Abstract: A swim platform is built into a side of a boat, either the port or starboard side. The swim platform is raised and lowered by a mechanism that fits within the side wall of the boat beneath the gunnel. The swim platform is raised when the boat is underway to prevent water intrusion, provide safety, and reduce drag; while the swim platform is lowered, for example, when the boat is anchored for enjoyment of the boaters using the boat.

Abstract: A transom bracket enclosing a hydraulic power cylinder is mounted to the transom of a watercraft. An actuation rod of the power cylinder moves multiple lift arms connected to a platform bracket supporting a platform for supporting a small auxiliary watercraft. Electrical or manual operation of the power cylinder causes the platform bracket to move in a vertical direction either upwards out of the water or downwards into the water. A lock mechanism operated by a lock cylinder locks the lift apparatus in place when not in operation. Grooves on sides of the transom bracket and transversely extended pins connecting the linkage arms provide a downward stop to movement of the lift apparatus.
