ABSTRACT:
In the mooring of ships, boats and barges to a dock or oil well platform it is necessary to have a line run from the ship or boat or barge to the dock or platform. The line running from the dock or platform to the ship or boat or barge is under tension. This invention is directed to a RELEASEABLE HOOK which, automatically, trips and releases the line when the tension on the line exceeds a predetermined tension. The ship or boat or barge at that time is free to move. The increase in the tension in the line maybe be brought about by rough water or by a wind or other causes. This RELEASEABLE HOOK is a design to trip and release the line without an operator. The tension in the line, when it exceeds a predetermined tension or pressure on the hook, will cause the hook to automatically trip.
