Rising Sun Everyone loves a good rivalry story. In the case of the 452-foot Rising Sun, launched in 2004, her story is about Oracle CEO Larry Ellison and Microsoft co-founder Paul Allen. These guys have been competing for years. When Allen ordered the 416-foot superyacht Octopus from the Lürsson yard in Germany, Ellison then placed an order for the 452-foot Rising Sun, which became the second-largest private yacht when he extended the hull from 387 feet during construction.
