The device comprises a plurality of deflector members (1) having a submerged lower face (2), called first face, generally fitting into the extension of the hull bottom (FC) of the ship, toward the rear thereof, while forming an angle (α) in relation to a general plane (Δ) tangent to this bottom (FC)

The device comprises a plurality of deflector members (1) having a submerged lower face (2), called first face, generally fitting into the extension of the hull bottom (FC) of the ship, toward the rear thereof, while forming an angle (α) in relation to a general plane (Δ) tangent to this bottom (FC), characterized by the fact that these deflector members (1) are articulated to the hull and are juxtaposed side by side, over all, or practically all, the width of the stern, control means (4) making it possible to cause it to pivot in one direction or the other in order to vary said angle (α), these means being housed in part in a protective case.

1. A ship, with a displacement speed between 10 and 25 knots or a cruising speed between 18 and 45 km/h and a Foude number which does not exceed 0.28, a stern of which is equipped with a device for deflecting flows of water, comprising several deflector members (1) having a submerged lower face (2), called first face, fitting overall into an extension of the hull bottom (FC), toward the rear thereof, while forming an angle (α) in relation to a general plane (Δ) tangent to this bottom (FC), each of these deflector members (1) being articulated to the hull, control means making it possible to cause it to pivot in one direction or the other in order to cause said angle (α) to vary, characterized by the fact that, on one hand, these deflector members (1) are similar and juxtaposed such that they extend transversely side by side, over all, or nearly all, the width of the stern, each of them consisting of a case with a rear face or second face (3), also at least partially submerged, able to be lowered by increasing said angle (α), so as to form an approximately vertical wall opposing slamming by rear surge, and that, on the other hand, said means for controlling the pivoting of each deflector member (1) comprise at least one hydraulic jack (4), the body (42) of which is housed in a protective case (43) integral with the structure of the hull and the rod (41) of which is inserted between the rear portion of the hull and the case (1) for which it controls the pivoting, such that this jack is sheltered from the surge and waves. 2. The ship according to claim 1, characterized by the fact that each case (1) is closed on top by walls (6, 7) turned upward and frontward, respectively, forming a dihedron, and is closed on its sides by lateral vertical walls, said hydraulic jack being inserted between the stern structure of the ship and an angular zone of this dihedron, such that it is isolated in a relatively enclosed space in the upper portion of the dihedron. 3. The ship according to claim 1, characterized by the fact that said control means make it possible to vary said angle (α) in a range between a negative value, corresponding to an orientation of said first face (2) inclined upward and rearward in relation to said general plane (Δ), and a positive value, corresponding to an orientation of this first face (2) inclined downward and rearward in relation to this general plane (Δ). 4. The ship according to claim 2, characterized by the fact that said control means make it possible to vary said angle (α) in a range between a negative value, corresponding to an orientation of said first face (2) inclined upward and rearward in relation to said general plane (Δ), and a positive value, corresponding to an orientation of this first face (2) inclined downward and rearward in relation to this general plane (Δ). 5. The ship according to one of the preceding claims, characterized by the fact that said control means comprise a set of hydraulic jacks (4) working synchronously. 6. The ship according to claim 5, characterized by the fact that said hydraulic jacks (4) are voluntarily controlled by actuating a maneuvering member. 7. The ship according to claim 5, characterized by the fact that said hydraulic jacks (4) are controlled by a shuttle valve, subjugated to the speed and/or trim of the ship. 8. The ship according to claim 1, characterized by the fact that said first face (2) is substantially flat. 9. The ship according to claim 1, characterized by the fact that said first face (2) is made up of two substantially flat front (2a) and rear (2b) facets which form an obtuse angle dihedron open downwardly. 10. The ship according to claim 1, characterized by the fact that said second face (3) is substantially flat. 11. The ship according to claim 1, characterized by the fact that said second face (3) is made up of two substantially flat upper (3a) and lower (3b) facets which form an obtuse angle dihedron open toward the rear. 12. The ship according to claim 1, characterized by the fact that the set of deflector members (1) has a shared pivot axis (W1-W2). 13. The ship according to claim 1 or claim 12, characterized by the fact that the pivoting of all of the deflector members (1) is done jointly, over a same angle (α), using said pivot control means. 14. The ship according to claim 1 or claim 12, characterized by the fact that the pivoting of the different deflector members (1) is done in a differentiated manner, with different angle (α) values, using said pivot control means. 15. The ship according to claim 1, characterized by the fact that its stern is provided with a spoiler (BE) serving as a shield (9) able to protect the deflector member (1) as well as the hydraulic jacks (4) from the assault of the surge and waves coming from the rear. 16.
