The offshore rule
requires that a percentage of tethers have either two legs, one no more than 1 M and the other no longer than 2 M, or that the tether be no more than 2 M and have a mid-point loop. But I am not aware of anyone who makes a tether with a mid-point loop.
A few posters have mentioned using daisy chains on smaller boats. Really, that is just a variation on the mid-point loop alternative, with more loops. I am concerned that climbing daisy chains don't have enough stretch, but I think they are keeping them short and elasticity is a separate subject anyway
So how do you use a single
leg with mid-point loop or a daisy chain? I would like to hear actual experiences.
