Re: M-20 Scow - Main Halyard
I'd have someone look at the mast and determine if it needs to be repaired. That is significant damage.
If there is a loop in the halyard it was probably adjusted with a small purchase system with a hook at the end. Put the hook in the loop and tighten the purchase.
I don't see the shark teeth cleat you're refering too?
