''A sturdy one-masted merchant ship with a flat bottom.''
A medium difficulty ship, the cog requires fewer sails but more wooden materials than the [[corbita]] and is harder to create. One large advantage it has over the similarly-sized corbita is that the second passenger to board is put into the [[crows crow's nest]], giving them a great view of the surrounding area.
Cogs are great merchant ships as they are a large size, not difficult to build and as a result inexpensive to buy. They are good for long journeys but are impractical for short hops, especially in light winds.
