Abstract: The invention provides safety equipment to enable a person to work and move freely around on deck in all weathers while being securely attached to the boat and to enable recovery of a person overboard by other crew members. The equipment comprises a life-line secured along both sides of the boat. At the intermediate attachment points the life-line is secured by latchways which allow a lanyard hook clipped onto the life-line to traverse each such attachment point. When a person goes overboard, the drag force on the lanyard causes the lanyard hook to move to the aft-most stanchion from where the person overboard is towed and removed by other crew members. In another embodiment, the person overboard is towed by pendants at the stern of the boat. A hoist is provided to haul the pendant inboard for recovery of the person overboard.
