The kaholo 12-6 plans call for 2 full sheets of 3mm okoume. I just had a neighbor GIVE! me some unused leftover sheets but one is 3mm and one is 4mm. I can't fine reference to what parts are made with what thickness. Just wondering if the SUP can be built by substituting the 4mm piece for the second 3mm piece. My guess would be no since I bet the two 3mm pieces need to be scarfed together to get to length. The plans also call for a half-sheet of 4mm and my neighbor also gave me a partially used piece of 4mm that will cover those parts. Even if it won't work and I need to buy a second 3mm piece it's not a bad surprise on a Sunday!
Thanks for any advice. Patrick
