That link shows a heavily overdesigned righting pole system, and it looks fairly heavy.
a foot of quarter inch prestretch is all you need to connect the pole to the dolfin stricker. the other end of the pole just needs a length of line to tie the pole to the top hull. all that line in the system would only be necessary if you flip often so the pole is pre attached to the windward hull. you could STF for previous posts on this subject.
