I have what I think might be a considerably older sunfish. It has a rudder system that someone said was only used until 1972. Who knows. But the main question is like to ask is that, at some point, whether originally or as a mod, someone put a cable bridle on where the mainsheet ties off in the back. The bridle had a swage that creates a loop in the middle, which doesn't seem to be what everyone is using. Most of the sunfish I've seen in videos have a simple length of line that the mainsheet ties to and travels freely across (from port to starboard and back). I'd like to replace the cable with a simple piece of line. How long should it be? Part of the reason I'm asking is because I only realized after someone else pointed out that the tiller is supposed to go underneath that bridle and the one that's on there seems a bit short, and seems to restrict the movement of the tiller, at least at the extremes. I was used to sailing a Hobie 16 before this and we had to pass the tiller around the back of the main sheet and blocks while tacking.
