Abstract
A tunnel-hulled boat that has a high degree of maneuverability at low and high speeds with decreased hydrodynamic drag is disclosed. The tunnel-hulled boat is maneuverable in shallow water and when proceeding in reverse. The tunnel-hulled boat is comprised of a hull having a generally square-nosed and notched aft and generally concave tunnel disposed from proximate amidships to the aft, with the concavity increasing as the tunnel proceeds aftward. A first set of bevels having increasing diameter extend along either side of the tunnel while a second set of bevels are each disposed within a respective one of the first set of bevels proximate the transom of the boat. A pair of sponsons are attached to the transom on either side of the tunnel.
