RedactedNarrative: Operator stated he left Carrabelle, FL on Tuesday,18 July 2017 at noon and was headed to Gulfport, MS.  While off the coast of Alabama, approximately five and one half miles south of Gulf Shores, he hit a squall which produced waves big enough to strike his vessel and tear the motor from it''s mounts.  
  
  He advised he got caught in the trough which rolled his sailboat almost 180 degrees from starboard to port and back.  He maneuvered into the waves and took them head on, causing the vessel to crash down several times.  He advised he heard a strange sound, ,which turned out to be the motor pulley rubbing against the door covering the motor access.  When he opened the access he had smoke pour out which prompted him to dump two fire extinguishers into the motor compartment.  The displacement of the motor also created a void in the shaft log allowing water to flood the hull. 
  
  Operator called 911 and I responded with Trooper.  The USCG also responded from Dauphin Island.  Upon arriving on scene the operator advised the fire was out and he needed a tow.  The USCG called Sea Tow as the operator was a member.  While being towed, operator had to call tow vessel to stop and allow to dewater.  The vessel was towed to Pensacola Shipyard and hauled out.
  
  07/22/2017   Preliminary subsequent examination showed some burned wires, diesel fuel in the bilge, water coolant lines disconnected, and the exhaust line disconnected.  Motor had dislodged from its mounts and shoved forward against the bulkhead.  The motor cover showed sign of the pulley wearing a hole in it as it was rubbing against it while spinning.  The main battery Perko switch had also melted, sending errant electricity throughout the electronics.  Batteries were disconnected by the owner.  A surveyor was contacted and I am awaiting results for an accurate damage cost.
