With interior and exterior lines by Studio Vafiadis, she can accommodate 12 guests on board in 11 staterooms. As the largest superyacht built by Golden Yachts to date, she is the flagship of the Greek shipyard's fleet. Standout features on board include her large beach club, complete with wellness and spa centre and her touch-and-go helipad located on the bow for helicopters up to a size MD500E. The steel-hulled displacement motor yacht is powered by twin Caterpillar 3516C diesel engines that give her a maximum speed of 17 knots and a cruising speed of 14 knots.
