Warships are 100-foot-long ships with a single mast, although oars can also propel it. It has a crew of 60 to 80 rowers. This ship can carry up to 160 soldiers, but not for long distances, since it does not include room for supplies for that many. The warship cannot make sea voyages and sticks to the coast. It is not used for cargo. It moves about 2 1/2 miles per hour when rowed or under sail.
