Giving every civ a land UU and a naval UU wouldn't make sense IMO.There are some civs which haven't really accomplished anything on the sea, other civs which had also huge fleets but had nothing to distinguish themselves from other civs.Except for Portugal,Netherlands,Vikings,England i can't see any other civ which could get a naval UU.Afterall UU are meant to be units which are representative of a civ.
Portugal,Netherlands,Vikings,England
That list should be expanded to include Korea, America, Germany, and Japan.
-Korea had some mean ironclads as early as the 1400's. That's early (they were, obviously, not steam powered).
-The USA was actually a British ship factory prior to the revolutionary war. A whole motherload of British shipwrights came to the US to design and build Frigates for the Royal navy. As a result, the USA had some pretty hotsy-totsy merchant ships right from the start. We also had some very nice facilities with which to build a military fleet soon after independence.
Enter: USS
United States, USS
Constellation, and USS
Constitution.
These were fine, strong, double decker 44 gunners that were as proud as any in the Royal Navy. I think the US navy has more than earned a place in the annals of naval history. That's not even taking account the "Second to None" policy that we have today.

-Germany.
Don't ever forget the U-Boats. They raised hell in the waters all around Europe, nearly starving London. In fact, it really wasn't until US Destroyer Division 8 arrived in Queenstown, Ireland that the U-boats were tamed at all.
-Japan
I shouldn't even have to elaborate on this one. The japanese battleships of WWII were colossal and quite powerful. (Yamato, anyone?)
[Yamoto is actually a
class of battleship, of which there were three, I believe]
Korea could have a unique ship -- Turtle Ship. These were the earliest ironclad warships, powered solely by oars. It would have a very high strength, require iron and saltpeter, but be quite slow.
Whoops, Nice nice. You beat me to it but yes.
