A French galiot, one of those which entered the composition of the fleet.
This type of very specific and specialized siege shipe is born from the punctual need to have a heavy artillery capable of overcoming terrestrial objectives, including coastal fortifications and Vauban-style citadels. Their curved mortars placed in a central housing of the deck could if necessary also serve in battle, firing heavy incendiary bombs. The name “galiot” is derived from flat-bottomed vessels used by the Dutch. The rig also was specific with a large mast very far back to clear the range of the mortar. Their artillery was completed by small side guns.
