Besides being a truly innovative design that set a new standard at the time, the ARPEGE is also one of Dufours most successful models, financially and on the race course.
For the US market, the ARPEGE was sold in 2 versions, one at 30 feet and one at just under 30 feet, the latter to accommodate the MORC rule. Some boats had a deeper keel than the one shown here.
More than 1500 were sold world wide.
