Wally Introduces New Performance Racing Yacht wallyrocket71 at Loro Piana Giraglia 2025
Wally has officially presented its latest high-performance racing yacht, the wallyrocket71, during the 2025 Loro Piana Giraglia regatta. The 21.6-meter maxi yacht was developed through collaboration between Wally's technical team, designer Botin Partners, and owner Giovanni Lombardi Stronati, with construction completed by King Marine shipyard.The wallyrocket71 represents Wally's continued commitment to competitive sailing innovation, featuring advanced design elements including twin rudders, a high-performance bulb keel, and a sophisticated 2.7-ton water ballast system capable of transferring sides in approximately six seconds. With a displacement of 12 tons, the yacht is approximately three tons lighter than comparable Maxi 72 class vessels while maintaining similar sail area and power.Alberto Galassi, CEO of Ferretti Group, commented: "First and foremost, I want to express my thanks to the owner, Giovanni Lombardi Stronati, whose trust in this ambitious vision from day one made it all possible. With the wallyrocket71, Wally sets sail into an exciting new chapter in competitive yacht racing, launching a vessel designed to be one of the fastest in its class."Initial sea trials conducted in Valencia demonstrated the yacht's performance capabilities, achieving upwind speeds of 10.5-11 knots and matching wind speed downwind. Adolfo Carrau of Botin Partners explained the design approach: "We started from a blank sheet of paper, asking how we could beat the most competitive Maxi 72s on corrected time. When they were designed, it was to a box rule, so many parameters were already set. Now, as everyone is optimizing their boats under IRC rules, there is a lot more freedom."The racing crew, including tactician Vasco Vascotto and strategist Guillermo Parada, reported positive initial impressions of the yacht's handling and performance. Vascotto noted: "After only a few days on the water, I'm really impressed by both the construction quality and performance." Parada added: "The boat's performance is in line with our expectations: it is a complex and high-performing vessel that requires careful handling but is very exciting."The wallyrocket71 will compete in major Mediterranean events including the Maxi Yacht Rolex Cup in Porto Cervo and Les Voiles de Saint-Tropez, following its debut at the Loro Piana Giraglia.Wally's racing fleet continues to demonstrate strong performance in the 2025 season, with 15 yachts scheduled to compete across various events. Notable recent results include victories by Wally Cento V at the RORC Nelson's Cup in Antigua and dominant performances by Tilakkhana II at Palmavela. The wallyrocket51, Wally's smaller performance model, has also shown competitive results at the Central and Southern Tyrrhenian ORC National Championship.The remainder of the 2025 racing calendar includes prestigious events such as the Admiral's Cup in Cowes, the Rolex Fastnet Race, and the season-ending Rolex Middle Sea Race in Malta. Wally's growing fleet of performance yachts, ranging from the wallyrocket series to the larger Cento models, continues to establish the brand's position in competitive sailing circles.The wallyrocket71 project represents approximately 18 months of development from initial concept to launch, with the design team focused on creating a versatile yacht capable of strong performance across various wind conditions and course configurations. The yacht's construction at King Marine incorporated advanced composite materials and weight-saving techniques to achieve its target displacement.With the introduction of the wallyrocket71 and continued success of its racing fleet, Wally maintains its commitment to developing high-performance sailing yachts that combine cutting-edge technology with competitive results across international regatta circuits.Credits: Wally
