CMN uses the highly sophisticated computer assisted CIRCE-CATIA-RIMBAUD for modern design and shipbuilding technology.  This design and manufacturing system is directly linked to the cutting machinery operations, and enables 2D and 3D plans realisation (hulls form, hydrostatics and stability calculation, piping and electrical plans). This modern technology enables CMN to build every year up to 10 vessels of all types (military,  harbour craft, fishing boats…) in steel, aluminium, advanced composite materials and wood.
