  • Patent number: 4964358
    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.
