Provided are two drop tubes and two case tubes with each case tube slidably receiving an associated drop tube. A sub-structure below the two drop tubes is formed of two wheels and two side plates. Each side plate is adapted to couple an associated wheel with an associated case tube. A super-structure above the two drop tubes is formed of two wings. Each wing has a C-shaped configuration. The two wings are positionable in a first orientation parallel with the drop tubes. In the first orientation, the two wings are laterally spaced from a vessel when the drop tubes are horizontal for transporting the vessel. The two wings are positionable in a second orientation perpendicular to the drop tubes. In this second orientation, the two wings form a cradle for supporting the vessel thereupon when the drop tubes are vertical for launching and retrieving the vessel.

A system for navigation of an autonomously navigating submersible body during entry into a docking station below the water surface includes a determiner for determining an actual motion vector of the autonomously navigation submersible body in relation to the set motion vector describing the optimum entry direction into the docking station and a calculating unit. The calculating unit serves to determine the deviation between the actual motion vector and the set motion vector to determine control vectors based on the deviation and to thereby control the autonomously navigating submersible body during entry.

An integrated passenger or goods transport system, comprising: a vessel (10) capable of maintaining itself at a fixed height with respect to the floating surface (100), in all conditions of speed and sea state. A system capable of supporting the vessel once it has rested thereon (31). A quick-release coupling system (50) of the pylon (14) and the submerged body (11), in which the propulsion system (20, 22 and 23), the drive system of the wings (12) and the rudder (21), the batteries (19) are contained. A system (70) for recovering and moving the submerged body (11) and the pylon (14) when they are released from the upper part of the vessel (16). This system (70), consisting of an arm having two movements, one in the vertical direction and one in the transverse direction, is also capable of sliding longitudinally on a trolley (71). Once the arm is engaged to the lower part of the vessel, the electrical and hydraulic connections are also restored: this makes it possible to charge the battery, download data for diagnostics and maintenance.
