Stay safe and on the deck with these offshore necessities. Harnesses, tethers and jacklines will keep you attached to the boat if you fall overboard, and if placed well keep you from going overboard in the first place. PFD harnesses can be found in inflatable or non-inflatable versions. Tethers and jacklines are made of low stretch and abrasion resistant materials. Some tethers are available with load indicating stitching to indicate when they may need to be replaced. PFD sailing harnesses have been designed for freedom of movement and are highly adjustable to fit comfortably over foul weather gear or sailing clothes.
