RedactedNarrative: V-1 a twin engine cabin cruiser was underway near Ponce Inlet. At or near Channel Marker 7, V-1 left the channel and ran aground causing the port engine to fail. While diagnosing the port engine failure, the starboard engine failed due to a voltage drop. Due to a battery failure neither engine was able to be restarted. Attempts were made to contact help via a cellular telephone as there was no VHF radio aboard the vessel to no avail. Efforts to stop the vessel from exiting the inlet on a fast current by deploying an anchor were unsuccessful. As V-1 drifted out the inlet, it came ashore and grounded on New Smyrna Beach. V-1 was removed by Seatow from the beach.
