Or Safety harness, is a harness of webbing worn around the chest and shoulders, with a lifeline whose end is attached to a suitable strongpoint on the boat. Ideally the lifeline should be so short that, from its point of attachment, there is insufficient length to allow the wearer to go over the side. But that is not al¬ways possible, and then the only consolation is that you will still be attached to the boat, even if somewhat wet.
