This bridle set-up is the easiest and best way to go. You have to keep everything flexible, as the forces are so big, that even 12mm Dyneema
stretches so that it becomes like a rod! That is my experience on a 35 ft/4.5 ton cat with a 70m2 Code O. With lighter sails
like the gennaker, the forces will probably be lower, as I carry my Code O in 25 knots at 50 degrees relative, sometimes higher.
I found that fixing the prodder in one position, and pulling the sail tack to either bow is a better and easier solution than the movable prodder when using sails
that don't furl.
I have gone back to wire waterstays, with shackles, as i damaged som 3" blocks (standard ones, not hi load)
I made an "horisontal seagull striker" to fit under the tramp, but behind the crossbeam to handle the forces there, as an alternative to using a compression beam like Gideon has made.
Hope this helps
