I was thinking about the ship UU -- but there are some problems --
Hard to do with some Civs
Mogolian unique ship??
Zulu unique Ship??
but lets give it a try ---
BtS Civs
Babylonian -- an upgraded galley -- not sure what to call it
Dutch -- has one -- needs a unique land unit ??
Ethiopian -- a early galley -- can travel on ocean
http://links.jstor.org/sici?sici=0021-8537(1965)6:2<137:OTPOSV>2.0.CO;2-W
Holy Roman Empire -- river barge -- travel rivers -- provides unit heal, stacks with medic promotion
Khmer -- patrol boats (extra defence in coast, cannot end turn on ocean, replaces guided missle cruiser)
Mayan ??
Native American -- canoe -- improves trade somehow, can travel on rivers
(early caravel that can travel on rivers)
Portuguese -- carrack -- need land UU
Sumerian -- ritual ships -- travel on rivers -- carry missionaries, doubles chance of city converting to religion if in city when missionary tries to spread religion
Warlords Civs
Carthage -- a trimarine counter of some type -- 2 first stikes against trimarines
Celts -- a better transport
http://en.wikipedia.org/wiki/Irish_Shipping_Limited
Korea -- turtle ship -- replaces ship of line -- slow -- but powerful (only coastal)
http://en.wikipedia.org/wiki/Turtle_ship
Ottoman -- upgunned caravel
http://en.wikipedia.org/wiki/Ottoman_Empire#Ottoman_Navy
Viking -- viking ship -- duh -- replaces trimarine -- can carry troops, cannot add to naval combat -- can travel ocean
Zulu ?? -- maybe a modern south african ship
Vanilla Civs
America -- Monitor -- replaces ironclad, 100% defense in coast
Arabs -- dhow travel on river -- heals units when stacked
Aztecs -- ??
China -- junk -- can travel on river -- when stacked with units atacking
crossing river, removes river defense bonus, can carry trebs, which can shoot
http://en.wikipedia.org/wiki/Naval_warfare#From_Wood_and_Wind_to_Steel_and_Steam
Egypt -- guided missle patrol boats -- can carry guided missles -- replaces destroyers
England -- sloop -- replaces caravel -- faster
France -- steath destroyer (more stealthy)
Germany -- pocket battleship replaces battleship, faster and +1 strength, -25% to air attack
Greece -- Athenean trimarine (faster) free navigation
maybe fireship -- replaces privateer? -- very cheap -- blockages one turn then dies -- always dies in combat, but high attack -- low speed compared to SoL and frigate
Inca -- ??
India -- small aircraft carrier (carries 2 fighters) cheaper to build by half
Japan -- aircraft carrier gives auto intercept promotion to based planes
Mali -- ??
MOngolia -- ??
Persia -- Boghammer -- patrol craft, plus 50% in coast attack -- minus 50% defense everywhere
Rome -- quinqueremes that permits combat units to board -- cannot exit except in city, adds 33% of attack and defense to ship combat -- if storm bad weather in area -- ships are lost
Russia -- frigate replacement -- better bombardment
Spain -- War Galleon slower than frigate, as powerful as frigate --
Traveling on river -- any square bounded by river is permittable to navel units
(any square where you can put waterwheel) -- cannot enter hill terrain or mountain terrain
