The invention provides a boat for one passenger or more provided with a floating hull (10) and, below said hull, an immersed cabin (11) for passenger(s) and to be entered by a hatchway (12) at the hull-level. The boat can be provided with a pedal propulsion.
The present invention concerns boats or watercrafts in general and more in particular a human-propelled water veicle, especially by pedals, for one passenger or more.
Various kinds of watercrafts with screw propeller, paddle-wheel or the like propulsion driven by an engine or pedal transmission are already known in the art and normally used. Said boats float on the water surface and the passengers get on it while it always and in all cases keeps the emerged position, without the possibility of underwater observation.
On the contrary the object of the present invention is to provide a vehicle in the form of boat or watercraft which is desinged so as to float on the water surface and allow at the same time the navigation and underwater vision for one passenger or more.
For this end, the vehicle according to this invention includes a floating hull and, below said hull, a transparent cabin for one passenger or more to be entered by means of a hatchway at the hull-level, the cabin being immersed and allowing underwater observation and vision in all directions, including the downwards one.
However, more details of the invention will result from the course description which is made by referring to the attached drawings, indicative and not limitative, wherein:
Figures 1 and 2 show respectively a side view and a top plan view of a vehicle according to the invention and pedal-propelled; and Fig. 3 and 4 show two similar views of a motor-propelled boat.
In both the illustrated embodiments, the boat includes a floating hull 10 and below the hull, in order to result immersed, a cabin 11 defined by partially or totally transparent walls. The hull 10 will be appropriately ballasted and sized as well as provided with a hatchway 12 to enter the cabin below.
The cabin 11 is suitably settled to the hull, careened and sized so as to house at least a sitting passenger, preferably two passenger or more placed in side by side or tandem position - see Fig. 3 -.
Besides a direction helm the vehicle can also be provided with a screw propeller or else, with a control shaft 13 which can be driven by at least a passenger placed in the immersed cabin as shown in Fig. 1. As an alternative the vehicle could be provided with an outboard propelling motor 14 as shown in Fig. 3.
In all cases the passenger placed in the immersed cabin can float and make underwater observations either for controls and plottings or entertainment. Nevertheless, other passengers could be placed on the floating hull as it is in a common boat.
Finally it is to be noticed that some wheels 15 can be applied to the hull or the cabin - see Fig. 1 - as a support or prop on the ground in order to make out of water shiftings of the boat easier.
