So I determined that I would tackle this new build with a degree of accuracy and precision that I've never used before. Instead of 9 foot and 3 iddy biddys, it would be 9' 3/32's. I went out and bought the incra system rulers, 5mm pencil, new glasses so I can see. But then it occurs to me that damn near everything you measure on a boat is going to be way longer than an incra ruler. Like how else do you measure 9 foot something except with a tape measure. And we all know how accurate a tape measure is. So how do you guys make measurements that are long accurate, and precise?
