How does this work? Mast loops for halyard


New Member

I’ve recently obtained a mast that I’m going to put on my butterfly that I’m restoring. It doesn’t have pulley at top of the mast, but two loops. When I run the line and pull the sail it binds and I think I have it set up completely wrong. Any thoughts on how to rig this? I don’t know what type of sail boat it went with.

If anyone can just identify the sailboat this goes too would be appreciated. I can take this to the correct forum, or at least narrow my search. It works if I just hang a pulley from the sail side off of the mast, but I don’t think this was the intended design.

thank you
