Built by Feadship and completed in 2013, Winch Design is responsible for the iconic shapes that make up one of Holland’s largest yachts ever built. Her distinctive blue hull and extravagant light displays at night have made her one of the most recognisable yachts anywhere in the world. Her stretched foredeck is capable of stowing a private helicopter to take with her wherever she goes. Her elaborate interior, too, is the work of Winch Design.
