Cog

This ship is a larger, improved version of the coaster, able to make ventures into the open sea. Like the coaster, it is a sailing ship with one or two masts, but the cog employs square sails. It is about 75 to 90 feet long and 20 feet wide. The crew is only 18 to 20 men. There is normally one deck and fore- and sterncastles. The cargo capacities of cogs vary greatly, but the average is 100 to 200 tons.
