Heesen motoryacht Alive
Heesen Yachts says the 139-foot Alive has just completed sea trials and exceeded her contractual speed by a half-knot, achieving a top speed of 16.4 knots in calm seas with 3- to 4-knot winds.
As expected, Alive displayed a range of 4,000 nautical miles at 12 knots based on fuel consumption during the trials. According to Heesen, the design uses 30 percent less fuel than a conventional displacement yacht because of an underwater foil called Hull Vane that harnesses waves to produce power.
The Hull Vane design was completed with independent research by Van Oossanen Naval Architects at the hydrodynamic labs Wolfson Unit and Marin.
Alive was delivered to her owners November 4. Her exterior styling and interior design are by Omega Architects. She has a steel hull with aluminum superstructure, and she accommodates 12 guests.
