Abstract
A device that mounts onto the front of a kayak to assist in righting the kayak after it rolls over. It consists of a small mast that is attached to a hinged base. An inflatable bag is attached to the top of the mast along with equipment to inflate the bag. A lanyard is attached to the inflation equipment and to the top of the mast. In a rollover, the user pulls the lanyard, which causes the bag to inflate and the mast to rotate 90 degrees. This places the mast perpendicular to the kayak with the inflated bag at the far end of the mast. The inflated bag acts like an outrigger that causes the kayak to roll back upright automatically. In this way, the kayak is turned upright with minimal problems and difficulties for the user.
