World's first private icebreaker superyacht 'La Datcha', built for billionaire Russian banker Oleg Tinkov and costs over ₹6 crore/week to rent, was launched earlier this month by shipbuilder Damen. The 252-foot yacht comes with two helicopters, snowmobiles, and a submarine. It can reportedly travel through 16-inches of thick ice and can be used to explore the Arctic and Antarctic waters.
