The drift characteristics of the vehicle are presented for various combinations of wind and water currents. It is shown that extremely high drift rates are incurred for water currents normal to the vessel longitudinal axis. Curves are given for various combinations of wind and water currents and thrust configurations. Figures were computed for extended periods of time to show the damping characteristics of the vessel. Generally these curves show that the vessel equilibrium distance increases as the angle between the water current and vessel longitudinal axis increases and becomes unstable for water currents of 5.1 ft/sec at an angle of 90 degrees. It is shown that in all cases the equilibrium distance is less when the thrust is a function of vessel heading. (Author)
