In comparison to war ship, except the heavier, for their size they appear relatively slow and of course under equiped in number of cannon. Also those trade ships were made so that they are easy to operate with a small crew. For trade with India, if I remember well, they were made to be able to do one trip back and forth, they wouldn't be able to do much more anyways due to the wind being unfavorable during certain season, the hold had to be large but the ship itself didn't have to be especially fast. I know that in case of war they were often requisitionned but you couldn't expect them to fight well against a real war ship, they had more to do with transporting men and ressource than participating in the fight. As for galleon most things I read consider them as primarily war ship, they are certainly heavy since they are used like ship of line and lack speed and the ability to manoeuver fast. On the other hand, I heard more story of them transporting good than participating into fight except being the target of buccaneer, pirates and corsairs. Many captured galleons were even remade when captured to suit piracy activity, for exemple by removing some part of the ship like a deck to make it faster ! For the pictures I think the galleass I found is french, it got quite a lot of the french royal symbol after all. I found the venetian galleon by pure luck so I put it there ! And the Hermione, simply because I saw it (but under construction) some year ago. Like you said it's a typical frigate mainly know for its use in the American Independance, being the ship which transported La Fayette there. Cossacks 3 still has to get a rework of its navy, but it's not for now. First they want to work on the land part before going for the sea. I would certainly love to see them adding more depth to the naval side of the game with trade, more importance put in the mobility and the way you use your ships, the ability to board and capture ennemy ship, to repair damage and even more if possible. Make the sea much more fleshed than they are actually and open sea map, the one we have at the moment often have to much land with player and there is not a lot of place to manoeuver huge fleet that end stuck to 5 to the front and the rest waiting for place to move.
