: Time to commit. I've measured, cut, planed, aligned, stitched, aligned,
: checked, eyeballed and, to the best of my eyes, it looks straight. How
: much error can there be in the hull before you notice it in the water?
: What is considered the most important measurement and how do I sleep at
: night after putting down the epoxy and glass knowing my work is 'straight
: enough'?
: I've read about taking out the twist using winding sticks but, that just
: doesn't seem to be enough to ensure it's right. Am I being too precise
: with this or is there other ways to make sure you're straight?
: Thanks much for any help.
: PS The hull is the Guillemot S&G.

I don't blame you for being concerned ,this is a critical step and I remember going nuts myself at that point.When I stitched my Pax 18 I built a simple crossbar frame on to the 2 sawhorses and screwed and wired the sheer clamps to it.With the crossbars level I could run a spirit level along the full lenghth of the hull and twist and adjust the whole hull.There was a very slight twist at the tail that persisted so I screwed a stick to the sheer clamps near the back and tied one end to the ceiling and the other end pulled down to the floor to get rid of the twist.Then I glassed ,filleted and epoxied the inside and froze it straight.I also checked the ends with a plumb bob for twist.
I was a little anal at that point but now that the boat is nearing completion I feel good that I'm sanding my butt of on a nice straight hull.
Sounds like you will figure it out in the end so glass away.
