air-sea rescue vessel now in ser- vice. The vessel will be powered by a pair of 250-hp Cummins diesels driving 34-in. propellers through Twin Disc 3:1 reduction and reversing gears. It will be named after Robert G. Brownlee, a philan- thropist. Nichols Brothers Boat Builders recently refurbished Cat Express, installing new interiors and a ride control system especial- ly designed for the vessel by Maritime Dynamics, Inc. (MDI). MDI's ride control system for Cat Express consists of a hydraulically operated trim tab on each hull. These are automatically posi- tioned by an electronic controller to maintain optimum platform trim and to reduce accelerations arising from pitch, roll and heave motions that cause passenger dis- comfort and motion sickness. MDI worked closely with the ves- sel's designer, International Catamarans (Incat), and Nichols Brothers to design this system for the vessel, taking into account pre- vailing sea conditions of its route. MDI provided the detailed design and hull integration of the trim tabs, the hydraulic specifications and the electronic controller. Nichols Brothers fabricated trim tabs and designed and procured the hydraulic parts. Elliott Bay Design Group (EBDG) has designed a specialized seismic research catamaran (pic- tured on page 26) that disassem- bles for shipment to remote sites. Based on a preliminary design by Coastwise Engineering, the catamaran is now under construc- tion at Peregrine Marine in Anchorage, Alaska. "While the vessel itself is not highly unusual, its ability to be taken apart and trucked or barged to a new site is," said EBDG's Jim Cole, project manager. The catamaran — due for com- pletion in July — will carry seismic equipment on a cargo deck, span- ning the space between the two hulls. The aluminum catamaran will be 78 ft. (23.7 m) long, with a 34.5-ft. (10.5-m) beam and a three-ft. draft. It will be powered by four 800-hp Lugger diesels, driving Traktor model jets.
