Forward thinking comes to life

Winch Design is delighted to be working with Heesen to design the exterior and interior of this 66-metres steel yacht. The sculptural surfaces of the concept reflect the sky and ocean, creating a muscular contemporary appearance. By incorporating a raised pilothouse, a sporty profile is achieved as well as an Owner’s stateroom with panoramic views, overlooking the relaxation area on the foredeck. Dynamic architecture emphasises the elegant sheer line which connects the strong bow to an inviting transom. The stepped aft deck area harmonises interior and exterior living, creating easy access to the infinity edge pool and surrounding waters.

First impressions

The fresh, contemporary interior features a full beam main deck, filled with plenty of light thanks to the panoramic windows. The infinity pool measures 5 metres and a large tender garage under the fore deck accommodates a limousine tender and rescue boat. Various customisable suite options are available to suit different desires, and the lower deck offers a full spa option, with gym, Hamman and sauna. The Owner’s stateroom connects to a private sky lounge aft, opening up to an exterior dining table. Guests can enjoy a private relaxation area fit with Jacuzzi and bar on the yacht’s spacious sun deck, which is connected to the other 3 decks via a glass elevator. With lounges on 2 levels, and both exterior and interior dining for up to 12 guests, family living and relaxation are at the heart of this Winch Design concept.
