Port Angeles, WA- Boatbuilder Brix Marine (formerly Armstrong Marine USA) has been contracted by aerospace and defense technology company, Northrop Grumman, to build a catamaran survey-research vessel, slated for fall 2021 completion.

The 44’ x 16’ vessel is Brix’s third IPS-drive catamaran; the first 2 were 4216-CTC models, both delivered in 2019, to UC San Diego’s Scripps Institution of Oceanography (R/V Bob and Betty Beyster) and Orca Maritime, Inc. (R/V Benthic Cat), respectively.

Northrop Grumman said they will utilize the vessel for testing commercial navigation systems, undersea and aviation programs, as well as assisting the Chesapeake Bay Foundation’s replenishment of local oyster populations and other community outreach and educational projects.

The 4416-CTC is powered by twin Volvo D11 510hp engines with Volvo IPS 650 propulsors and a dynamic positioning system (DPS) which automatically maintains heading and position and provides the precise control required for scientific operations. The vessel features a full-width cabin with flybridge, large aft working deck, open transom, 2 swim platforms, and a removable launch platform. Deck equipment includes a hydraulic A-frame (4200lb) with Pullmaster PL5 hydraulic winch, a Morgan Marine 200.3 crane, and 30 tie-down points for securing equipment.

Designed to accommodate overnights, the heated cabin includes a V berth in the forward cuddy, and a port side workstation with ample counter space and seating for 2. A head compartment with hot water shower is housed behind the workstation on the port side. The fold out table with flip down bench seats on the starboard side maximizes the cabin’s usable space.

Brix Marine designs and builds welded aluminum catamarans, monohulls, and Naiad RHIBs distinguished by quality craftsmanship and innovative design. Learn more at
