1. I am not sure on the alingment. Mine are straight to the naked eye but measurements might prove differently.

2. mine has the factory hiking stick, it is really nice just a twist and you can extend it out to almost 8 feet and then collapse it back in the same way. I have heard of guys using the aluminum pool cleaner handles. I have a friend with a H16 that does that. It works well and is only 20 bucks...but I don't know how long it will last.

3. You can order that whole kit to rebuilt the set up, it is cheap and works well. They pop up on ebay from time to time in the buy now section.

4. I want to know the same thing!!! I am having vinyl names made for the hulls and was going to see if I could get another Nacra sign made. If I do I will see if I can get a bunch made.

5. I think people suggest the smaller line for racing because it runs through the block easier. I have upgraded to a larger line because the one I had hurt my hands after a long day on the water. That is really up to you.

You are not to far from me, I am in Norman Ok.
The 5.2 is a blast and tough as nails. Glad to hear the other people sail them.
