Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 288 words
A watercraft comprising an elongate hull, an engine mounted in the forward part of the hull, the cross-section of the hull rearwardly of the engine having a width substantially greater than its depth to provide a craft user with an appreciable upper surface area on which to lay, sit or stand, a propeller shaft extending rearwardly of the engine and located in a housing provided by the hull, a propellor fixedly connected to the rear end of the propellor shaft, handle means connected to the hull by elongate tension means to enable the craft user to grasp the handle means while standing on said upper surface area, means enabling the engine to remain running for at least a limited period of time following inversion of the attitude of the craft, a fuel supply means having a main reservoir for supplying fuel under gravity to the engine carburettor when the hull is correctly afloat, and an auxiliary reservoir disposed below the main reservoir and in communication therewith via a tube depending downwardly therefrOm, the tube being operable to retain fuel in the auxiliary tank when the hull is upside down to enable fuel to be fed under gravity from the auxiliary fuel tank to the carburettor, the main reservoir having a fuel filling opening, a non-vented cap for closing said opening, a bleed valve for venting the main reservoir, and wherein a bleed tube connects the top of the main reservoir with a fuel feed tubing connecting the carburettor to the auxiliary reservoir, and wherein a one-way valve is incorporated into the bleed tube to permit air to bleed from the feed tubing to the main reservoir when the attitude of the craft is corrected from an inverted position.
