when all else fails, it's much easier to place the boat in a soft area (grass or sand) and put it on it's side. First check for clearance for the mast. With one person standing to the side of the boat holding the righting line and the other person on the opposite side with the trapeze ring in hand, trapeze person should walk out as far as he can and start to pull down. This will easily roll the boat over on it's side. The person with the trapeze line helps you balance the boat so it doesn't come crashing down. Walk it down with the mast, get to the top, unhook the ring manualy, and step the boat back upright. It's not the ring solution but I bet it's easier than dropping the mast with the sail still hoisted.
