I am a first time boat builder and building a Shearwater 17 hybrid. I was concerned that everything is square on the boat, so I set up my laser level when I was wiring the panels together. I figured that if the laser hit in the middle of the bottom seam, and a pencil mark at the midpoint of the bulkheads and temp forms I should be fine.
I got very close. But after I did the epoxy tacking of the pieces and removing most of the wires I realize I am a little off. Now as far as I can see, I am never more that 1/4" off the laser line. Is this good, mediocre or bad? I thought before I was glueing that I was within a 1/16", but in the end it seemed to have drifted a bit. (I might not have noticed until my son pointed it out, that I was a bit more that 1/16" off in the bow, possible above the waterline. But like I say, no more than 1/4" and perhaps as little as 1/8" off.
The directions just said to put a couple of sticks on top, and see to it they are parallel. I figure my laser guide would give a better picture.
