Hi crusoe
I have a suggestion that i have found works really well on my small boat and i could not see why it could not be scaled up
it is an aluminum prodder that attaches either side of the push pit area (i did not have to drill a single hole) , braced down by a double purchase which leads back to the cockpit and a running clew that also runs back to the cockpit
one of its beauties is that it can be pivoted up when needed and represents little danger to others in berthing situations
it has proved to be enormously strong laterally and handles my generous (for the size of the boat) assy
when necessary to douse under load i fire the clew and retrieve into the cockpit with the leward sheet , i do this solo
although you was not inquiring about assy's i must say mine is just a fantastic short handed sail much more manageable than my symetric
i find i can carry it very close to the wind and dead down wind i am competitive with symmetric's by goose-winging it and when cruising i often drop the main and it runs dd wind just fine
have a look at the photos they explain quiet a bit better than i can ...if you have any questions about the various down haul and clew lines i could detail them better
