Hi Eric. Great to have you on Lumberjocks…someone who designs project instead of relying on a plan from someone else. That boat build sounds like a fun project. I built a 16' hovercraft once,,but I used a plan from Universal Hovercraft ( because I knew nothing about them) and then took it to work and had it redrawn by a girl in the drafting department to my dimensions. I had it for 10 years and it was fun to fly.
I can't wait to see your boat!
Cheers, Jim
