Abstract

A small watercraft having a float on either side of its hull pivotally connected thereto for rotation about a shaft mounted parallel to the direction of movement of the watercraft between a horizontal operative position and a vertical inoperative position taken when the watercraft is stowed away. The floats can be locked in these two positions and in any position as desired between these two positions. Each float is substantially triangular in planar configuration and diverges in going toward the stern of the watercraft. When the watercraft is stationary on the water, the forward end of each float is exposed from the surface of the water; and when the watercraft is planing, each float is exposed in its entirety on the surface of the water.

Claims9

Dependent claims

A small watercraft comprising:

a hull;
propulsion means mounted on said hull;
and
a pair of floats connected to said hull on the port side and the starboard side respectively to increase the stability of the watercraft when at rest, said floats being capable of moving between an operative position in which the floats are substantially horizontal to permit the watercraft to remain at rest or glide on the water and an inoperative position in which they are substantially vertical and stowed away;
said floats each disposed to remain above the surface of the water when the watercraft is gliding with only the forward end of each float exposed above the surface of the water when the watercraft is at rest and loaded to full capacity,
said floats each substantially triangular in planar configuration, diverging in the direction of the stern,
said floats each having an inclined undersurface of substantially uniform width extending obliquely downwardly from the outer edge portion thereof.
