RedactedNarrative: V1 was heading back to the boat ramp towing another boat when the engine quit, just on the south side of the rock break wall, south of the boat ramp. V1 dropped anchor and tried to restart the boat about 700-800 ft from the rock wall.  The anchor wouldn't hold the boat due to the wind & waves so V1 drifted into the rock wall grounding the vessel.  All individuals put on lifejackets waiting for rescue crews to  take passengers off the vessel, as it was taking on water from the damage to the hull.
