Some observations based on experience building an 11.5' Norwegian Pram;
Beautifully drawn plans came as a pdf to be printed on some US format like 40"x30". I knew I was in for trouble, paper was invented by the Chinese thousands of years ago, and printing invented not long after so it simply must be obsolete in this modern age. I gather they invented some kind of sailing rig too... ;-)
Anyway, while checking out the pdf I noticed that the document if printed at 300 pixels per inch would not result in a printout 40" by 30". The suppliers couldn't understand my concern as they know a lot about Wooden Boats but not much about computer graphics and that 8000 pixels printed at 300 pixels per inch would result in a plan 26.6" high or something like that. In the end I think I edited it myself and printed it on 16 sheets of A4 paper, yes it can be done David T. I used a posterising program free off the internet. The suppliers guaranteed me that two dimensions, one vertical and one horizontal, were printed full size and gave me the exact measurements, so I calibrated to that. If I had gone to my nearest large format printer about 60 miles away I think quite a few expensive sheets of paper and wasted back and forth trips would have ensued. So beware, dashing off to a printer with digital files. And be encouraged that you can do it yourself on A4. Maybe CNC cutting files are immune to issues like this?
Also worth noting; I had my boat in the water for about two-thirds of the cost of a kit from Fyne Boats for the nearest model they have to my boat, and my boat 1) looks better to my eyes and 2) is built like a tank from 8mm Robbins Elite and should last longer than the kit boat. It is glued and screwed clinker construction, built as if using planks of timber.
If you buy a kit or get ply cut, you are stuck with what they sell you (more than full price Robbin's ply, compared to what I got hunting around for sale prices, and repurposing/reusing things). I've nothing against people building kit boats, I just still believe more in doing things yourself. The spirit of the whole project is subtly different, maybe not "better" but probably so for many people.
I still have two sheets of the plans but have lost the pdf, as happens with things digital when you upgrade hardware.
