USNS Guam (HST-1)

The USNS Guam (HST-1), formerly Hawaii Superferry's Huakai, is a United States Navy high-speed transport vessel. The ship was completed in September 2008 and was intended to start Hawaiian service in May 2009, though delivery postponements saw that planned service canceled. In the Hawaiian language, huakaʻi means "journey".
The design of the Spearhead-class Joint High Speed Vessel is 70 percent in common with the Hawaii Superferries, both built by Austal USA.

Vessel

Huakai was a 373-foot (114 m) long high-speed roll-on / roll-off (Ro/Ro) passenger and vehicle ferry operated by Hawaii Superferry. Huakai had a capacity of 866 passengers and up to 282 subcompact cars. It was 19 feet (5.8 m) longer than its sister ship, Alakai, due to a bi-fold ramp installed on the stern of the ship.

Just like Alakai, the vessel featured environmentally friendly technologies including non-toxic bottom paint, zero wastewater discharge and clean diesel engines.

Austal USA, a subsidiary of Austal, an Australian company that is the world's largest builder of fast ferries, built Huakai. Construction on Huakai began in 2007 in Mobile, Alabama. The ship was intended to enter service in 2009, but due to the abrupt shut down of the company the ship was laid up. Alakai also returned to the Alabama ship yard. On July 2, 2009 Hawaii Superferry decided to abandon the Huakai and Alakai.
