I just received the book
The Battle of Trafalgar 1805 by Florian Richter and Peter Dennis. It has "profile models of every ship in both fleets".
On the back is some information about going to the Helion website to find a set of simple rules for a game. The website also has some free downloads.
Helion & Co.
Goto: Browse Title, Series & More>Paper Soldiers>Free Paperboys Downloads on the left.
There is a bunch of interesting looking books there, also.
