Light ships

(current with version 1.1)

The little brother of the big ships has the same good naval tech multiplier as its sibling - but the hull size and the amount of cannons are not quite up to par. Thankfully, they are twice as fast, and are useful for speeding ahead of a retreating enemy and ping-ponging them for additional victories - much like cavalry.

Type	Naval Tech Level	Approx. Date	Hull Size	Cannons	Speed
Barque	2	1475	10	15	10
Early Frigate	15	1585	20	20	10

Galleys

(current with version 1.1)

This ship type starts off in 1453 as the best "bang for your buck" in inland seas, such as the Mediterranean and the Baltic Sea thanks to its Naval tech shock multiplier, but this advantage wears off fast, and by naval tech 11 the other ship types' multipliers are already significantly better.

Galleys get a +1 bonus to damage in inland seas, and a -2 penalty during naval battles on the high seas.

Transport

(current with version 1.1)

The basic naval ship type to move land forces over seas (colonists find their own method of getting across the ocean). In the early game Cogs[1] are the main ship type used for transport. These ships can lift one regiment at a time, whether they are full strength or not. (If you have three regiments of only 300 men each you will still need 3 transports to carry them all at once.)

Flyte	6	1498	22	4	5
Merchantmen	17	1610	24	8	5
