Back to the Cat - First Bulkheads

The winter project (dinghy build) finished, it is time to direct my thoughts to building the Gypsy Sophia. There was one sheet of 6mm ply left from the cuddy, so I spent an interesting afternoon seeing how many bulkheads I could get out of one sheet of 8' x 4' plywood. The answer = 3. Alas, these are the smallest bulkheads, and the remaining 11 will probably require one sheet of plywood each - unless I can join bits together; a question for the forum I think. Time to save for more wood!
