According to report, operator/owner was fishing 150 ft from shore at Napatree Point, Westerly, RI.  His boat took on a wave that killed the outboard motor and knocked him on his knees. The boat then took on another wave causing it to broach.  The vessel  then washed up into the rocky beach where OPERATOR jumped into the 2' water and was able to unload  all his gear and bring it to shore.  

DEM officer reported that the cause of accident is operator error.  The vessel was too close into shore with the stern facing into the sea.  The boat was in the surf line and which caused it to take on water over the stern causing damage to the engine and then becoming swamped.
