Claim One:
1. A method for steering a seismic vessel associated with a sail line and a current preplot line, said seismic vessel towing at least one acoustic linear antenna comprising receivers, said receivers receiving signals generated by at least one source and reflected by subsurface's layers at a plurality of reflexion points, comprising: a) computing distances d i , iε{1. .. n}, from n reflexion points, included in said plurality of reflexion points, to a boundary of an already obtained binning coverage zone associated with an already used previous preplot line; b) computing a distance D, from said n reflexion points to n target reflexion points, as a function of said distances d i ; and c) providing steering information comprising or based on the distance D to a navigation system or to an operator of a navigation system, to alter the course of the seismic vessel.
