I've had a i20 for 13 years never had a problem releasing the main, now that I am using another main I can't get it to release in the normal way, pulling the halyard and over rotating the mast. Any ideas. Thanks
Common problem. The tops of the mains are often made just a bit different with the bolt rope closer or farther from the Grommot. I use to tie a bowlon at the top. When I got my new main I had to run the line through the ring and put a stopper knot in the back to that it pulls the ring off the hook.
