This paper presents the main results of an investigation regarding the effectiveness of reducing the wave resistance of a system of sea vehicles by varying the lateral and longitudinal offsets of each ship. A high-order free-surface Rankine-source boundary element method was used to conduct simulations on a series of seven adapted medium-sized autonomous surface vehicles operating at 3 different lateral offsets and 5 different longitudinal offsets with Froude number 0.4. An analysis of wave resistance, wave pattern, and wave spectrum is conducted to understand the effect of wave pattern interference. Several configurations show promise in reducing the total wave making resistance.
