How to build your own 28mm ship for tabletop RPG cheap

I recently build a set of 28mm ships for my D&D campaign at sea. I used foam core and made each boat for about $1. The guide provided will build a modular ship that can have up to five different configurations, ranging from a flatboat to fullsize cog. The pictures below are some of the ships I built and I have provided a link to my Ship Construction Guide pdf.
