I need to replace my head ports. Does anyone know of windows which do not open? I own an O'Day 25 and the windows slant leaving water standing in the drain which does not drain and also the windows leak. I have searched for small windows which do not open, but no luck. I also need a new rope to pull my swing keel. I have never seen these ropes which have a length of cable spliced at one end for attaching to the keel.Any advice is appreciated. Thanks.
