Vigor delivers third Hydrus-class ferry for San Francisco


The following is text of a news release from Vigor:

(SEATTLE) — Vigor recently delivered Argo, the third of four all-aluminum, 400-passenger ferries to the Water Emergency Transportation Authority (WETA) in San Francisco, Calif. The hull was constructed at Vigor Ballard and the superstructure in Vigor’s new aluminum fabrication bay at its Harbor Island facility.

“The new fabrication bay significantly expands Vigor’s production capabilities and capacity for our portfolio of aluminum workboats, high-performance military craft and state-of-the-art ferries like Argo,” said Tim Kolb, Vigor Puget Sound general manager. “It was fitting to have this award-winning design be our inaugural vessel for the new facility.”

Like its sister ships, Hydrus and Cetus, Argo is an efficient, environmentally friendly design by Incat Crowther. The ferry has a service speed of 27 knots and a smooth, quiet ride which Vigor senior project manager Jim Gow attributes to its “floating house.” The superstructure has 180 independent mounts. The engines and wheelhouse sit on isolation mounts while the gears are hard mounted.

“This configuration greatly reduces vibration, increasing passenger comfort,” said Gow.  

Argo features a selective catalytic reduction (SCR) aftertreatment system developed by Pacific Power Group and is powered by two MTU 12V4000 M64 engines. Argo’s engines are able to burn biodiesel B5 and thereby further reduce emission, a high priority for the city of San Francisco. 

Construction of Carina, the fourth WETA ferry in the Hydrus class, is already underway at Vigor with delivery expected by the end of 2018.
