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.

The load bearing element extends transversely to the plane of the wheel and cooperates in use with the load transfer device, the recesses being evenly spaced around the wheel and adjacent recesses being separated by a projecting part of the wheel.at least one guide member is supported at a peripheral part of the wheel, the wheel and guide member having cooperating relatively rotatable surfaces to allow the wheel to rotate about its axis relative to the guide member with the load bearing element being received, guided and passed in at least one of the recesses while being located with respect to the wheel by the guide member.

Abstract: The safety equipment is used in conjunction with a conventional ski lift system having a series of towers plus turnaround stations, arms extending out from the towers, and single or multiple bogey beams, each having at least two rope support sheaves. A continuous cable, or rope, extends over all of the support sheaves and around the end stations. The safety features include a secondary sheave mounted beside and outward of the primary sheaves with its upper margin below the upper margins of the primary sheaves. If a rope is displaced from the primary sheaves it will fall into the groove on the secondary sheave. To prevent displacement from the secondary sheave, a star wheel is mounted above the sheaves for rotation on a horizontal axis and the radial fingers pass down close to the outside of the secondary sheave and overlap its upper portion. The gap between the sheave and the guard fingers is so small that a rope cannot fall between them.
