Abstract : The 1993 U. S.Coast Guard Boat Series study was initiated to define a set of seakeeping criteria to distinguish the seakeeping merits of a range of boats, each with the same mission profile and operational areas. The merits of the seakeeping performance were measured by the speed weighted percent time of operation (WPTO). It was determined that neither pitch nor heave motion components can be affected by boat design for a given size, because the boats spend a very large part of their operating time in the wave contouring' mode. The best distinguishing criteria among the different boats was roll motion and crew performance limiting criteria of Motion Induced Interruptions and Motion Sickness Incidence. These crew performance limiting criteria were strongly affected by roll motions.
