That left 9 with concerns of strengthening which resulted “more glass” solution. I think we are good though as now the entire hull is one size ply. I may clean out Jeff’s 9mm at some point.
And yes on sourcing. The architect is polish. Poland still makes 10mm ply. He offered to supply until the price of shipping and import was raised. It isn’t just US but many other build area only have imperial equivalents available.
