Abstract

A small boat or dinghy rigging mechanism is provided advantageously designed to permit the expeditious recovery, hoisting and stowing of a small boat or dinghy in an upright position at the stern of a main vessel. The apparatus of the invention is devised to be readily detached from the main vessel and stowed so that any unsightly presence of the equipment when it is not being used is obviated. The rigger equipment may be detachably affixed for use directly on the transom of a vessel or adapted to be detachably secured at the trailing edge of a platform such as swim platform that is behind the transom. Because the mechanism is devised to dip into the water allowing the small boat or dinghy to be floated into position on the arms of the rigging apparatus, it substantially facilitates the recovery of such craft and obviates any heavy lifting or exertion of the kind frequently encountered by a user in operations of this kind. Also because the dinghy or small boat is recovered while being maintained upright, is supported underneath, stored at the stern of the main vessel and secured in an upright position, the outboard motor or other depending propulsion or steering equipment need not be removed from the dinghy or small craft in order to recover and stow the small craft on the main vessel.
