I can finally get a feel for the size
Everything lines up well!
The bulkheads (minus one) The stock plans call for a three inch drop from the inboard to outboard edge of the top of the bulkheads. I am pretty tall, so I changed this to a one inch drop instead. It will give Grace and me a little more room without altering the lines of the boat too much. Every bit of room counts in a Tiki 21. Tomorrow I will cut the holes for the bunks out of the middle three bulkheads pictured here.
