At or near each corner of the amphibious equipment is a hollow vertical buoyancy tube 18 or 16, which can be selectively flooded to alter the draft or swung outboard to facilitate entry and pickup of a floating hydrofoil or like craft and then back inboard to grip the hull. Also at each corner are hydraulically driven track pairs 5, working off hydraulic pressure generated on board, tiltable to cope with sea-bed or shore configuration; and individually turnable to manoeuvre or move the equipment when standing on the sea-bed. Tracks 5 are mounted on cylinders 6,7 whereby the effective sea-bed load can be increased i.e. by forcing more of the equipment out of the water than natural buoyancy permits. <IMAGE> |
