RedactedNarrative: VESSEL #1's ENGINE MADE A NOISE AND SHUT OFF. THE OPERATOR COULD NOT RE-START IT AS IT WAS OVERHEATING. THEY ANCHORED AND CALLED FOR A TOW.  WHEN THE BOAT WAS TOWED BACK TO THE MARINA THE MARINA SAID THE OPERATOR HAD CALLED AND SAID THEY RAN INTO THE SANDY BOTTOM OF THE LAKE.  WHICH WOULD ACCOUNT FOR THE $8,000 IN DAMAGES. HOWEVER, THE OPERATOR EXPLAINED TO THE OFFICER THAT THEY DID NOT HIT ANYTHING.  NO INJURIES.
