Model mortar boat Project of 1805. Royal Museums Greenwich ID SLR2702. Object 68661

A note dealing with the use of armour plates for warships mentioned a proposal by Sir William Congreve made in 1805.(1) The Times dated 20 February 1850 described his design for an armoured floating mortar battery which should be shot-proof but never realized. Among his unpublished papers was another suggestion of attaching armour plates to the embrasures of casemates. The catalogue of the Museum of Artillery dating 1865 mentioned

-a model No. 24 (305-1038) of a shot-proof floating battery armed with 4 mortars. Fitted out with hollow iron masts making it possible to cover the whole rigging in a few minutes after she took her station.  Proposed to be used for attacking the French Boulogne flotilla in 1804 (for more details A concise...).

-a model No. 25 (306-1043) of a mortar boat, called the Project, armed with 2-25.4ccm/10” mortars with a rudder at each end to prevent tacking in bombardment, built at Woolwich, England in 1805 (for more details A concise...).

-a model No.26 (307-1039) of a shot-proof mortar boat with a rudder at each end to prevent tacking while bombarding.

The Royal Museums Greenwich owns a model of a shot proof mortar boat which was proposed by Congreve between 1805-1809 according to their website. Her central battery was covered by an angled roof. The hull was pierced with several small gunports for small arms or rockets. Double-ended with rudders at both ends which could be locked in line with the hull to prevent the earlier mentioned tacking. The scale of the model suggest as dimensions 120 x 30 feet.
