Harmony sailboats: a Poncin Yachts brand shares its name with two unrelated boats
"Harmony" on a used-sailboat listing does not point to one company. Most often it names a French monohull cruising brand that Olivier Poncin launched in 2001 under his company Poncin Yachts — the same firm that, after buying the bankrupt Catana catamaran yard in 2003, renamed itself Catana Group in the 2013/2014 fiscal year. Two other boats carry the name by coincidence rather than lineage: the Harmony 22, a compact 1977 American one-design built by an unrelated company also called Harmony Yachts, and the Harmony 31, an older design that predates the French brand by decades. Matching a listing to its actual history starts with telling these three apart.
Origins and ownership
Olivier Poncin's yachting career began in 1983, when he took over the Kirié shipyard in Les Sables-d'Olonne with a group of friends. He bought Dufour in 1988, and by the time he sold the shipyard in 2001, Dufour had produced more than 150 multihulls under his ownership; along the way, he was also among the founders of the Nautitech catamaran brand. After leaving Dufour amid corporate differences, Poncin set himself a new challenge: founding Poncin Yachts and launching Harmony, a monohull cruising brand, in 2001. He spent 2003 to 2010 based in La Rochelle immersed in the Harmony project, but the 2008 financial crisis halted it, leaving behind a state-of-the-art factory in Marans, on France's Atlantic coast north of La Rochelle. Poncin Yachts had by then already expanded in a different direction: sensing rising demand for catamarans, Poncin bought the bankrupt Catana shipyard in 2003, taking on its staff, buildings, stock, and assets six years after Catana had relocated to Canet-en-Roussillon. That side of the business outlasted Harmony — Catana Group's own investor archive lists a filing titled "Poncin Yacht devient Catana Group," dating the corporate rename to the 2013/2014 fiscal year, and in September 2014 the renamed group launched its first Bali catamaran, the Bali 4.5. Poncin led the company until his death at 69, in Perpignan; a Giornale della Vela obituary said his son then took over what it called one of the most important players in the market.
The designers
Design credit for the French Harmony range belongs to Mortain & Mavrikios, though the partnership itself predates Harmony by nearly a decade. Poncin's collaboration with the firm began on Nautitech catamarans, starting with the 475 in 1994 and followed by the 435 and 395, years before the Harmony monohull line existed. Mortain & Mavrikios, a French naval architecture bureau, is credited as the designer of the 47, the 38, and the 34, the range's entry-level model added in 2006. The unrelated American Harmony 22 came from a different hand entirely: Chris Bjerregaard, who drew it as a Midget Ocean Racing Club racer for the small yard that built the boat starting in 1977.
Construction through the eras
French-built Harmony hulls used vacuum-infused sandwich construction in fiberglass-reinforced polyester, with a PVC foam core and Kevlar reinforcement layered into high-stress zones such as the keel area. On the 47, ribs were pre-positioned during layup and became integral with the hull during resin injection, producing an extremely stiff structure; the 34 used a comparable open-mould process with its own Kevlar reinforcement in high-load areas. The 38 was built to a price, with interior joinery and hardware simpler than the premium cruisers it competed against, paired with a light-displacement hull and bulb fin keel.
Lines and generations
The French range grew to five models — the 34, 38, 42, 47, and 52-5 — with the 47 anchoring the range's midpoint. The 34 arrived in 2006 as the entry-level model and was the last significant addition before the 2008 financial crisis forced a halt to Harmony monohull production; the 47 was built over roughly the same 2004-to-2008 stretch. Two unrelated boats also carry the Harmony name. The Harmony 22 is a compact American one-design from 1977, built by a different company entirely, with only 37 hulls produced. The Harmony 31, built between 1964 and 1968, predates the French brand by decades.
Who Harmony is for
For a buyer, "Harmony" functions less as a single brand promise than as three separate answers, depending on which boat is actually in front of them. The French range suits someone drawn to a mid-2000s performance cruiser from a small, design-led yard with a documented lineage running back through Nautitech to Poncin's Dufour years. The American Harmony 22 suits a buyer after a light, trailerable one-design racer from a scarce production run. A Harmony 31, built between 1964 and 1968, predates the others by decades.
