What it is
Man Overboard (MOB) equipment includes devices designed to mark a person's location in the water and assist with recovery. This includes floating MOB poles (tall poles with flags that remain vertical in water), automatic floating lights that activate on water contact, floating strobes, recovery slings or ladders and automatic MOB markers. These devices deploy quickly to mark the overboard position and assist in locating and recovering the person.
What it does
MOB equipment dramatically improves the chances of successful recovery. The tall MOB pole with a flag creates a highly visible marker that points to the person's location even from a distance. Automatic lights and strobes provide visibility at night. Recovery equipment (slings, ladders, or lifting systems) helps get an exhausted, possibly hypothermic person back aboard, which can be the most challenging part of MOB recovery. It’s also recommended to keep a spare halyard rigged on the mast, as it can be used to hoist a person back aboard in a man overboard situation. Together, these tools address the critical phases of marking, locating, and recovering an overboard crew member.
Why it matters
Man overboard recovery success rates are discouragingly low, especially at night or in rough conditions. The faster you can mark the location, the better your chances of finding the person. Once found, recovering an incapacitated person from the water onto a moving boat is extremely difficult without proper equipment. MOB equipment improves success rates in all phases: marking the spot, maintaining visual contact, and completing physical recovery.
General Maintenance
Inspect MOB equipment per manufacturers recommendations or ahead of cruising season. Check that the MOB pole deploys freely and isn't tangled. Test automatic light activation by simulating water contact (use damp cloth, don't submerge). Verify strobe batteries are fresh and lights function. Check that automatic deployment systems (if equipped) haven't been triggered. Inspect recovery equipment for damage or deterioration. Ensure equipment is mounted where it can be deployed in seconds. Replace per manufacturer recommendation.
Common Issues
- Automatic light batteries dying without replacement
- MOB pole becoming tangled in lines or stuck in mounting bracket
- Water sensors on automatic systems corroding or failing
- Crew unfamiliar with deployment location or procedure
- Recovery equipment (ladders, slings) deteriorating from UV exposure
- Flag on MOB pole tearing or fading, reducing visibility
- Flotation losing buoyancy over time
- Automatic deployment systems accidentally triggering
