Image 4 of 5 from The World's biggest megayacht still on the drawing boards - for now

February 7, 2005 In recent weeks we've written about several of the world's largest megayachts: the 118 metre Phillipe Starck-designed Sigma, Microsoft co-founder Paul Allen's Octopus and the 138 metre Rising Sun owned by Oracle Software founder Larry Ellison. Now there's a new megayacht on the drawing boards that will be bigger than all of them if it gets built - a 147 metre palace on water which sets new standards for design and functionality including its own cinema, disco, swimming pool, helicopter, integrated tender vessel and, would you believe, an integrated submarine.
