ABSTRACT:
A hydrostatically releasable coupling assembly for releasably securing a buoyant object to a vessel with a lashing strap. The coupling assembly includes a pair of lashing plates, a cooperative latching mechanism carried by the lashing plates for releasably coupling the lashing plates together and a composite plunger assembly coupled to one of the lashing plates for movement between a release position and a locking position. The plunger assembly has a first diameter portion shaped for release of the latching mechanism for movement from an engaged position to a disengaged position when the plunger assembly is in the release position, and a second diameter portion formed of plastic and shaped to retain the latching mechanism in an engaged position when the plunger assembly is in the locking position. The plunger assembly also includes an intermediate metal portion between the first diameter portion and the second diameter portion for substantially minimizing contact between the latching mechanism and the second diameter portion when the latching mechanism is disengaged.
