Boat Explodes and Sinks In Waters Off Sausalito, Occupant Injured A man put out a distress call Sunday evening when the boat he was on in Richardson Bay, near Sausalito, suffered an explosion. The 35-foot vessel, identified by the name Folie Douce, blew up in what the harbormaster has said was likely the result of a leaking propane tank. Rescuers from the Southern Marin Fire Protection District and U.S. Coast Guard responded to the incident, and were able to rescue the man, identified as Mark Culver, before the boat fully sank. Culver has reportedly been hospitalized. The Richardson’s Bay Regional Agency (RBRA) reported on the incident, per KPIX, and it remains unclear whether Culver was the owner of the vessel. The boat was apparently identified as inoperable in a harbor census in 2019, but has been anchored in the bay for some time.
