My hand isn't steady enough for that!
The painted ports and the black line under them were made on the compute,r and printed onto good quality writing paper that was stuck on the hull. The red was sprayed on and the black bulwarks, and grey part of the hull were hand painted using water-based acrylic. The delicate part was painting the grey to meet the black line under the ports, without going over it, and the red underwater area the same. The bulwark panels were also made using the computer, as well as the portholes on forecastle and poop.
