Mike, nice job!
Now, a question, I have zero boat building experience or knowledge, so when you lay up the foam strips onto the frame, what type of "glue" do you use to:
1. attach the strips to the frame and
2. attach the strips to each other on their edges?
And if the original plans called for 3mm ply strips, was the foam a newer, better option now available but not back when the plans were first developed? Is the foam lighter, cheaper, and/or easier to work with than 3mm ply strips?
