70m Rossinavini Superyacht High Power III Seen on First Sea Trial After Major Refit

The 70m superyacht High Power III, originally known as Numptia, has returned to the water for her first sea trial following a major refit at the Fassmer shipyard in Germany.

Built in 2011 by Rossinavi, the vessel was seen entering the shipyard in September of last year. The full scope of work carried out at Fassmer has not been disclosed.

​High Power III's interior, designed by Salvagni Architetti, offers a blend of elegance and comfort. The main deck features a central saloon with a cathedral-style teak ceiling, rounded curves, and sea urchin-inspired lights. A bar extends along one wall, complemented by floor-to-ceiling windows that provide panoramic views. The dining area includes an alpaca table seating 12, accessed through sculpted alpaca doors.

Outdoor features of the yacht include a sundeck with an infinity pool that can transform into a bubbling spa pool, a helipad convertible into a dance floor, and an aft deck with custom-designed double sun beds.

Constructed with a steel hull and aluminium superstructure, the motor yacht was built for stability and long-distance cruising. Her exterior was drawn by Studio Spadolini, while Salvagni Architetti handled the interiors. The layout accommodates 12 guests across six cabins, including a full-beam master suite on the main deck and a VIP suite on the bridge deck. Four additional guest cabins sit on the lower deck. She runs with a crew of 18.

High Power III has collected awards in the past, including the Judges' Special Award at the World Superyacht Awards and the Naval Architecture Award at the ShowBoats Design Awards in 2012. These accolades point to her strong original build and design pedigree.

With the sea trial now complete, High Power III is expected to resume cruising soon, either privately or on the charter market.
