Abstract
An inflatable mechanism for attachment to the top of a sailboat mast to counteract turtling (complete rotation of the boat into an inverted position where the mast is pointed straight down into the water) during a capsize. The device functions by producing a torque consisting of the water displacement force and the mast as a lever arm. When the boat tips over on its side during a capsize this torque balances the boat's natural tendency to continue to roll over into an inverted position.
