Autorelease cleat prevents broken rudder

The Clamcleat® CL257 Auto-Release Racing Mini cleat provides the neatest and best solution to the problem of how to lock-down a rudder blade yet allow it to flip-up if it hits the bottom or a solid obstacle in the water. The cleat holds ropes from 4mm to 6mm securely yet will release them immediately when the cleat is overloaded. The cleat is now available in its latest form which includes better rope grip, easier release and a base which can be shaped to fit tubular tillers. It also features the Clamcleat® Racing logo in blue. The CL257 is fitted with an adjustable cam so that the release tension can be set to suit the boat and local conditions. The cam is adjusted until the rudder blade is held down reliably under maximum sailing conditions. The CL257 will then be set so that the least strain is put on the rudder if it hits something solid. https://www.youtube.com/watch?feature=player_embedded&v=P2ssHb4nd4s https://www.clamcleat.com/uploads/zip_files/Auto-Release.zip
