Ship of the Cinque Ports, c 1284.
© Science Museum / Science & Society Picture Library
Model (scale approximately 1:48) based on the Seal of Dover in use in 1284. The Seals of the Cinque Ports are almost the only contemporary information available. The ships of the 11th and 12th centuries differed little from Viking longships. As more reliance came to be placed on sail power the vesels were built with increased beam and depth to carry the larger sail. During the 13th century, fore and aftercastles were added to these ships for fighting purposes. This ship was about 75 ft in length and 25 ft wide. The Cinque Ports are first mentioned in an Enlish Royal Charter of 1155. They were five ports (Sandwich, Dover, Hythe, Romney and Hastings) which, in return for certain privileges, guaranteed to provide the Crown with ships in times of national strife or crisis.
