Abstract
A boat is fitted with retractable wheels which can pivot between an extended land position and a retracted water position. A slot is formed in the hull of the boat. A housing sealing engages about the slot to prevent water entering the boat through the slot. The housing supports a pivot. An arm member is connected to the pivot and a wheel is connected to the arm member. The arm member can pivot through the slot between the wheel retracted and wheel extended positions.
Claims19
A watercraft with retractable wheels, the watercraft having a hull, a slot extending through the hull, and an arm member supporting a wheel, the arm member extending through the slot and being pivotable between a wheel retracted position and a wheel extended position.
The watercraft as claimed in any one of the preceding claims including a towing hitch.
The watercraft as claimed in any one of the preceding claims including an abutment member extending out from the arm member for abutting an underside of the watercraft in the wheel extended position to thereby support the watercraft whilst travelling on land.
The watercraft as claimed in any one of the preceding claims wherein the housing comprises first and second spaced apart plates receiving the first portion of the arm member therebetween wherein the abutment member and the second portion of the arm member are positioned outside the hull.
The watercraft as claimed in any one of the preceding claims, including a stub axle assembly to which the ground contact wheel is fastened, the stub axle assembly being fastened to the distal end of the second portion of the arm member.
The watercraft as claimed in any one of the preceding claims, including a metal frame disposed within the hull, the frame including a leading member protruding through a forward portion of the hull for attachment of a towing arrangement thereto.

- a wheel;
- an arm member having an outer end and an inner end, the wheel being rotatably attached to the outer end of the arm member;
- a housing which has an open bottom, a pair of opposed sidewalls, one end of the sidewalls being interconnected by an end wall, the other end of the sidewalls being open;
- a pivot in the housing, the inner end of the arm member being pivotally attached to the pivot;
- the arm member being pivotable between a wheel retracted position wherein the arm member extends through the other open end of the sidewalls and a wheel extended position where the arm member extends through the open bottom of the housing;
- the housing positioned with the open bottom sealed about an open slot in the boat hull and the open end of the sidewall sealable about a slot through the transom.
