Cut out ship from card stock. Then trace to blue board or whatever form you wish to use.
Pick up a hot wire from you local hobby shop. Leave a little to shape on the outside of lines.
Trim to shape.
Pin together, I used toothpicks and then the hot wire to shape more like a Ship. I will look a little rough just using a hot wire don't worry once painted it looks more like wood. I used poster board paint. It is very cheap, picked this up at the hobby shop as well. anyway non-toxic so will not eat the foam board.
Dry brushed some white and blue for the water.
Glue the card stock to the tops of the blue board. trim where needed.
My wife was right keeping them books in the house was a good idea.
Last step is to add plastic sheet laminate. This way you can add spell effects or whatever you wish and protection the paper.
Wife and I have been talking about how to add mast and other things to our ships. Will post that, NEXT is a War ship.
