Prior to starting, I dug through all my references on the three ships. Using plans and stated dimensions, I made a card-stock master of each ship's plan. I then traced them onto the appropriate sheets of balsa. I used a combination of 1/8". 1/16", and 1/32". GALENA used 2x1/8", CUMBERLAND 1X1/16" AND 1X1/8, with another 1x1/8 traced for the bulwarks. I used the master to trace a regular sized hull piece, and then I traced another outline about 1/16" inside of that. For these CUMBERLAND AND CLYDE, the bulwarks will be cut as a single piece all the way around. Since GALENA has those odd angled sides, I'll wait until she is sanded and then take an honest measurement for her bulwarks.
