Just an update:
I ended up calling some riggers out to the boat. The rope/wire halyard had jumped the sheave. They ended up running a new main and genoa
halyard. Once they got up top, they realized that it needed a halyard restrainer as well, to prevent this from happening again. So, they added one.
700 dollars later and I can get my headsail down now...problem is, the UV cover is now ripped up from a storm, because I was not able to properly roll the sail up for a while.
Anyways I read some tutorials online for DIY sail repair, but most of them involve sail tape. Other DIY guides didn't really talk about specifically repairing the UV cover.
Could I just get some thread and run it through the old holes? It's mainly just ripped at the seam...
