RV Western Flyer is a twin hulled SWATH research vessel operated by the Monterey Bay Aquarium Research Institute (MBARI). Its relatively stable SWATH design permits expanded operational capability in rough sea states. It is the platform of operations for the ROV Doc Ricketts (named after Ed Ricketts). The vessel carries 10 crew, 5 ROV pilots, and 11 scientists, for a total complement of 26. Cruises generally center around the central California coast and Monterey Bay, although excursions further afield to Hawaii, the Pacific Northwest, and the Gulf of California have taken place in recent years.
Accommodations are provided for a combination of 26 crew members and scientists in 14 staterooms located on the upper deck. The crew complement is ten for all voyages and the combination of ROV staff and scientists (16) brings the total vessel complement to 26.
The main machinery plant is diesel electric with a common power bus connecting five generators. Any combination of generator operation will provide power for both propulsion and other vessel operations. This design arrangement provides a high level of machinery plant redundancy and operational flexibility. Propulsion power is transmitted through two duplicate drive trains, each consisting of a DC electric motor and fixed pitch propeller. Silicon controlled rectifiers (SCR's) are used to convert generated AC power to DC propulsive power. Two electric motor-driven bow thrusters are installed to enhance maneuvering and station-keeping.
