Figure 8 Man Overboard (MOB) Maneuver

Performing a figure 8 man overboard (MOB) maneuver is a critical sailing technique to rescue a person in the water while accounting for wind and drift. Upon shouting “Man Overboard” and deploying flotation devices, immediately assign a crew member to maintain visual contact. To initiate the figure 8, Enhanced Man Overboard (MOB) Recovery Technique: Beam Reach Maneuver

Immediate Actions Upon “Man Overboard!”

  1. Turn to a Beam Reach: Immediately steer the boat to a beam reach (wind perpendicular to the boat). This establishes a controlled point of sail to execute the recovery.
  2. Activate GPS MOB Marker: Press the MOB button on your GPS/MFD to mark the victim’s location.
  3. Assign a Dedicated Spotter: Ensure the spotter keeps eyes on the victim at all times—no exceptions.
  4. Deploy Flotation: Throw a Type IV throwable cushion and additional flotation devices (e.g., cushions) to create a visible “scatter zone” around the victim.
  5. Prepare Recovery Gear: Ready lines, a boat hook, flares, and life-saving equipment.
  6. Radio Communication: Issue a “Mayday” (life-threatening emergency) or “Pan Pan” (urgent but non-life-threatening) call via VHF radio.

Managing Sails

  • Leave Sails As-Is: Avoid trimming sails. Improper trim will slow the boat, which is acceptable since speed away from the victim is not the priority.
  • Exception for Large Sails: If sails are oversized, briefly over-luff them (allow to flap) to reduce speed, but prioritize maintaining course control.

Executing the Beam Reach Maneuver

  • Sail Away 3–5 Boat Lengths: Distance depends on your vessel’s acceleration. Slower boats may turn back sooner; faster boats may need more space (up to 7–8 lengths) to decelerate.
  • Goal: Position the boat to return to the victim at near-stopping speed.

Returning to the Victim

  • Tack/Jibe Promptly: After reaching the designated distance, tack or jibe to head back. Use momentum to glide toward the victim.
  • Prioritize Proximity: Balance the need to decelerate with staying close enough to maintain visual contact. Avoid excessive distance—practice to determine your vessel’s ideal approach.

Key Considerations

  • Boat-Specific Adjustments: Faster boats require longer distances to slow down. Adapt based on your vessel’s handling.
  • Follow Protocols: Use pre-agreed procedures (e.g., scatter zone deployment) to ensure crew coordination.

This method prioritizes quick action, controlled maneuvers, and adaptability to your vessel’s characteristics, maximizing the chances of a safe recovery.
