Ok, I'm not an experienced sailor, but hopefully will be one day, this thread has got me thinking, as I am a small person and I will probably struggle with the main on bigger cats.
Wrapping around the hand can affect your mobility in the long run, so why not try something new ?

This is what I'm thinking :
cleat the main loosely so you can add a new line pulling the loose main with it between the cleat and block, this new line can attach to the cleated mainsheet (between the specified points) with a ring or block so you can uncleat whenever you want and release mainsheet through the ring, the purpose of the new line is to have a (really) large diameter so you can handle it better, some sort of a cat mainsheet "leash", I will try this setup but I have to wait a few months...

So guys, as you are much more experienced , what do you think about this ?
