About the Alliage

Alliage was founded in 1995; the company has since dissolved, however its designers continue to be well-known, active boatbuilders. The Alliage was designed by Jean Berret and Olivier Racoupeau; both men were avid regatta competitors. When French production boatbuilders called upon Berret he opened an office in 1978. Berret’s first work was for the Beneteau boayard; he designed the First 35 in 1979. Then in 1983 Racoupeau, trained in aeronautics and space science, joined Berret as his first employee. The pair designed many series boats for Beneteau, Alliage, Allures, Amel, Fountaine Pajot, and others, and partnered in 1994 to create Berret Racoupeu Yacht Designs. Berret and Racoupeau have designed roughly 15,000 custom yachts to date and their designs have won four world championships.

Detour has a cockpit with ample seating.  There is storage beneath the port side cockpit seat; also access to the interworkings of the engine exhaust, the steering system, and the autopilot.  Detour has a canvas dodger.  Lines run from the mast to the cockpit include:  main sail halyard, main sail sheet, main sail reefing lines #1 and #2, and centerboard lines.

The foredeck is easily maneuverable; hand railings line the topsides and the deck is covered in non-skid imitation teak.  All the way forward is a locker that houses the anchor chain, bow thruster, and electronic bilge pump.  The locker is large enough to store lines and sails.
