A system and method that reduces spatial positioning control requirements for maintaining reduced wave-making resistance of at least one following vessel in a fleet operating in a seaway, by determining a position of the at least one following vessel within a coordinated zone, which is a zone within a reduced wave-making resistance region of the Kelvin wake of at least one lead vessel, at which a surge motion of the vessels is synchronized with each other. By positioning the at least one following vessel in the coordinated zone, the spatial positioning control requirements of the at least one following vessel can be reduced.
