I searched high and low for some official game mats. All sold out, or the asking prices are extreme. There were some print on demand options, but with shipping came out to almost $80 for a 36x36.
After about an hour I come across the Mat for Armada for $50.99. I figured it was a steal for a 120cmx120cm , roughly 47"x47". There are a few in stock at miniature market. This is just a heads up for anyone else looking for a nice looking mat. I am not familiar with Armada by Mantic, but it reminded me a lot of Dreadfleet by GW.

Are there other gaming systems in the age of sail that make nice terrain pieces? neoprene overlays? for use in Sails of Glory.
