The present invention provides a steerable hydrofoil. The apparatus includes at least one steerable hydrofoil panel 415 (1-2), at least one body part 417 (1-2) coupled to the at least one steerable hydrofoil panel to allow the at least one steerable hydrofoil panel to rotate about an axis 420, and at least one actuator (430, Fig 4B) for rotating the at least one steerable hydrofoil panel by a selected angle about the axis. Other embodiments of the invention disclose the use of the steerable hydrofoil panel on a marine seismic streamer 425. The steerable hydrofoil panel may be mounted on a marine seismic streamer behind a separate hydrofoil (330, Fig 3) and may be used to steer the streamer out of the wake (345, Fig 3) caused by said separate hydrofoil. |
