D12 stretch charastics

Dont use knots on D12 or V12, and if possible splice the ends and insert a thimble, especially where trap wires connect to the hounds.

Fell of a friends RS700 because he tied a bowline at the top of the trap lines and it cost a new trapeze line and a carbon tiller extension.

My 700 has trapeze wires, I've tried D12 but it was too springy for too long. My 49er had herzog trap lines which were great but they came with the boat so were pre-stretched. My kicker is however v12 which I fitted a year ago now and its going fine thanks to my nicely spliced thimbles.

To be honest it barely takes any longer to splice modern ropes than it does to tie knots in them, and if you dont have a fid or splicing needle, any old bit of wire with a hook on the end will do, assuming it fits down the core of the rope.
