What makes the Sea Catch so revolutionary? A well-thought-out design that anticipates reality: Heavy sea conditions, corrosive marine environment, quick release kick-back, inadvertent release, and the occasional shock and lock-up of unanticipated overload. Sea Catch is a tough and multi-purpose quick release that combines unique features such as no springs, common shackle connection, multi-directional release capabilities, low friction releasing and a hitch-pin safety lock.
