Tides of War

recently i began playing ert love it love it!!!
one of my friends is also playing the single player version (same as me).

he showed me the game once and i was surprised to see that his boats (and the ones in the screenshots you can find all over the net) are totally different than mine (colors and stuff).

Is this due to different versions of the game?

You prolly have an older release/demo without the eyecandy made to the ships.
