The invention involves a double trim tab for watercraft in which connection the flow interceptor (1) is activated by an actuation cylinder (4) and the flow interceptor (1) activates the bottom tab (2). One of the tabs may have a course correction device (10) or a course correction fin (11). In addition, an electronic steering device (14) can likewise carry out a course correction in the event of a trim change in which connection the steering wheel (17) is kept neutral by means of an uncoupling device (18).

1. A double trim tab (A) for watercraft, comprising: a bottom tab (2), said bottom tab configured for mounting to a watercraft;a flow interceptor (1) pivotally mounted at an upper side of the bottom tab to pivot toward and away from the bottom tab about a first laterally-extending axis, said flow interceptor including a flow interceptor end (1a) extending toward the bottom tab to overlap one of a forward edge and a rear edge of the bottom tab extending generally laterally between outer longitudinal sides of the bottom tab; andan actuator (4) connected to the flow interceptor and configured for mounting to the watercraft for upwardly and downwardly pivoting the flow interceptor between a raised position with the flow interceptor end above a bottom surface of the bottom tab, and a lowered position with the flow interceptor end extending below the bottom surface of the bottom tab. 2. A double trim tab as claimed in claim 1, wherein the bottom tab (2) is configured for pivotal movement about a second laterally-extending axis at the watercraft, with a return spring (6) for upward movement and a limit stop (6a) for limiting upward movement. 3. A double trim tab as claimed in claim 2, wherein the bottom tab (2) is pivotal downward about the second axis from a position at the limit stop (6a), by pivoting the flow interceptor (1) downward beyond an intermediate position where the flow interceptor contacts the bottom tab. 4. A double trim tab as claimed in claim 2, wherein the bottom tab (2) includes hinges (3a, 3b) for defining the second laterally-extending axis. 5. A double trim tab as claimed in claim 2, further comprising a flexible connecting element (7) connected between the bottom tab (2) and the flow interceptor (1). 6. A double trim tab as claimed in claim 1, wherein the flow interceptor (1) includes a course correction device (10). 7. A double trim tab as claimed in claim 6, wherein the course correction device (10) is formed by the flow interceptor end (1a) being closer to the first axis at one side of the flow interceptor (1) and more distant from the first axis at the other side of the flow interceptor. 8. A double trim tab as claimed in claim 1, wherein the actuator includes an electric drive. 9. A double trim tab as claimed in claim 1, wherein the actuator includes a fluid cylinder. 10. A double trim tab as claimed in claim 1, wherein the fluid cylinder includes a lift locking device. 11. A watercraft having a double trim tab (A), said double trim tab comprising: a bottom tab (2) mounted to said watercraft;a flow interceptor (1) mounted at an upper side of the bottom tab to pivot toward and away from the bottom tab about a first laterally-extending axis, said flow interceptor including a flow interceptor end (1a) extending toward the bottom tab to overlap one of a forward edge and a rear edge of the bottom tab extending generally laterally between outer longitudinal sides of the bottom tab; andan actuator (4) connected between the flow interceptor and the watercraft for upwardly and downwardly pivoting the flow interceptor between a raised position with the flow interceptor end above a bottom surface of the bottom tab, and a lowered position with the flow interceptor end extending below the bottom surface of the bottom tab. 12. A watercraft as claimed in claim 11, wherein the bottom tab is fixedly mounted at a stern of the watercraft. 13. A watercraft as claimed in claim 11, wherein the bottom tab is hingedly mounted at a stern of the watercraft for pivotal motion about a second laterally-extending axis. 14. A watercraft as claimed in claim 13, wherein the bottom tab is pivotal downward about the second axis, by pivoting the flow interceptor (1) downward beyond an intermediate position where the flow interceptor contacts the bottom tab. 15. A watercraft as claimed in claim 14, further comprising a switch (12) that is configured to operate the steering device (14) when the actuator (4) is operated. 16. A watercraft as claimed in claim 11, wherein the flow interceptor (1) includes a course correction device (10) and the watercraft includes a steering device (14) configured to assist the course correction device during actuation of the double trim tab (A).
