I think you need to think of the ring as being oriented fore and aft. IE the knot will either be on the port or starboard side of the luff groove. That is because the hook is to the side of the groove. With that in mind, the knot needs to be on the side opposite of the hook.
I just realized that I don't know what I'm talking about. Most of my experience has been on a N5.2 and I'm still waiting for my Blade. So don't pay me any mind. What I will do when I get my new rig is lay it over like Tom had to and work the hook and unhook thing so I better understand how it works.
Tom, did you grab the mast rotator and rotate the mast for all you were worth before trying to unhook the main?
