Part of Constitution Dock with Mount Wellington (1270 m, 4000 ft.) in the background.
The dock was in process of being emptied of boats prior to arrival of the fleet
of 77 yachts in the Sydney-Hobart race starting on Boxing Day.
The yacht flying a US flag is the "Nine of Cups" registered in Denver, CO.
It's name derives from Tarot cards and represents notions of 'being contented', 'having dreams come true' etc.
An entertaining blog is available with many photographs showing the yacht's facilities,
recent travels around Tasmania, and elsewhere around Australia: http://www.sailblogs.com/member/nineofcups/
