Caravel: it has only 3

while it's predecessor and upgrade have 4

. It doesn't make sense that more advanced ships are slower. We talk about almost 3 era difference in time!
-
Galleas: same as above. Only 3

.
-
Ironclad: it has only 3

and "Double movement on coast" promotion. I think that this makes no sense. Why can't he just have 5 or 6

(like other units in his upgrade line) without this weird promotion? Not only this is weird but imbalanced: movement bonusses from wonders/englandUA/other sources gives this unit 2 additional

, not 1

. It's strange that this industrial unit can be faster than any other unit in game (except planes). Maybe I don't get the idea, why this unit is slower on oceans (I'd understand if it was ancient unit but this...).
