Marsaudon Composite
The ORC catamaran yard and the Paradox trimaran, based at the Lorient submarine base
Marsaudon Composites was founded in 1999 by Samuel Marsaudon and moved into the hangars of the former Keroman submarine base in Lorient, in the heart of the Bretagne Sailing Valley, in 2000. The yard specializes in vacuum-infused fast cruising multihulls, with a consistent design philosophy: minimizing displacement to achieve average speeds close to offshore racing.
Three successive owners in five years
In January 2018, Samuel Marsaudon sold the yard to Damien Cailliau and Frédéric Blandin. The company was then placed under collective insolvency proceedings, and in September 2023 the Lorient commercial court approved the bid fromGrand Large Yachting (Outremer, Allures, Garcia group), which acquired the assets, the ORC brand, and the 65 employees. Xavier Desmarest, CEO of GLY, announced the takeover at the Cannes Yachting Festival 2023.
The Ocean Rider Catamarans range (formerly TS)
In 2020, the yard renamed its TS range (Tres Simple) to Ocean Rider Catamarans. The current models are designed by Christophe Barreau, except for the ORC 57, which was entrusted to Marc Lombard Yacht Design.
- ORC 42(formerly TS42, launched 2014) — Christophe Barreau
- ORC 50(formerly TS5, launched 2017) — Christophe Barreau
- ORC 52.2— Christophe Barreau
- ORC 57(18.39 m × 9.61 m) — Marc Lombard Yacht Design; ORC 57 ADV version presented at the International Multihull Show in La Grande Motte in April 2026
Paradox, the 63-foot cruising-racing trimaran
Alongside the catamaran range, Marsaudon built theParadox trimaran (63 ft / 19.15 m) in 2010, designed by Nigel Irens and Benoît Cabaret from the moulds of Loïck Peyron’s Fujifilm (ORMA 60). Capable of 30 knots in racing, it has since completed three transatlantic crossings and sailed from Brittany to the Pacific.
