No introduction needed for Jean-Pierre Kelbert<\/a>, who gave his initials to the\u00a0JPK<\/a>\u00a0yard, whose various models have\u00a0won everything in IRC<\/strong>\u00a0over the past twenty years, both in France and internationally. A busy SME owner with more than 50 employees, the 62-year-old builder still has an undiminished appetite for competition and is lining up solo once again in the third edition of the\u00a0Cap Martinique<\/a>, which starts on Sunday from La Trinit\u00e9-sur-Mer bound for Fort-de-France, with a strong fleet of\u00a032 double-handed crews and 14 solo sailors<\/a>. A race that also shapes up as\u00a0a battle between boatyards<\/strong>.<\/em><\/p>\n

With so many JPKs (18) on the start line of the Cap Martinique, do you even need to promote the yard anymore? Are you racing just for fun?<\/strong>
\nExactly, I\u2019m going with no pressure. In fact, I hadn\u2019t planned to do the race again and\u00a0it was the boat\u00a0(the JPK 10.50)<\/em>\u00a0that made me want to come back<\/strong>. It\u2019s probably my last one and I thought it would be a bit silly to miss out. So I arranged things with a client who lent me her boat, the one we won the Spi Ouest-France with. There will be\u00a0three 10.50s<\/strong>, with\u00a0Alex Ozon<\/strong>, who won in 2022\u00a0[on a Sun Fast 3300, ahead of Jean-Pierre Kelbert, editor\u2019s note]<\/em>\u00a0and will skipper\u00a0L\u00e9on<\/em>, the yard\u2019s boat, and\u00a0Jean-Fran\u00e7ois Hamon<\/strong>, who is also a loyal client.<\/p>\n

A non-stop solo transatlantic in spring is no small feat. Approaching 63, weren\u2019t you tempted to enter double-handed?<\/strong>
\nI loved racing double-handed, but\u00a0I\u2019ve discovered I really enjoy sailing solo<\/strong>. It\u2019s not that I\u2019m a natural loner, but I easily find my rhythm, I\u2019m not constrained by watch systems. Believe it or not, I manage to read more solo than double-handed! That said, you need a great autopilot and everything to work perfectly because boats have become faster, plane much earlier and require more anticipation.\u00a0The keel really starts to whistle from 13\u201314 knots, it\u2019s a bit more stressful<\/strong>. Hopefully I won\u2019t regret it!<\/p>\n

“We\u2019ve pushed the limits
\nwhile maintaining versatility”<\/strong><\/em><\/span><\/h2>\n

In\u00a0your account<\/a>\u00a0of the Spi Ouest-France, you said it was incredibly close with the Sam Manuard-designed Pogo RC (the designer is racing the Cap Martinique double-handed with Erwan Le M\u00e9n\u00e9, and one Pogo RC is entered solo, skippered by Pascal Coret) and the Sun Fast 3300. Can you outline the strengths and weaknesses of each?<\/strong>
\nI\u2019d say the Sun Fast is one step behind because there\u2019s a generational gap.\u00a0This Verdier design was the first IRC boat to adopt a fuller bow shape<\/strong>, with a reverse sheer under the transom, giving a lot of hull power. We followed with the JPK 10.30 and then\u00a0Lann Ael 3<\/em>, the Pogo RC prototype, came out. They went even further with a fairly radical hull and we saw that it worked better. On the JPK 10.50, with our in-house designer Jacques Valer,\u00a0we pushed the boundaries while maintaining versatility<\/strong>. We\u2019re often a bit better upwind than the Pogo, but they\u2019re very comfortable downwind, especially as they\u2019ve increased their sail plan with more square-top mainsails and bigger spinnakers. Logically they should be ahead, but\u00a0the question is whether they\u2019ll save their rating<\/strong>. They still owe us 30 minutes a day\u2026<\/p>\n

You mentioned improved performance, but boat prices have also risen significantly: \u20ac280,000 for a JPK 10.50. How do you explain that?<\/strong>
\nIt\u2019s true, we\u2019ve increased by more than \u20ac70,000 compared to the JPK 10.30.\u00a0The boats are more technical<\/strong>. The sandwich core is now Corecell rather than Herex as it uses less resin, the standard mast is carbon, the rudders are lifting on JP3 bearings\u2026 But\u00a0most of the difference comes from labour<\/strong>\u00a0because the composite work is more refined. We\u2019ve gone back to vacuum laminating instead of infusion on many parts to reduce resin content, and there\u2019s no structural bonding flange. All joints are done by hand.\u00a0It\u2019s getting close to Class40 construction standards<\/strong>. In the end, we save over 200kg on the platform, but we\u2019ve gone from 1,100 to 1,400 working hours.<\/p>\n

“Since the JPK 1010,
\nwe\u2019ve only made the right choices”<\/em><\/span><\/h2>\n

There were 60 boats at the start of the Cap Martinique in 2024, 48 this year. Could this drop be explained by the price and technical level of the boats?<\/strong>
\nHonestly, I don\u2019t think so. We\u2019re still producing one JPK 10.50 per month,\u00a0demand is there and this race inspires a lot of experienced amateurs<\/strong>. There were actually 65 pre-entries a year ago, but the organisers recorded quite a few withdrawals. Some for medical reasons because there are a lot of boxes to tick, others, I think, due to the economic climate.\u00a0There are many SME owners in this race\u2019s audience and the current period isn\u2019t easy<\/strong>, with a lot of uncertainty. When things get tighter at work, it\u2019s not necessarily the right time to go sailing.<\/p>\n

Which clearly isn\u2019t your case!<\/strong>
\nI\u2019m lucky to be in a strong market segment<\/strong>\u00a0and surrounded by\u00a0a great team<\/a>, including Jean-Baptiste Dejeanty who supports Jacques\u00a0(Valer)<\/em>\u00a0very well. We\u2019re close to 60 people at JPK, the yard is doing well and\u00a0I\u2019m starting to think about succession<\/strong>. I\u2019ve received quite a few external offers\u00a0(to buy the company)<\/em>, but I haven\u2019t really looked at them because I\u2019d like it to happen internally. The expertise is there.<\/p>\n

When you launched the first JPK in 2003 (the 9.60), you came from windsurfing, with no legitimacy as a builder or sailor, working with an unknown and unconventional designer. What\u2019s the secret behind JPK\u2019s success story?<\/strong>
\nI probably had a lucky star and I always believed in it. As you say, I came a bit out of nowhere, but\u00a0I already had solid know-how at the time<\/strong>\u00a0because, alongside boards, the JPK brand was doing a lot of moulding and parts for offshore racing. I knew the qualities of Jacques\u2019 hulls and from there, imagination had no limits. It hasn\u2019t all been smooth sailing either. We tried some models that didn\u2019t work, but\u00a0since the JPK 1010, we\u2019ve only made the right choices<\/strong>\u00a0and entered a virtuous cycle. We\u2019ve diversified, with IRC boats but also fast cruisers and a bit of motor. When I retire, I think\u00a0I\u2019ll struggle not to stay involved in the design work<\/strong>, which is fantastic. I\u2019ll keep lending a hand!<\/p>\n
