In a marine craft (e.g. large or small ship, aircraft carrier, catamaran or multi-hulled vessel, submarine or aircraft) having retractable hydrofoils of a sufficient size and number positioned from bow to stern, half to port and half to starboard, to support the craft clear of water at speed, each hydrofoil (one of which 7-8 is shown diagrammatically in various positions from 7-8 to 7D-8D in Fig. 3) is carried below the craft by front and rear radial links 5 and 6 respectively hinged on athwartship axes 1, 2, 3, 4, the distance between the upper axes 1, 2 is less than the distance between the rear axes 3, 4 so that as the links swing about their fixed upper axes 1, 2 from the substantially vertical position in which the hydrofoil is in its lowest or working position with maximum angle of attack and therefore producing maximum lift, lower rear axis 4 will rise progressively faster than the lower front axis 3, the hydrofoil folding back and upwards with its inclination becoming progressively less, then nil, then negative. A combined jack and shock absorber 27 may be hinged to the craft and to a crank 30 on the link 5 or 6, e.g. as shown diagrammatically in Fig. 16. Means 73 are provided for adjusting either the front upper axis 1 (as in Fig. 16), or the rear upper axis 2. Various forms of radial links are described, some of which permit telescoping. When fitted on submarines, in addition to their normal near surface use, the hydrofoils may be used for adjustments of depth under water.
