Another Outer Island

I decided to chicken out from the Kayak Foundry program for now, and just build another, full-length Outer Island.
I still have the forms from when I bought the original plans, but I decided that they were a little flimsy & troublesome,made on 1/2" CDX plywood, so I traced them onto 3/4 Masonite, and solid pine. This all went well enough, but it brought a quandary to my mind: did I have the forms copied at 95%, or did I just reduce the length? I found nothing on any of the forms that was a specific, measured length, and what really made me wonder was that when I had the bow & stern forms printed at Staples, they didn't fit forms 2 and 16 exactly. After racking my brain for a while, I finally asked Jay Babina for help. He sent me a PDF file of form 16, and my width was exactly what it was supposed to be, however, when I printed it, it wasn't that size! I was finally satisfied that my forms are 100%, but we think Staples' printer is off a little. Its only about 1/8", I think I can work around it.
