Demi-cannon

[2] A full cannon fired a 42-pound shot, but these were discontinued in the 18th century as they were seen as too unwieldy.

Ships featuring demi-cannons included Sovereign of the Seas,[1] Resolution[3] and James, which fought in the Anglo-Dutch naval wars.

Demi-cannons were also used on HMS Stirling Castle, the wreck of which was discovered in the Goodwin Sands.

[4] The barrels of demi-cannon were typically 11 feet (3.4 m) long, had a calibre of 6 inches (150 mm) and could weigh up to 5,600 pounds (2,500 kg).

Though powerful, the naval demi-cannons were inaccurate, except at close range, which allowed warships to cause as much damage as possible.
