In all probability the yacht with the blue hull in the Bay is Atessa. She is 225 in length and probably has a helipad with aircraft on the stern. Owned by Montana multi-billionaire Dennis Washington (mining and construction). We saw her last summer at the Wharf in Victoria, BC where crew confirmed that she was the one in Bandaras Bay for 3-4 months last season.
I notice it is gone today. Maybe out for a spin. Rumor has it that she has been eclipsed by Washington's newer, bigger yacht, Atessa IV, which is some 350 feet long. Check it out on a Google search.
