I actually started collecting all the official ships for decks and bases to use with the Langtons. This is because I have a wider range of ships. From lowly 12 guns through 24,36, 40, 50, 64, 74, 80,90, 100, 120 rec.

However I did do an experimental game with a fleet of SoG v a fleet of Langtons. The bases are the same size, the ship's obviously different scales but from a picture point of view from SoG to Langton the distance perspective was good. The other way, ok it looked closer. However if you just think the model ship is a representation of the ship itself the scale can be put to the back of your mind. The bases are exactly the same size, ranges the same etc, so no difference only that the SoG ships are 1/1000 and the Langtons 1/1200.
