We invented the caravels and for a long while we were the only ones to have them... and we also were the first ones to put cannons in ocean going vessels ( in the time of João II ).
In fact , most of the first Portuguese actions in the Indian Ocean were made with basis in caravels ( only later the
Naus ( the thing that firaxis called carracks

Carracks were a general half cargo half war ship that was common in all europe during the XVI... a
Nau was the portuguese refined model ) and the Galleons ( that were warships in genesis... only later the spaniards decided to make high cargo galleons for their silver routes ) entered in play ). The high point of the use of caravels in sea fight was in 1503-04 in Cochim were Duarte Pacheco, with a force of roughly 150 portuguese ( the fattened crew of 4 caravels... normally every caravel had 20-30 crew elements ) and a number between 300 and 1000 Cochim inhabitants defended victouriously against a force of Calicut ( a state that had bad relations with the Portuguese since they arrived there ) that had a 1 per 50 superiority in number of soldiers and 1 per 80 on ships

....
I think that Firaxis wanted a class of scout ships to make the Intercontinental contact possible ,but without possibility of warfare. They decided to it caravel... a bad choice IMHO. And about the Portuguese UU... or they put it earlier in the tech tree ( Compass? ) or give them bombarding ability ( as caravels, Carracks and
Naus certainly had in RL ... I remember a story were 2 Portuguese caravels with cannons ( some of the first ever made ) captured 40 + spanish caravels without cannons ( that were trying to expel the portuguese from their African
Feitorias ) just by bombarding them) ... The game carracks are both useless in warfare and a complete (bad) Fiction in RL terms....
P.S. Sorry for the long rant, but I have a naval historian friend , and he loves the Portuguese naval history of that time ( I do too but he is far worse than me... ). As he offered me a brief history of the Portuguese Naval warfare ( with 6 volumes so far and only covers 500 years

) I decided to give it some use
