooth minimal air resistance shape; a fore foil structure mounted to extend downwardly from said fore tunnel; and an aft foil structure mounted to extend downwardly from an aft bottom portion of said hull.
