Thanks Jaime, the best righting line that I have ever used was the 25 foot rope with knots in it. I loopknotted a 2 foot piece of rope around the dolphin striker so when I roll up the line I can just tie it in place. I generally use a bow when its rough because I know I will need it again. you untie, toss over (inside to out) the top hull and sit back. I know that its a pain to have to sit and tie it up again, but I find that you need the rest away.
I have run my boat for years with no jib traveler system except my hands on the windward side and I have never had a problem.
As far as your tiller extention goes, use your imagination. I have seen everything from wooden dowling to the neatest one so far was PVC plumbing tube. EMT tubing from electrical wiring is about the same size as your fibreglass one and about 2 bucks at Home Depot.
