Coaster

Also called a round ship, this is a small merchant ship that hugs the coasts. This is a sailing ship, fitted with two masts and triangular sails. The average size is 60 to 70 feet long and 20 feet wide. The rudder hangs from one side. The crew is 20 to 30 men, and the cargo capacity is about 100 tons. Normally there is only a small sterncastle. A coaster is slow and not tremendously seaworthy, but it can carry large amounts of cargo with smaller crews than galleys.
