The popular Lifesling2 has been upgraded for use on larger recreational and commercial vessels. The flotation collar has 21lb. of buoyancy and can be towed to an overboard crew member rather than the crew member having to swim to it. It also can be used as a lifting sling if your crew member needs help out of the water. Added features include a longer 150' retrieval line for larger boats, stainless D-rings which help facilitate lifting the person out of the water, 2"W SOLAS reflecting tape for increased visibility at night and a rugged, UV-resistant, fiberglass case, which includes graphics illustrating the instructions for recovering a person in the water.United States Coast Guard approved for both recreational and commercial vessels.
