On February 14, the world's largest high-speed ferry catamaran Stena Discovery took off from Belfast, after a planned drydocking, and about one hour out at sea on the captain's command the waterjet control was switched over to steering by a retrofitted Humphree Interceptor Steering System. While the interceptors engaged and provided the means for directional control of the vessel, the steering buckets of the four Kamewa 160 SII waterjets, in total absorbing a power of 68.5 MW, automatically returned to their neutral, or boost position, allowing all waterjet thrust to be vectored forward for maximum thrust, and eliminating the waterjet bucket drag.
