Scale: 1:48. A full hull model of a coca-type sailing vessel (circa 1450), for transporting cargo. The model is decked, equipped and rigged with a square sail set on a single mast. It is complete with crew, who provide an idea of scale.

This is a reconstruction made in the Museum in 1968 and is based on the original 15th-century model of a ship which originally hung in a church at Mataro, near Barcelona. The original is the only known contemporary model of a 15th-century ship and is now part of the collections in the Prins Hendrik Maritime Museum, Rotterdam.

It is typical of the larger type of medieval European trading vessels and measured 53 feet in length by 26 feet in the beam, with an approximate tonnage of 80 burden. These ships could also be used for fighting when required. Bowmen manned the fore and after castles and the large top at the head of the mast. Notable features include the carvel flush planking with the heavy supporting wales and vertical rubbing timbers. The deck beams protrude through the side of the hull and it is steered by a rudder mounted on the stern post, which had displaced the steering oar used over the side since the 12th century.
