I've got it now. I can't really explain my confusion but it had to do with the anchor points for the sheet. Consider it sorted.
It really is a great system. In many ways vastly superior to the standard system you see on most older boats .(4:1 purchase with a jaw jammer).
When we had Raven re rigged I did'nt redo the mainsheet system other than to add more purchase. I've always regretted that but at the time the option seemed to be going forward then aft to a single winch which layout I didn't like at all.
Have been discussing the 'Admiral's Cup' system elsewhere and am thinking about redoing the Womboat's setup even though it means buying and installing two new self tailors. Would prefer to stay with a system similar to what we have now but I loath the ratchet blocks we now have.
Valiente - yep the G Boat is a wow to sail but yes it all happens far to quickly for an old fart like me.
