Just set down the lines for this little dory to see if you could get both plan and profile views on 2 sheets of plywood (you can but it will be tight).
Kind of like this design but would build without centerboard/sailing items. Outboard/Electric would be nice. Mystic Seaport has the original offsets for the 12ft-9in rowing version that I like better but I understand there is very little info given other than offsets.
Gardner had some errors in table of off-sets and stem layout, but he was 90 when he measured the original so going to cut him some slack.
And yes, that is an old school Mutoh drafting machine – took me over 10 years to find reasonable priced one on eBay. Worth the wait.
