CMN was founded in 1946 by an aeronautical pioneer, Félix Amiot, who wanted to convert his plane factory to a shipbuilding. The Cherbourg site had enabled him to develop seaplanes. Félix Amiot gave CMN its first DNA oriented towards the search for speed and the search for lightness.
were delivered between the late 1960’s and the mid-80’s to Israel, Greece, Malaysia, Germany, Iran, Libya, Nigeria, Qatar and Tunisia.
At the same time, in the early 70’s, CMN developed for the French Navy a new generation of minehunters using underwater drones and equipped with low-speed diesel-electric propulsion.
The 60’s also saw the beginnings of CMN in the construction of pleasure boats with series of sailboats Maïca (11m) and super-Maïca (12m – 40′).
CMN built a few multihull ocean racing yachts including the trimaran Paul Ricard, equipped with foils, with which Eric Tabarly beat a 75 years record for crossing the Atlantic.
CMN built for the French Navy a series of 10 P400 patrol vessels (54m) which will be deployed in metropolitan France and Ultramarine. At that time, CMN developed a construction process in pre- impregnated carbon-epoxy by composite materials for the construction of the monohull sailboat Milène V (23m). In 1984, CMN acquired its first computer-assisted design stations (CATIA).
CMN built a 54m freezer trawler and delivered a series of 60m research vessels to Indonesia. In 1990, CMN built for the French DGA a catamaran prototype of 50 meters with surface effect the NES 200.
In 1992, under the impetus of a new shareholder, Iskandar Safa, the yard won several export contracts.
In 1995, CMN delivered three P400 patrol vessels to the Sultanate of Oman, with integrated logistic support and training for crews and maintenance teams.
CMN expands internationally with 2 companies:
CMN created a new range of BR Combattantes with deep-V hull and jet propulsion. The architecture of these boats is the result of a long research program on fast and stable hulls at high speed.
Eight 42m “BR 42 combattante” missile boats will be delivered to Kuwait between 1997 and 1999. To facilitate the integration of the weapon system for this project, CMN created a shore-based testing platform that was then used for crew training.
The Baynunah Corvettes Program (6 BR Combattantes of 71m) was built in cooperation with the United Arab Emirates Navy and the Abu Dhabi Shipyard (ADSB). This corvette has a weapons system that is normally found on larger ships (frigates) and can accommodatea 4-ton helicopter. CMN studied and built the prototype while organizing a technology transfer for the construction of the 5 next units at ADSB.
CMN developed a new type of ship: the DV15 interceptors. These 15m units are constructed of pre-impregnated carbon/epoxy composite materials and are equipped with surface propeller propulsion allowing them to exceed 50 knots.
CMN developed its civil activities with the construction of yachts (in the 30-60m range). The sailboat Mari-Cha IV (43m) will break the record crossing the Atlantic at the average of 19.5 knots. 2 motor-yachts of 60m, Slipstream and Cloud 9 will win 6 international prizes.
From 2012, CMN go into major research program to develop new products that best meet the new customer‘s request:
CMN has been working on marine renewable energy projects. CMN has built with Hydroquest a marine tidal turbine prototype (one megawatt power) which is being tested off in Paimpol since April 2019.
