About No Stress
50m Hybrid superyacht NO STRESS delivered by Rossinavi in July 2023 is the first vessel delivered under the shipyard's BlueE initiative and offers a fantastic opportunity for anyone looking for a new turn-key hybrid superyacht under 500GT. It has been equipped with five different operating modes to maximise energy efficiency (whether at anchor or underway) and AI technology that monitors consumption when cruising in electric mode. It is a high-performance hybrid superyacht with dual fuel: diesel and battery allowing you to enjoy the electric experience on board to the fullest. A slender profile and sporty character with floor-to-ceiling windows designed by Enrico Gobbi - Team for Design matches her fast-displacement hull form and her overall design takes inspiration from the automotive world. NO STRESS offers accommodation for 10 guests in five staterooms, including Master suite on the main deck and two VIP suites, Double and Twin cabin on the lower deck. Her impressive range of 5,300nm at 10 knots with 10% reserve and top speed of 20.5 knots makes her an ideal option for a client looking for world cruising. On-deck highlights include a spacious, walk-around bow with a 10-square-metre pool and the aft cockpit overlooking a large open beach club.
