Narrative:

While engaged in water practice (idle taxiing) a submerged object was struck. As the possibility of float damage existed, and the adjacent breakwater was steep and rocky, a plow turn to a downwind heading was initiated to get the airplane to a safe, nearby beach. Possibly, because of float damage, the plow turn was not successful and the aircraft struck the rocks at the base of the breakwater. At this time the aircraft was pulled up onto the breakwater for safety, and secured with ropes to keep it from being blown away to deeper water by winds. The coast guard boat arrived about 20-30 mins alter, but left the scene when they confirmed no one was injured and the airplane was not obstructing the boat channel, and was in no danger of doing so. My passenger (an ases student) remained with the aircraft while I went for assistance to remove it to a safe location.

Title: TRAINING FOR ASES RATING. TAXI TRAINING HIT SUBMERGED ROCK.

Narrative: WHILE ENGAGED IN WATER PRACTICE (IDLE TAXIING) A SUBMERGED OBJECT WAS STRUCK. AS THE POSSIBILITY OF FLOAT DAMAGE EXISTED, AND THE ADJACENT BREAKWATER WAS STEEP AND ROCKY, A PLOW TURN TO A DOWNWIND HDG WAS INITIATED TO GET THE AIRPLANE TO A SAFE, NEARBY BEACH. POSSIBLY, BECAUSE OF FLOAT DAMAGE, THE PLOW TURN WAS NOT SUCCESSFUL AND THE ACFT STRUCK THE ROCKS AT THE BASE OF THE BREAKWATER. AT THIS TIME THE ACFT WAS PULLED UP ONTO THE BREAKWATER FOR SAFETY, AND SECURED WITH ROPES TO KEEP IT FROM BEING BLOWN AWAY TO DEEPER WATER BY WINDS. THE COAST GUARD BOAT ARRIVED ABOUT 20-30 MINS ALTER, BUT L THE SCENE WHEN THEY CONFIRMED NO ONE WAS INJURED AND THE AIRPLANE WAS NOT OBSTRUCTING THE BOAT CHANNEL, AND WAS IN NO DANGER OF DOING SO. MY PAX (AN ASES STUDENT) REMAINED WITH THE ACFT WHILE I WENT FOR ASSISTANCE TO REMOVE IT TO A SAFE LOCATION.
