Career path: Lombard, Mauri, A2V, then Class 40
Guelfi studied naval engineering at the University of Genoa, where he met skipper Ambrogio Beccaria. He then trained at Marc Lombard Yacht Design in La Rochelle, then worked with naval architect Bert Mauri (notably on rudder profiles). With Fabio D'Angeli, he then spent seven years at A2V, a start-up developing ground-effect passenger catamarans. The duo returned to racing yachts by setting up in Lorient.
The Musa 40 and the Sangiorgio Marine partnership
The Musa 40 was designed by Guelfi and D'Angeli in collaboration with Beccaria and built by Sangiorgio Marine in Genoa (shipyard founded by Edoardo Bianchi in November 2021). The first example, Alla Grande-Pirelli, was launched in 2022 and immediately became the class benchmark: 2nd in the 2022 Route du Rhum, winner of the 2023 Transat Jacques Vabre, winner of The Transat CIC 2024 (Beccaria).
