The crew of the Attessa IV contacted Coast Guard Sector San Diego’s Joint Harbor Operations Center watchstanders at approximately 7:50 p.m. reporting a collision with the Prowler approximately nine miles offshore of Imperial Beach.
The collision reportedly resulted in extensive damage to the starboard quarter of the Prowler.

Fox10 News reported Sunday that the man had died.

The Prowler’s remaining ten passengers were transferred to the Attessa IV and taken to San Diego, while the captain remained aboard the Prowler.
