If you look on ebay at the following Heroscape Blue Base Level Mat you will see just what I mean - and many thanks to one of my regular blog readers, SAROE for the heads up on this.
My only problem with using the above mat is that I am thinking with the postage from the US it will make it quite an expensive purchase. I am waiting for an answer from the seller so will take a view on it then. The Heroscape blue tiles will be used in support of the land based collection and are intended for 1/2400th ironclads and the ancient and 16th century galleys in due course. As much of what I envisage will fall in the combined arms/near coastline this is absolutely fine for what I want.
In the meantime the larger hexed Hexon collection will be supporting the 1/4800th scale WW2 collection and possibly the same for WW1 in due course.
