Frank O’Brien, 55, was last seen on April 4, 2023, aboard the 44-foot vessel Ocean Bound while sailing from Mazatlán, Mexico, to San Diego, California. He was traveling with his wife Kerry O’Brien and a friend, William Gross. The group planned to stop in Cabo San Lucas on April 6, but there is no record of the boat arriving there.

Extensive searches by the U.S. Coast Guard and the Mexican Navy turned up no trace of the vessel or its passengers, and their fate remains unknown. Few other details about the voyage or the boat’s final movements are available.

If anyone has information about the Ocean Bound, its route between Mazatlán and Cabo San Lucas, or sightings of the vessel after April 4, 2023, please share what is known.
