I’m repairing a static line that controls the raising and lowering action of the rudder on an older poly touring kayak. It’s simple to envision but hard to execute. The loop is created by what looks like two double fisherman’s knots joining two lengths of rope… creating a long loop with two nice fat “grab” points that are easy references for which side to pull. I tried to replicate the knots with the repair line… but in a double fisherman’s join, the final step is to slide the two knots together — which creates slack on either side, no matter how tightly I wove the knots. Resulting in a sturdy but sloppy loop.
I must be using the wrong knots to join two pieces of rope, right? Is there a knot that allows you to tighten the overall loop of line once the pieces are joined?
