A floating, nonsubmersible nautical craft has a hull provided with portholes for observation of the underwater medium. It is buoyed and stabilized, and its draft can be varied. The hull and the apparatus by which it is buoyed and stabilized have a modular structure in transverse sections. The hull is generally tubular in shape, flattened laterally, with a horizontal main axis, with a succession of portholes on each of its longitudinal flanks.

Floating, nonsubmersible nautical craft comprising a partially immersed hull, intended for the accommodation of passengers, closed over all, provided at the top with means of access normally in constant communication with the atmosphere, and portholes for observation of the underwater medium, further comprising means of stabilization and buoyancy separate from the hull and means for varying the draft, means of propulsion and a pilot station, the hull and means of stabilization and buoyancy have a modular structure in transverse section, the hull being of generally tubular shape, flattened laterally, with a horizontal main axis having a succession of portholes on each of its longitudinal flanks, the means of stabilization and buoyancy having, in vertical, transverse cross section, the general form of a flat, inverted U and comprising floats movable between two extreme positions, one being low, in which floats are oriented downward, and the other high, in which floats are oriented at least substantially horizontally, characterized by the fact that the means of stabilization and buoyancy includes a chest having, in transverse cross section, the general form of a pentagon limited by an upper side, an outer longitudinal side, an inner lower side and an outer lower side, the latter two defining a lower edge situated substantially at the level of the upper longitudinal border of portholes.
