Cog

A broad, single-masted vessel with square rigging, high sides and a relatively flat bottom, stable enough to be sea-going but not safe for ocean journeys. The ship has a small castle both fore and aft. These ships are common in the Baltic Sea, where sufficient but controlled winds enable good navigation, while the hull is strengthened against sea ice. They are less practical in the Mediterranean, where the winds are not as strong much of the year or against the heavy winter seas.
