Don't worry about warpage. I had the same problem with my Patuxent. The kit came with everything nicely taped together, and as soon as you undo the tape the pieces develop a mind of their own. One of the interesting things about the CLC hull is that when all the pieces are wired together, the panels seem to just "pop" into place. Once in place, the panels are slightly bent, which prevents them from resuming their warped shape. The warpage will give you some difficulty in wiring the panels together, but with a little patience you can persevere.

I noticed below you said that if you attach the centers and one end together, you have a 1/2" gap on the other end. Mathematically speaking, if you join the center, and split the difference at the ends, you should have a max difference of 1/4 inch at any point on the panels (+ 1/4 on one end, - 1/4 on the other). This is close enough where you should be able to plane the panels to make them identical. You will need enough clamps to hold the panels together, eliminating the warpage mentioned above. Yes, the warpage will return when you remove the clamps, but deal with one issue at a time.

Once the panels are planed, start to assemble the boat. Depending on how much material you actually remove from the panels, you may have to adjust (trim) the adjacent panels. So wire it together loosely at first, and tighten slowly and evenly. If you need to take it back apart and trim some panels, that should become obvious fairly quick. Remember, if you need to trim a panel, you must also trim its mirror panel on the other side, or it will become asymmetrical.

Good luck,

Ken
