Abstract: The subject of the present invention is direct-propulsion equipment with an internal combustion engine for a boat, in which the engine and the propeller constitute a unit assembly capable of pivoting vertically and horizontally. It consists of a cradle (3) supporting the engine (2), that can pivot near the transom (16) of the boat (1) about a horizontal pivot axis (A2), the engine being coupled to a drive shaft (4) bearing the propeller (5) at its end, this entity being rendered non-deformable by virtue of two semi-circular lateral arms (6) centered on the pivot axis (A2) and each connected by a rear arm (7) to a chair (8) supporting the drive shaft and by a lateral arm (9) to the cradle (3) in order to cross-brace the assembly which is connected to an inverted bracket (15) attached to the inside of the transom (16) and allowing said assembly to rotate about a substantially vertical axis (A1). The invention relates to the industrial and commercial field of boat propulsion unit manufacture and distribution.

Abstract: An apparatus or integrated hull design to stabilize boats with V-shaped hulls. This invention includes a cavity affixed to the inside of the hull confirming to the shape of the inside of the hull. The hull has a step toward the rear of the hull to transition from the V-shape to an essentially flat shape. An opening is provided through the hull and cavity in the step. The cavity extends above water level and is provided with a cover and a vent. The design allows water to enter the cavity enhancing stability when idle or at slow speed and to exit the cavity when at higher speed.

Abstract: A craft having a stabilizing device including a triangular, substantially flat, base floor having a bottom on which the craft floats when at rest and forming the top of the stabilizing device, and a V-shaped hull with sides connected to the flat base floor and extending below the bottom of the floor to form the sides of the stabilizing device, with the flat base floor bottom extending from one side to the other side of the V-shaped hull to define a space which extends completely across the bottom of the floor and is fully open at the rear of the craft so that the space is substantially filled with water when the craft is at rest.
