In a boat platform used for putting on wakeboards, it is known to have a fix ed platform. In this invention, 2 small electric motors (similar to car window motors) ar e attached to tracks on either side of the platform moving it up or down. A center arm is used for support. This arm is on a track and has a hook that's attached to a spring a nd held by a pin on the end that locks allowing the platform to go up up; not down. The track has bars for the arm to lock onto every 2 inches. When lowering the platform remove t he pin from the hooks, put the hook in an upright position, replace the pin and lower.
