Hi Ivan
I like your way to calculate the approximate material costs, thanks.?
Building time is more difficult. Again, use it for comparing.?
Most important, buy the best jigsaw and sander you can afford?
These two can make the biggest difference in the construction time.
Many builders in speed, newcomers would have CNC machine parts cut. Special for the bulkheads.
But this is just the easy part. Lofting for U-section hulls is a bit difficult, but surely not for
chine hulls like all my designs. No difference in the trapezoidal, asymmetric, or multi-chine designs.
Before you have transported your plywood to the CNC shop and collected the cut pieces you have loft and cut out (for example) your bulkheads.
Not talking about the costs you safe when you do it bt yourself
More important is to use the right tools. A very good quality jigsaw and a very good sander. Best a slow-turning, big radius sander.
It is not funny and time-consuming when the Epoxy gets thermoplastic again clocked sanding paper.?
