RedactedNarrative: The vessel was traveling west after leaving the CT River. The conditions were rough. The operator felt the props clip something. The operator put the vessel in neutral. The forward momentum, wind and waves caused the vessel to become momentarily stationary until a large wave passed and lifted the aft of the vessel, dropping it onto the starboard propeller, shaft and  strut. The struct went through the hull. The vessel began taking on water. The operator issued a May Day call on Channel 16 and responders arrived.  No injuries.
