System and method for calculating a pre-plot for a marine seismic acquisition system. The method includes receiving as input a first number of streamer vessels and a second number of source vessels; receiving a geometry of an area to be surveyed; receiving a set of naturally different regions and/or humanly set targets for the area to be surveyed; calculating a first sailing path for a streamer vessel of the first number of streamer vessels; calculating a second sailing path for a source vessel of the second number of source vessels, based on the set of naturally different regions and/or humanly set targets; and entering the pre-plot into a navigation system of the streamer vessel and the source vessel so that the streamer and source vessels dynamically change an offset distance between them, while sailing during a seismic survey, based on the naturally different regions and/or humanly set targets.
