JPK sailboats: a Breton racing yard built on Fastnet pedigree
JPK Composites builds its boats in Larmor-Plage, near Lorient, in what the yard calls the "French Sailing Valley," with a team of about 50 people. The brand's name is drawn from the initials of its founder, Jean-Pierre Kelbert, and the boats it has built since have carried that name to the biggest stage in short-handed ocean racing: in the 2013 Rolex Fastnet Race, Pascal and Alexis Loison won the race outright, across all classes, sailing a JPK 1010 named Night and Day — a result World Sailing called the first-ever doublehanded overall win in the race's history, and one the Royal Ocean Racing Club still credits as the only one.
Origins and ownership
Kelbert's path to boatbuilding ran through competitive windsurfing: he joined the French national team in 1986, became European champion in 1988 and 1989, and finished second in Olympic selection for Seoul 1988. In 1992 he founded JPK Composites to build top-of-the-range epoxy sandwich windsurfing funboards. The company's move into sailboats followed in the early 2000s, as the funboard market shifted toward Asia; contact with naval architect Jacques Valer accelerated that shift, and the first JPK 960 hit the water in March 2003. JPK Pacific handles the brand's distribution across the Asia/Pacific region.
The designers
Valer has been JPK's exclusive naval architect since 2003, a partnership the yard's own team has called central enough to nickname him "the magician." No Frills Sailing describes him as still the principal naval architect of every JPK yacht, known for hull designs under the International Rating Rules and, per JPK, one of the few architects capable of drawing everything from multihulls to one-design racers and fast cruisers. Jean-Baptiste "JB" Dejeanty joined as naval architect and development manager in 2020, supporting Valer's drawing and design work; Yachting World credits the pairing directly on the JPK 39 FC, listing the design as "Jacques Valer and Jean Baptiste Dejeanty / JPK."
Construction through the eras
JPK makes its own tools and composite parts in-house at Larmor-Plage, working across pre-preg, vacuum processing, wet lamination and infusion. Its hulls are vacuum infused over a foam-core sandwich, with stringers and longitudinal stiffeners laminated directly to the hull rather than bonded to an inner shell, and its keels are manufactured in the UK. Valer's design approach itself shifted with the JPK 1030 in 2019, which the yard describes as retooled specifically to win short-handed and single-handed offshore races — a scow-style, high-sail-area concept that the JPK 1050 took further in 2025.
Lines and generations
JPK's racing line runs from the 960 through the Valer-designed 1010 — whose Transquadra wins in 2006, 2009, 2012 and 2015 preceded its 2013 Fastnet triumph — into the 1030 and 1050, and includes the midsize 1080 and 1180. The 1080 was nominated European Boat of the Year 2015 after taking overall honors in both the Rolex Fastnet Race and the Sydney Hobart the same season, and later won its class at Sydney Hobart again in 2016 and 2017; the 1180, added in 2018, was again a Valer design, built with more volume in its forward sections. A separate Fast Cruiser (FC) line began with the 38 FC, which immediately won Sailboat of the Year 2013; the larger 45 FC followed for long-distance sailors, and the 39 FC replaced the 38 FC in 2021, winning both Sailboat of the Year and European Yacht of the Year in 2022. JPK is developing a 48 FC to succeed the 45 FC. Away from sailboats, JPK also launched a day sailor, the 998, and in 2023 introduced its first motorboat, the Nomad 40.
Who JPK is for
JPK's story is inseparable from short-handed ocean racing: Kelbert himself raced a new JPK 1030, also named "Léon," to a class win with Alexis Loison at the 2019 Rolex Fastnet Race, winning the IRC Double Handed division by five hours as JPK boats took podiums in four of that year's five divisions. That pedigree, paired with a Fast Cruiser line built for long-distance sailing, points the brand at owners who want a raceboat's build quality and results record, whether they're campaigning offshore or cruising further afield. It's also a smaller-batch builder by nature: in a 2018 profile, No Frills Sailing found JPK carrying waiting times of one to two years without attending boat shows or running advertising campaigns.
