of course navies are incredibly important, equal to if not more important than armies. There is a reason why one of the largest contributers to the WW1 was the arms race, not of armies or nukes but of the Dreadnaughts. Also the comparison with Nazi Germany and Rome is inappropriate as they are both in ages where Naval power was not as important (WW2 technologies existed to allow a degree of self sustaining society for some nations eg synthetics for Germany). Vicky is the golden age of the Warship.
Napolian tried to impose a european trade policy not allowing any continental europe countries to trade with the outside world by sea (didnt have much choice the RN kept them at bay and dealt a devastating blow at Trafalger), and look where it got him!. This is the age where imports are the basis for the worlds economy. Spices for instance. Take Austria, not renowned for their fleet admitadly. But where do you think they got their imports from?, They would get it from a sea power and if that sea power is blockaded by a superior navy it has knock on affects across europe.
I hope this is modelled correctly in vicky. Gunboat was the diplomacy of this Naval Age.
