The fishing vessel Shamrock became disabled in 10 foot  waves with 10 to 20 knot winds off Montauk Point, New York.  The master of the Shamrock reported that a plank in a forward compartment of the vessel’s hull was damaged and allowing water ingress.   The vessel’s pumps could not keep up with the flooding and requested assistance from the Coast Guard.  The Coast Guard dispatched a helicopter and airplane from Cape Cod along with the cutters Tiger Shark and Ridley to the scene.  The vessels were able to reach the Shamrock and provide additional de-watering pumps.   The cutter Tiger Shark escorted the fishing vessel to Montauk, New York.  No reports of injuries to the four crew on board.
