A British 74 and 90 (background, with red-colored deck) facing a French 74 and 110 (light blue). All ships have WSIM style ID numbers printed on the quarterdeck. In the full size version they are fairly easy to see on the French ships.
The British 74 next to the French 110. (I really need a closeup of a 120, too :-)
Two partially dismasted 74s (a British and Spanish one) in the process of sinking, with a French 64 and a 44-gun frigate standing by. Sinking ships are relatively rare in WSIM (as in history), but I did a number of them because they provide some interesting variety. Also, we occasionally increased the chances of ships sinking to reduce map congestion in our games, and then we could use quite a few such ships. (Sinking ships don't have ID numbers since they are generic.)
On the left, the Santissima Trinidad, the largest ship of the line during the Napoleonic Wars (rated 130 or 140 guns depending on what sources one reads), sandwiched between a British 74 that has lost its mizzen mast, and a British 100 (could be HMS Victory) with a flagship pennant on its main mast. On the right, two more sinking two-deckers - a Spaniard going down by the bows (this could be used for a 64, 74, or 80), and a British 74 listing to port. (The Santissima Trinidad is wearing an earlier paint scheme AFAIK; according to at least one book I read she wore red and white stripes at Trafalgar, but I decided to go with this more unusual scheme, in part because it was easier for me to produce.)
