Claims11
A watercraft cradle adapted to be mounted on a stern platform of a boat comprising:
- a first cradle member having a plurality of parallel watercraft carriable rollers spaced along the length of the member, a second cradle member having at least one watercraft carriable roller spaced along the length of the second cradle member from the rollers of the first cradle member, the first cradle member attached to the second cradle member to extend lengthwise of the first cradle member, a roller support member carrying a plurality of rollers, a first attachment member adapted to be attached to the platform to removably carry the roller support member at an edge of the platform, independent of and spaced lengthwise of the cradle members, and a plurality of second attachment members adapted to be attached to the platform spaced from the first attachment member to removably secure the first cradle member to the platform.
A watercraft supporting cradle assembly for attachment at the surface of a horizontally extending platform at the stem of a boat comprising a first cradle member having a first frame rotatably supporting a plurality of spaced apart first rollers, the frame including side rails supporting the rollers, frame supporting members affixed to the frame, at least one outrigger arm carried by one of the side rails projecting outwardly of the one side rail and terminating in a watercraft supporting roller positioned to contact an underside of the watercraft, a second frame member movably affixed to the first frame member and including second side rails, at least one additional roller carried by the second frame member parallel to the first rollers, the second frame member movable from and an extended watercraft supporting position to a collapsed storage position, a plurality of securing members affixed to the platform, and a plurality of cooperating securing members carried by the first frame for detachably securing the first frame to the platform.
The cradle of 5 wherein the connection between the first frame and the second frame is a pivotal connection adjacent an end of the first frame whereby the second frame may be rotated from an extended position longitudinally extending from the first frame to a storage position in which the second frame does not substantially extend longitudinally from the first frame.
An auxiliary watercraft cradle adapted to be carried on a platform of a boat comprising:
- first and second frame members alignable longitudinally of each other with each frame member carrying at least one roller member extending transversely, the roller members positioned to cradle and support, an auxiliary watercraft on the frame members, the second frame member being collapsible with respect to the first frame member whereby the first and second frame members may be positioned in extended watercraft support position and in collapsed position, the collapsed position having a longitudinal combined length less than the longitudinal combined length of the first and second frame members when in the extended watercraft supporting position, a third frame member spaced from the first and second frame members and pivotal with respect thereto, the third frame member carrying at least one roller.
