A boat hoist for launching a boat and for removing it from the water. This hoist includes a scissor-type extensible and retractable arm assembly connected at one end to a support platform for a boat. The entire supporting structure for the hoist is mounted upon the shore and the other end of the scissor assembly is operatively secured to the shore mounted support. The extension of the scissor assembly projects the boat platform over the water and to a prescribed depth therein and the retraction of the arms elevates the boat platform from the water towards the shore support where the boat can be maintained in a docked position free of the water.
