The XL—Series of Dinghy-Lift truly can do double duty. They can be used for lifting an inflatable by either a one point system (i.e. halyard or crane) or by a two-point system (i.e. double davits).DetailsTwo models work for boats with either 3 (XL-3) or 4 (XL-4) internal lifting eyes for attachment, particularly RIBs. Each of the legs has adjustable, stainless buckles to help you balance the load. Strong (3,800 lb. test) 1” nylon webbing is used on all legs of the harness, replacing old fashioned wire legs, but will not corrode or chafe hull. All hardware is stainless steel, including the snap hooks. Safe working load of 450 lbs.
