I made a righting pole myself in 96, based on a design I saw on a N5.5 uni.

After a while spent sideways on Tres Palacios Bay between races "testing" the first version unsuccesfully, my second version was successful because of two important improvements.

1. Stronger attachment point of pole to front beam between dolphin striker & tramp. I used two pieces angle-iron (aluminum) of fairly thick stock mounted to beam, with 3/16 diam clevis pin as swivel joint through the pole.

2. Second set of lines/wires to midpoint of pole. With lines only at end of pole, the middle of pole bends down when you're in the middle of it, or upwards when you're at end, past line that keeps pole in place. lines to middle of pole prevent excess bend, allow lighter x-section to be used successfully
