Heres a great example why you want to diagram out the dimensions of the front seat per the plans, and then trace something to what youve actually got in the boat before you cut:
Unless youre a very gifted woodworker, of which there are many out there (this is an AMATEUR BLOG, remember?) tracing will be beneficial. The dark black lines are per the plans for the GIS. What you see is what my front seat ended up being to fit in the bow. A little wider up front, very close in the middle, and then wide again in the rear. Ive got a few ideas how this came about, but Im glad I didnt just cut and then try to fit it only to find huge gaps both in the boat and in my wallet as I shelled out 60 bucks for another sheet of ply. This is not a big deal in the end, its truly a slight variation of shape up front, and so it goes.
Heres a few exposures of my beautiful craft as she comes together. Looking good!
