A polémiko is a fast and highly maneuvrable warship with four masts, each having three large and two small sails. It has a slender profile with a tall, pointed bow and stern, and a relatively small cargo space on the lower deck.

Shared but spacious quarters are in the two-decked stern, and the small crew (8-12) and army of gunners (3-8) spend most of their time on the open top deck.

Polémiki are usually part of the Espurian? and Marportian? navies, but are sometimes hijacked by pirates (which are then known as peirati) or sold off to merchants who can afford the extra protection (known as mercántiko?).
