UNITS
The following units require a bit more explanation than can be
found in “The Basics” portion of this manual.
NAVAL UNITS
Throughout history, mankind has made great use of the seas.
For millennia fishing boats have harvested the oceans’ bounty.
Trading vessels have carried goods to every corner of the
world. Exploration ships have sought out the oceans’ secrets.
And mighty warships have fought great battles to decide the
fates of nations. In Civilization IV the seas are places of great
opportunity and peril.
Constructing Naval Units
Naval units can be constructed in any city adjacent to a coastal
space.They are built like any other unit – they require specif-
ic technologies (and sometimes resources) to be constructed.
DRYDOCKS
The drydock building increases the speed at which a city con-
structs naval units by 50%. Further, naval units constructed in a
city with a drydock begin the game with 4 experience points.
(You must have the “steel” technology to construct drydocks.)
Moving Naval Units
Some early naval units must remain in coastal spaces or any
water spaces within their builder’s cultural boundaries. These
units can move within other nations’ cultural boundaries if
their civilizations have an Open Borders agreement with those
nations or if they’re at war with them. (See work boat and gal-
leys, pages 126 and 128.)
CROSSING CULTURAL BORDERS
A naval unit cannot enter another civilization’s cultural borders
unless its civilization has an Open Borders agreement with that
civ. Otherwise, such a movement constitutes an act of war.
(Exception: see caravels and submarines, pages 125 and 127.)
Naval Combat
Naval units can only fight other naval units; they cannot attack
land units – though some can “bombard” coastal cities (see page
42). See “Air Units” to learn how naval and air units interact.
