Abstract

A watercraft (1) comprising a hull (2) and retention means (7, 10, 20, 20a, 20b) to connect a sea scooter (8) and said hull (2) together in such a manner that said sea scooter can at least contribute to the propulsion of said watercraft.

Claims

1. A watercraft (1) comprising a floating hull (2), characterised by comprising retention means (7, 10, 20, 20a, 20b) to connect a sea scooter (8) and said hull (2) together in such a manner that said sea scooter can at least contribute to the propulsion of said watercraft.

2. A watercraft as claimed in claim 1, characterised in that said retention means (7, 10, 20, 20a, 20b) are arranged to connect said hull and said sea scooter together rigidly.

3. A watercraft as claimed in claim 1, characterised in that said retention means comprise a seat (7) to house at least part of said sea scooter.

4. A watercraft as claimed in claim 3, characterised in that said seat (7) extends such as to house a large part of the sea scooter.

5. A watercraft as claimed in claim 3, characterised in that said seat (7) is provided in the stem (6) of said watercraft.

6. A watercraft as claimed in claim 3, characterised in that said seat (7) presents guide means (10) arranged to impose the same roll and/or the same pitch and/ore the same yaw on the sea scooter and on the watercraft.

7. A watercraft as claimed in claim 4, characterised in that said guide means (10) comprise a profile (12) arranged to at least partially house a perimetral projection (13) on said sea scooter.

8. A watercraft as claimed in claim 4, characterised in that said guide means comprise a profile (12a) shaped to correspond to the outer profile (8a) of the sea scooter.

9. A watercraft as claimed in claim 4, characterised in that said seat (7) comprises a support (14) for at least partially supporting the sea scooter.

10. A watercraft as claimed in claim 1, characterised in that said retention means comprise fixing means (20, 20a, 20b) to prevent said sea scooter from leaving said seat (7).

11. A watercraft as claimed in claim 10, characterised in that said fixing means comprise at least one tie rod (20) connected to said hull.

12. A watercraft as claimed in claim 10, characterised in that said fixing means comprise a pair of tie rods (20), each of which presents an end (21) connected to the hull (2) and an end (23) connected to the sea scooter.

13. A watercraft as claimed in claim 11, characterised in that said tie rods comprise means (25) for adjusting their tension.

14. A watercraft as claimed in claim 10, characterised in that said fixing means comprise at least one jaw (20a) arranged to at least partially obstruct access to said seat after the sea scooter has entered it.

15. A watercraft as claimed in claim 14, characterised in that said jaw (20a) presents means for locking said jaw in its closed position.

16. A watercraft as claimed in claim 10, characterised in that said fixing means comprise an inflatable element (20b) positioned between said hull (2) and said sea scooter (8), said inflatable element, when inflated, adhering to the profile of said sea scooter (8) and preventing its exit from said seat (7).

17. A watercraft as claimed in claim 16, characterised in that said inflatable element (20a) comprises, for regulating its internal pressure, a circuit connected to a pressurized fluid feed source.

18. A watercraft as claimed in claim 1, characterised in that said hull (2) comprises independent steering and/or propulsion means.

19. A watercraft as claimed in claim 1, characterised in that said hull (2) presents, associated with it, one or more fire-fighting pumps powered by electrical generators also provided on said hull.

20. A watercraft as claimed in claim 19, characterised in that said fire-fighting pumps present remote control means.

21. A watercraft as claimed in claim 1, characterised in that said hull presents tower-mounted lighting devices powered by electrical generators also provided on said hull.

22. A watercraft as claimed in claim 1, characterised in that said hull is equipped with a compressor to maintain self-ballasted lighting buoys under pressure.
