ABSTRACT:
A marine craft has one or more hulls, each hull being provided with a pair of downwardly-depending walls disposed symmetrically on each side of the longitudinal axis of the hull to define a pair of laterally-spaced tunnels therewith, and so that, in operation of the craft, the walls extend into the water over which the craft travels. The walls are shaped so as to divert and accelerate bow wave water sternwards, through the tunnels, whereby a dynamic lift force is applied to the hull.
