55-meter Feadship Explorer "Shinkai" Launched Feadship has launched another yacht and this time it is the 55-meter explorer superyacht "Shinkai". She was under construction as hull 708 and built for an experienced owner who will no doubt take her on long-range missions across the seas. Shinkai has been designed by Vitruvius Yachts in particularly Philippe Briand. As a result of the scope of use Shinkai is planned for, a number of special features have been built in to the yacht. As the planned adventures include taking on the North-West and North-East Passages, the former Project 708 was built with a steel hull strengthened to ice class. It also includes an advanced sonar system to explore the ocean floor. Below we see an image at launch taken by Dutch Yachting.
