In those days when the outbreak of the [[World War I|Great War]] was anticipated, Torres designed a transport ship intended to accompany fleets. On 30 July 1913, he patented the "Buque campamento" ("Camp-Vessel"),<ref name="Patentes1LTQ">''[https://books.google.com/books?id=hz6IUtukL48C&pg=PA55 Un nuevo tipo de buque denominado Buque campamento],'' ''Patentes de invención de Don Leonardo Torres Quevedo'', pp. 55–58, España Registro de la Propiedad Industrial, 1988. ISBN 84-86857-50-3</ref> an [[airship]] carrier with a [[mooring mast]] and a hold large enough to house up to two inflated units, and [[hydrogen]] cylinders. He had thought of the possibility of combining aeronautics with the navy in this way, offering his patent to [[Vickers Limited]], although the conglomerate did not show interest in the project. Negotiations continued, and Torres reached Admiral [[Reginald Bacon]], who, on 17 March 1914, wrote from the [[Coventry Ordnance Works]] that "the experience of the Navy has invariably been that any auxiliary craft carried on board ship are of very little real service". A few years later, in 1922, the [[Spanish Navy]] would construct a real airship carrier, the ''[[Spanish seaplane carrier Dédalo|Dédalo]]'', to be used in the [[Rif War|war against Morocco]].<ref name="Redondo2018">Francisco A.

In 1916 Torres patented in Spain a new kind of ship, a multihull steel vessel which received the name of "Binave" ("Twin Ship").<ref name="Patentes2LTQ">''[https://books.google.com/books?id=hz6IUtukL48C&pg=PA75 Un nuevo tipo de embarcación que se denominará Binave],'' ''Patentes de invención de Don Leonardo Torres Quevedo'', pp. 75–80, España Registro de la Propiedad Industrial, 1988. ISBN 84-86857-50-3</ref> He applied for the patent of the Binave in the United Kingdom with the name "Improvements in Ships" in 1917,<ref>Torres Quevedo, Leonardo, "[https://worldwide.espacenet.com/patent/search/family/032241436/publication/GB111672A?q=pn%3DGB111672A GB111672A Improvements in Ships.]", ''Espacenet'', 23 November 1917.</ref> and it was built by the [[Euskalduna]] company in Bilbao in 1918, with several test departures such as the successful round trip to [[Santoña]] on 28 September. The tests would be resumed in 1919, obtaining the certificate of implementation of the patent on 12 November of that year. The design introduces new features, including two 30 HP [[Hispano-Suiza]] marine engines, and the ability to modify its configuration when sailing, positioning two [[rudder]]s at the stern of each [[Float (nautical)|float]], and placing the propellers [[aft]] too. As a result of the experience acquired in the tests, to improve stability in 1920 it was considered appropriate to add a lower [[keel]] to each of the floats proposed in the patent, making it similar to modern [[catamaran]]s, whose development would become widespread from the 1990s onwards.<ref name="FernándezRedondo2022">Rodrigo Pérez Fernández.
