The yard revealed that the buyers of the in-build superyacht are American couple Bob and Amy Book, who had previously owned a 47-metre Heesen motor yacht named Book Ends (now Artisans) which they sold in 2017. Thom Conboy from Heesen USA helped close the brokerage deal in just under two months.
Under construction at Heesen’s Oss-based shipyard, Project Sapphire is also known as YN 19850 and is the second hull in Heesen’s new semi-displacement 5000 aluminium class.
Key features include a low-drag hull, reduced transom depth and draught of just 2.15 metres. Exterior design comes courtesy of Frank Laupman’s Omega Architects while Van Oossanen Naval Architects is behind the naval architecture.
The “refined and elegant” interior meanwhile has been penned by Cristiano Gatto in an “18th century modern” style. Accommodation will be for a total of 12 guests in four lower deck cabins and a master stateroom on the main deck. There is also accommodation for nine members of crew on board.
Project Sapphire is set to feature a multitude of outdoor seating and dining areas, as well as a large bar, whirlpool and spacious sun deck. A full-height tender garage doubling as a luxury beach club will sit beneath the aft sunbathing platform.
Twin MTU 16V4000M65L ‘green oceanic’ engines specifically designed to reduce NOx emissions will provide a top speed of 23 knots and range of 3,100 nautical miles at 11 knots.
After visiting the shipyard in August, Project Sapphire’s owner Bob Book said: “The technology is amazing; think of it as a 50m semi-displacement hull design with a seven-foot draft and a top speed of 23 knots.
“This boat is perfect for both the Bahamas and the Med. Needless to say, she is beautiful, sexy, spacious, stable and fast."
Delivery of the superyacht is scheduled for summer 2022.
