Yet this design office, founded over 30 years ago in Valbonne in the south of France, plays an essential role in the construction of modern multihulls. As Hervé Tanneur, the company’s CEO, sums it up: “Since 1990, we’ve been the link between architects and shipyards. Our job is to optimize each part to reduce stress, manage weight, and facilitate construction. These are very concrete points, but they are what make the difference in the long run. And we also ensure that our choices are in line with cleaner boating.” Rivoyre Ingénierie’s expertise does not stop at new boats. In refit, the firm works on sensitive areas where safety and durability require precise diagnosis. Recalculating a mast, localized reinforcement, optimizing davits, fatigue analysis of a connecting arm, repairing a stressed structure: these are often overlooked operations, but they are crucial for the (long and peaceful) life of a multihull. Rivoyre Ingénierie is involved in an impressive number of multihull programs. Projects range from 50-foot cruising boats to super-catamarans over 110 feet long, including semi-custom and entirely one-off models.
