jake,
F18 looks great, cant wait to sail on it. I did have my foot in the forward footstrap almost the entire time. I didnt have my trap line set up to go to the rear strap, and really didnt need it(or felt comfortable back there).
The bungee was doubled up to make it strong, with a small block on each end. It was completely nside of the rear beam. The rope went into the front beam and tied off. Then you run it to the rear beam where it looped thru the small turning block, then back out of the beam and tie off to the rudder gudgeon. Inside the rear beam there is a stiff piece of bungee that is doubled up, and has a small block on each end. You never see the bungee or the blocks. Only the chicken line itself comes thru the hole in the rear beam cap. You have to play with the length, but thats about it, pretty simple.
