I read an article about improving sail trim. The boat in question had its main sheet fixed to a point on the transom, much like mine. They said that just fitting a simple rope horse across the boat would allow the sail to be pulled flatter. So I have fitted one. Simply holes bored carefully through the coaming by the feet of the boom gallows, and a rope between. Holes sealed with epoxy, and they will be easy to fill if it all doesn't work. It looks like it should, but only sailing will tell. The current BC20 has a main sheet track across the transom. I don't want the expense of that, and it wouldn't work with my boom gallows anyway.
