You could permanently tie that "ladder knot" into your righting line at the perfect length so it will be there when you need it. Why didnt I think of that before now?
Yes, its best to be in the gym, but I have been so tired from sailing hard on day 3 of a regatta that after I swam a long way to catch my boat, my strength was zapped. Thanks to the Tradewinds RC for pulling me up and giving me some water and a rest!
