The invention relates to a support and propulsion system for a ship with surface action and lateral keels. Such a ship is capable either of navigation on its hull, or navigation on an air cushion, corresponding to different water line levels A-A, B-B. According to the invention, there is provided, in each of the lateral hulls 1, 2 of the ship, at least one assembly comprising: an engine, installed at a fixed station inside the hull; a transmission box 20 comprising an inlet shaft driven by the engine, and two output shafts 30, 40, as well as clutch means 21, 22 for alternately connecting one or other of the two output shafts to the input shaft, these means being actuated on the basis of the navigation condition of the ship; a pressurised air generator 31, driven by the first output shaft; a marine propulsion screw 44, driven by the second output shaft, this screw being submerged during navigation on the hull and being out of the water during navigation on an air cushion. L'INVENTION CONCERNE UN SYSTEME DE SUSTENTATION ET DE PROPULSION POUR UN NAVIRE A EFFET DE SURFACE A QUILLES LATERALES. UN TEL NAVIRE EST SUSCEPTIBLE SOIT D'UNE NAVIGATION SUR COQUE, SOIT D'UNE NAVIGATION SUR COUSSIN D'AIR, CORRESPONDANT A DES NIVEAUX DE FLOTTAISON A-A, B-B DIFFERENTS. SELON L'INVENTION, IL EST PREVU, DANS CHACUNE DES COQUES LATERALES 1, 2 DU NAVIRE, AU MOINS UN ENSEMBLE COMPORTANT: UN MOTEUR, INSTALLE A POSTE FIXE A L'INTERIEUR DE LA COQUE; UNE BOITE DE TRANSMISSION 20 COMPORTANT UN ARBRE D'ENTREE ENTRAINE PAR LE MOTEUR, ET DEUX ARBRES DE SORTIE 30, 40, AINSI QUE DES MOYENS EMBRAYEURS 21, 22, POUR ACCOUPLER ALTERNATIVEMENT L'UN OU L'AUTRE DES DEUX ARBRES DE SORTIE A L'ARBRE D'ENTREE, CES MOYENS ETANT ACTIONNES EN FONCTION DE LA CONDITION DE NAVIGATION DU NAVIRE; UN GENERATEUR D'AIR SOUS PRESSION 31, ENTRAINE PAR LE PREMIER ARBRE DE SORTIE; UNE HELICE DE PROPULSION MARINE 44, ENTRAINEE PAR LE SECOND ARBRE DE SORTIE, CETTE HELICE ETANT IMMERGEE EN NAVIGATION SUR COQUE ET EMERGEE EN NAVIGATION SUR COUSSIN D'AIR.
