A marine geophysical deflector for towing seismic arrays includes a float main body with one or more deflector wings extending downwards into the sea, and one or more slender top float elements arranged generally in a longitudinal direction on top of the main body. The number of the top float elements may be two or more. There may be arranged two or more distance floats below the float main body and an upper horizontal plate at the top of the one or more deflector wings.

1. A marine geophysical deflector for towing seismic arrays in the sea, comprising: a float main body with one or more deflector wings extending downwards into the sea;two or more elongated top float elements having a longitudinally extending boat shape with bow portion and aft portion;said one or more top float elements constituting an upper float element, placed on top of the float main body and arranged for letting said float run in a semisubmerged state so as for a waterline to be along said one or more top float element; andsaid one or more top float elements arranged aslant relative to a longitudinal direction of said main float, in the direction of said main float's intended course through the sea. 2. The marine geophysical deflector of claim 1, wherein the height of the top float element may vary between 3% and 16% of the total height of a deflector paravane. 3. The marine geophysical deflector of claim 1, wherein said top float element's bow portion has a rounded fore stern. 4. The marine geophysical deflector according to claim 3, wherein said fore stern has a negative rise angle. 5. The marine geophysical deflector according to claim 1, wherein said top float element's aft end of an aft portion has a pointed aft stern and wherein said aft portion is longer than the corresponding fore portion. 6. The marine geophysical deflector according to claim 1, wherein said top float element's aft end stern is straight. 7. The marine geophysical deflector according to claim 1, wherein each top float element is provided with a circular flange arranged for being connected to a corresponding top flange on said main float. 8. The marine geophysical deflector of claim 7, wherein bolt holes of said circular flange at the bottom of said top float and said top flange of said main body are arranged for being connected with a given deviation to either sides of a centerline of said main body, which allow for attachment of the top float turned either to starboard or port side relative to the longitudinal axis of said main body. 9. The marine geophysical deflector of claim 8, wherein said deviation angle is between 1 and 30 degrees. 10. The marine geophysical deflector of claim 8, wherein said deviation angle is between 12 and 18 degrees. 11. The marine geophysical deflector of claim 8, wherein said deviation angle is 15 degrees. 12. The marine geophysical deflector according to claim 1, comprising a two or more distance floats each arranged beneath said main float and for being connected directly or indirectly to said one or more deflector wings below. 13. The marine geophysical deflector according to claim 1, wherein said top float comprises a through vertical channel of width between one half and three quarters of the width of said top float, and provided with a bottom flange for connection to a top flange of a corresponding through vertical channel of said main body. 14. The marine geophysical deflector of claim 7, wherein said through vertical channel of said main body is provided with a bottom flange for connecting with a top flange of a through vertical channel of a distance float below. 15. The marine geophysical deflector of claim 14, wherein bolt holes of said circular flange at the top of said distance float and said bottom flange of said main body are arranged for being connected with a given deviation angle to either sides of a centerline of said main body, which allow for attachment of said distance float turned either to starboard or port side relative to the longitudinal axis of said main body. 16. The marine geophysical deflector of claim 8, wherein the deviation angles of said one or more top floats and distance floats are equal and to the same side. 17. The marine geophysical deflector of claim 12, wherein said distance float is provided with vertical bores for bolt connection to an upper horizontal plate of said deflector wings. 18. The marine geophysical deflector of claim 1, wherein the number of said deflector wings are between two and six, and that said deflector wings are connected by said upper horizontal plate at their top end, and connected by a lower horizontal plate at their bottom end, said upper horizontal plate and said lower horizontal plate connected with fore and aft upper and lower bridle lines joined at their opposite end at a bridle block to a towing line. 19. The marine geophysical deflector of claim 14, wherein the lower end of the vertical channel will end up and be closed at the upper horizontal plate of the deflector wing assembly. 20. A marine geophysical deflector for towing seismic arrays in the sea, comprising: a float main body with one or more deflector wings extending downwards into the sea wherein said main body comprises two or more straight sections and at least one nose section and a tail section;wherein the nose section includes an asymmetrical nose portion and a symmetrical rear interface for connecting to a straight section in ordinary or upside-down configuration; andwherein said nose section and said tail section are generally equal but attached with opposite orientations. 21. The marine geophysical deflector of claim 20, wherein the two or more straight sections include a forward section provided with a top flange for a forward top float, and a rear section provided with another flange for connecting to a rear top float. 22. The marine geophysical deflector of claim 20, wherein the two or more straight sections include a forward section provided with a bottom flange for connection of a forward distance float, and a rear section provided with another flange for connecting to a rear distance float. 23. The marine geophysical deflector of claim 20, wherein at least said nose section is provided with a shock absorbing material so as for reducing damage in case of flotsam impact. 24. The marine geophysical deflector of any of claim 20, wherein said straight sections are combined in one continuous material piece.
