I saw that - an interesting concept that must have not caught on since they never built a second one. I don't know Joubert/Nivelt - good reputation?
Joubert/Nivelt ?
Probabely one off the more well know architect in France ( Unfortunately Joubert passed few year ago )
They design boat during around 50 year and also he navigate a lot and own different boat ( Tigre Mou a 47' steel schooner, a 20m light catamaran, Marguerite a 16 m alloy motor sailer, he made France/Tunisia/France in one day with his small motor boat "Lulu Belle")
Nivelt participate for design the US catamaran ( Stars and Stripes)who win the America cup.
On this site you have a couple who bought a 50' alloy catamaran Joubert/Nivelt.
They made design for boatyard like, Gib Sea, Beneteau, Dynamique Yacht, Océa ( trawler Esperitus Santus, long range Abilly Wheeler, Motor sailor Hortense...) Archambault, Racing catamaran like "Charente Maritime".Kiriè (ange de mer "trawler" in the seventies
We own a Chassiron GC ( Joubert adapt the drawing from wood to fiberglass), a Damien II (14 m steel schooner), he made the hull line of the 18 m motor sailor we built in Vietnam 33 year ago, he made the hull line of our Long-Cours 62 (19.45 m passagemaker), and the actual alloy Trawler 72'.
