A method of controlling position of a seismic streamer (12) comprises: calculating magnitude and direction of a desired total force or displacement to apply to the seismic streamer; adjusting, based on forces exerted on the streamer by hydrodynamic deflecting surfaces (28) in a force axis, the calculated magnitude of total force or displacement to form an intermediate desired total force; adjusting a common angle between hydrodynamic deflecting surfaces (28) to produce the intermediate desired total force along the force axis; comparing the calculated desired common wing angle to the current common wing angle to calculate a change in the wing angle; and introducing a splay angle in to the hydrodynamic deflecting surfaces to produce a rotational movement to align the force axis with the direction of the desired total force.
