Under 46 CFR subchapter M, U.S.-flag towing vessels must have a documented safety management system and emergency procedures that address man-overboard (MOB) situations. Key points include:
- Written procedures: Your Towing Safety Management System (TSMS) or Coast Guard-approved alternative must include clear plans for recovering a person from the water.
- Drills and Training: Crews are required to conduct regular emergency drills, and of the scenarios practiced must be man-overboard recovery. Each crew member should know their role and how to use the equipment.
- Appropriate equipment: Subchapter M doesn’t mandate a specific device; instead it requires that vessels carry suitable lifesaving gear (life rings, lights, ladders, nets, cradles, etc.) that work for the vessel’s design and operations.
- Documentation and inspection: Drill records and safety procedures are reviewed during Coast Guard inspections or third-party audits.
While the regulation doesn’t prescribe one method, inspectors and auditors often want to see that your plan covers scenarios where the person in the water is unconscious or unable to help themselves. Having a safe, practical way to lift an incapacitated person without endangering the crew is an important part of demonstrating compliance and good seamanship.
