It is described a craft of variable profile having on its base an arrangement of foldable blades and inflated cisterns on its base which is thus designed to convert the speed craft into a submarine craft of advantageous cylindrical shape and folded blades. This craft is manufactured by assembling lengthwise, in series, the separate compartments; operated by a simple oil engine, it is guided by a hudraulically-controlled directional propulsion system (jet) which combined with hydraulic flow diversion arrangements permits the fluctuation of the speed and the reverse motion of the craft as well as the emergeance-immersion and/or the right-left turn thereof. The proposed craft is provided with a foldable and telescopically-extended snorkel on the top of which a camera with a stepping motor is adapted to replace the convensional submarine periscope. |
