Promise. – the full stop in the name is intentional – was the first Feadship built to ice-class notation. The exterior of this truly unique 51.00-metre custom explorer comes from the boards of Feadship’s in-house designers at Studio De Voogt with the interior created together with Bannenberg & Rowell Design. Twin Caterpillar C32 engines give a top speed of 14.5 knots while the yacht has a range of 4,500 nautical miles and luxury accommodations for twelve people.
