Here's some news on USN high-speed catamaraon HSV2
Swift operating in the Pacific:
US Navy catamaran comes to port
30 Nov 2006
KUCHING: The US Navy high- speed catamaran, HSV2 Swift, will be making its first port call here today.
The 98-metre catamaran was delivered to the US Navy on Aug 15, 2003, and had operated as a mine warfare command-and-support ship, Marine Corps troops experimentation platform and high- speed lift for relief operations.
The Swift, which was assigned to the US Seventh Fleet, Pacific Command, had contributed to humanitarian efforts in the global community.
The vessel transported relief supplies to Aceh, Indonesia, following the December 2005 tsunami, New Orleans after Hurricane Katrina and Lebanon this year.
With its 70-tonne ramp, high speed manoeuvrability and precision navigation equipment, it could load, transport and unload up to 500 tonnes of equipment and cargo in remote or shallow draft ports without the use of tugs or cranes.
It had a crew of 45 officers and enlisted men, complemented by another 20 officers and enlisted men of the Navy Air Department. It also carried a platoon of 30 US marines.
The vessel carried a SH-60B Seahawk helicopter, the sea variant of the famous UH-60 Blackhawk, and three Rigid Hull Inflatable Boats or RHIBs.
Under the command of Commander Charles Rock, the Swift had circumnavigated the world three times and visited every continent, but Antarctica.
================================
If the catamaran had circumnavigated the world 3 times already, I'd say it's a stable enough platform to operate in the Pacific...
