Launched in 1742, Granado was one of the class of bomb vessels developed from the earlier Alderney class.
Bomb vessels such as Granado were the first ships designed to bombard land-based targets from the sea. Mounted on the foredeck was a 13-inch mortar, capable of firing a 200lb bomb some 2 miles. The recoil of the mortars was tremendous and a huge bed of timbers was built to absorb some of the shock. This bed started with 5 enormous riders straddling the keelson, topped with huge fore-and-aft timbers. More transverse timbers went on top and so on until they reached deck level.
The bomb bed took up so much space within the hull that mounting a foremast was impossible. However, the omission of the foremast meant that the centre of effort was well aft in the ship and to compensate enormous headsails were rigged on an overlength bowsprit. Bomb vessels weren't renowned as good sailers, although Granado was considered to be one of the least worst in her class.
This drawing was done for my own amusement, and took a lot longer than I hoped.
