Extrapolated from the JPK 960, the JPK 110 combines the qualities of its "little brother" with those of a true ocean cruiser.
Light and planing but seaworthy and powerful, the JPK 110 has a large hull volume to envisage a real "life on board" on a very powerful, safe, easy and seaworthy sailing boat.
Winner of the last Spi Ouest France, the JPK 110 is also a formidable competitor.

An ambitious programme
Consistency of programmes. Effective in regattas; easy in cruising.
Today, the IRC rule predominates in most regattas. This rule favours boats with relatively little sail area (low overlapping jib) and relatively heavy weight. To go fast with little sail, the wetted area must be reduced but this is a handicap to stability. The solution is to compensate for the loss of shape stability by the weight ratio. To obtain a good weight ratio without reaching a too penalizing overall weight, the construction must be accurate, rigid and light. Only infusion can achieve the right hull weight to ballast weight ratio.
Very well balanced, the boat is therefore efficient in an upwind breeze but fast in all conditions as it drags little water.
When cruising, it is the real comfort under sail because the geometry of the rig, the fittings and the stiffness of the canvas make it a very forgiving boat. But all this only works with a good design.
Jacques VALER has designed a hull that is wide at the deck but thin at the waterline. The forward sections are in a pronounced V shape, quite deep with an advanced hull depth. The mid and rear sections flare out over a long, tight arch. Very comfortable upwind due to its ballast ratio and forward sections, the boat remains planing downwind in the breeze.
- Using the infusion process
- Hull and deck in 19 mm balsa sandwich
- Four-axis fabrics 850 gr and UD 600 gr
- ISO polyester resin for the first layer and ortho for the structure
- The flats are infused at the same time as the planking for greater homogeneity
- The birch plywood partitions are laminated to the hull with bi-axial fabrics
