I'm a little surprised you aren't going a little larger with your ships.  Might be able to add a little speed. 

[snip]

These are analogs of the historic classes from the period. This gives me a nice, solid core of ~16knt battleships for the start of the game. Don't worry, bigger ones will be coming, both Frigates (Im renaming Armored Cruisers dealwithit.gif) and Battleships.

And the first Frigate class. Im calling them Frigates because the White-on-Black paint scheme needs to be on Steel Ships for reasons.
