Carronade and mounting, c 1795.
© Science Museum / Science & Society Picture Library
Sketch. Carronades are the carriages on which ships' guns are mounted. These carronade slides are fitted on the 'inside principle'. They are pivoted inside the hull, so that the gun can be stowed against the ship's side and the deck underneath it can be cleaned. The gun is also better protected from enemy fire than those used up until the mid 1790s, which had only a very limited traverse.
