135222The financial crisis isn't just spoiling Dasha Zhukova's dreams of a lavish wedding. The girlfriend of billionaire Russian oligarch Roman Abramovich now has to contend with the fact that she may not be able to sunbathe aboard the world's largest yacht next summer. Abramovich is thinking about backing out of a deal to buy a $355 million boat named the Eclipse, which, if it's ever finished, would be the largest yacht ever constructed. (Abramovich had planned to equip the 530-foot vessel with three helipads and its own submarine.) One possible contingency plan? Drop Roman and get together with Ron Perelman. He's still going ahead with plans to build a giant, new boat and it will be finished this spring, just in time for the summer season. [Luxist]
