Several years ago I made a set of 8 modular terrain boards in 2 x 4 foot size to use in different combinations for a 4 x 6 table.
Four of the boards have water features, two with rivers and two with coasts/shorelines.
When I envisioned having forces for AWI games, I also envisioned having some sort of interesting background scenery that might also lend itself to potential scenarios. I always wanted some kind of naval presence on the tabletop.
In the end I decided on British ships that were anchored just off coast, with transport boats bringing troops and supplies to shore. Would make for a nice backdrop to a game.
I chose a couple smaller ships from Firelock Games' "Blood and Plunder" ranges, the Sloop and the Brigantine. I also picked up one of their longboats to be used as a supply boat.
My thought when getting the two larger ships was they were going to be more impressionistic than strictly realistic. I wanted at least one of them to look like bigger ships of the line or frigates, so I modified the Brigantine so that it had more of the standard square sails on the masts. This was at least an attempt at the ILLUSION that it's a larger ship parked off-shore without it being a larger ship, lol.
Plus they work for the limits of the space and table size I have.
After receiving an enormous amount of excellent information about how sails work and all sorts of technical info. on how they might look when furled vs. unfurled, I went with the furled version of the sails as if the ships were anchored.
I bought a piece of cloth from a hobby site that was labeled simply as "sail cloth" and when I got it realized that essentially it was just a cut piece of generic cotton fabric, maybe muslin I'm not sure. But in any event for a furled sail all it needs to do is look off-whitish and "cloth-like."
Going with the historical advice that sails in the 18th Century would be bundled or gathered rather than rolled, which apparently is a more modern way of furling sails, I just took rectangular pieces of the fabric and folded them back on themselves and glued each layer down as I folded. Ended up with accordion-like bundles that seemed to be convincing enough.
Then I took jute cord and wrapped it around both the sails themselves as well as a couple more around both the mast and the "cross-support" (don't know what the nautical term for those are).
I think they look pretty good for what they're meant to represent.
I kept the paint jobs very low-key. I just wanted them to look like weathered ships that have seen a lot of voyages. I might go back and give more color to the hull but they're pretty good as is for now.
Overall I'm pretty happy with how they turned out. Not highly realistic but visually pleasing enough.
