This former 110-foot Navy tugboat was purchased in 1990 by the Miami-Dade Department of Environmental Resources Management for use as an artificial reef. The aged tug was stripped of her engine and fittings and towed by the tug Captain Donald from Jacksonville to Miami in preparation for her scuttling. Approximately five miles southeast of the Fort Pierce Inlet, the 60-foot long Captain Donald began taking on water, which flooded her engine room causing the three crew members to abandon ship and the tugboat quickly sank beneath them. All were rescued without injury. The still floating C-One was eventually towed to Miami following the dramatic and somewhat ironic event. She was sunk in 70-foot off Haulover Inlet in the vicinity of several other artificial reefs. The C-One is straddled by the tug Lady Carmen to the west and the tug White Coast to the east. The two sections of the 155-foot freighter Conception can be found less than 200 feet to the north. Additionally, a 90-foot barge and numerous concrete modules lie a short distance to the southeast.
