The Sailors Leash: Single or Double? With Elastic or Without?
Once youve settled on the types of clips you want on your tether, the next choice is the webbing construction. Currently, there are two main types of tethers: single tethers with one hook at each end; or double tethers, with two legs and three hooks. Double tethers have an extra clip, usually attached to a short leg at the mid-point of the tether, that shortens the length to about 3 feet.
