Abstract
Abstract A bailing device for a dinghy comprises a duct having a convergent inlet section, a divergent outlet section, and a low pressure zone. A passage extends between the low pressure zone and the interior of the hull of the dinghy. The device projects downwardly from the hull with the axis of the duct extending fore and aft of the hull. Flow of water thru the duct during movement of the dinghy creates a pressure drop in the low pressure zone whereby water is drawn thru the passage from the hull.

Claim 1
Independent Claim
220 words
In a bailing device for a vessel, a duct assembly defining a duct having a convergent inlet section, a divergent outlet section, and an intermediate low pressure zone, said duct assembly being located within an aperture in the underside of the hull of the vessel, a mounting assembly mounting the duct assembly for movement between an operative position in which the duct is located outwardly of the hull with the axis of the duct lying fore and aft of the hull and an inoperative position in which the duct is retracted within the hull, said mounting assembly comprising mounting means secured in the interior of the hull, and manually operable pivotal lever means linked to the mounting means and the duct assembly, said lever means being located in the interior of the hull and being pivotal from a first stop position in which the duct assembly is in its operative position and a second stop position in which the duct assembly is in its inoperative position, movement of the lever means between its stop positions serving to move the duct assembly between its operative and inoperative positions rectilinearly in a direction transverse to the axis of the duct assembly, and passage means defined within the duct assembly and extending between the low pressure zone and the interior of the hull.
