RedactedNarrative: Operator advised he was returning to boat ramp at Pelican Point.  Strong winds from the southwest continually pushing the vessel to the northeast combined with operator inexperience and lack of local knowledge found the vessel in very shallow water.  The propeller grounded into the bottom not allowing the operator to maneuver.  Eventually the motor cut off and the vessel was pushed up onto a submerged rock wall designed to protect from erosion.  The vessel floundered on the wall which produced holes in the keel flooding the vessel.  Upon my arrival I towed the vessel off the rock wall, removed all the occupants, and towed the vessel to Pelican Point ramp where it was put on the trailer.
