The Sigma Shuttle combines the planar dimension of ships with the longitudinal mobility of a submarine to deliver a new concept in marine transportation. The Sigma Shuttle features a winged triple catamaran design that expands from a slim, underwater tear drop-shaped submarine into a trimaran surface vessel. Steel chains, hinges and hydraulic rods are used to expand or contract the wings to maximize the internal cabin space. Such a design also offers benefits in terms of wing structure strength and stability.
