Abstract
A kit for converting a small boat, such as a canoe, into a sail boat provides a mast support, leeboards, hiking seats, and a rudder assembly. All of these parts are attached to the boat without the need to permanently alter the boat. The mast assembly provides the option of tilting the mast in the fore and aft direction, and the rudder is mounted along one side of the boat. Both the rudder and the leeboards may be deliberately raised from their normal operating positions to permit the boat to be beached. Also, both the leeboards and the rudder are yieldably biased to their normal operating positions, but pivot upwardly and rearwardly upon colliding with an underwater obstacle, to prevent them from being damaged. After the obstacle has been passed, the leeboards and the rudder resume their normal operating position.
