The boat blew up about a mile south of the station and was witnessed by several of us sitting on the front porch on a nice afternoon. These Coasties immediately ran down to the 40-footer (CG-40485) and got underway and extinguished the fire. The burned boaters were transported by private boat to an ambulance. The Coasties towed the hulk back to the station so it wouldn't be a hazard to navigation.
