The J/Boat Difference

Build quality = sailing pleasure

Sailing the seas, carving out a fine wake, manoeuvring easily, making fast headway… then dropping anchor in a bay fringed with white sand. Making the most of the beautifully crafted modern fit-out combining solid wood and white gloss bulkheads illuminated by natural light. Herein lies the pleasure of sailing and life aboard a J/Boat, a yacht built with care, with a concern for lightweight yet robust quality design.

What is the difference between a fast and a standard cruising yacht? The manufacturing quality and the construction materials of course! These two parameters define the weight and stiffness of the build, in order to offer up a yacht with increased rigidity and generate improved performance when sailing (+20%). The upshot of this is less use of the engine for the great delight of everyone aboard. Another benefit of a well-crafted construction is that it ages well hence the second-hand value remains buoyant!

To achieve this, the boat’s construction methods utilise the infusion process pioneered by J/Boats. Some 30 years ago, the SCRIMP patent (Seemann Composite Resin Infusion Molding Process) was applied for in the construction of J/Boats, which was a revolution among shipyards. Today, this well-controlled technique is more widely known as ‘infusion’.

What is infusion ?

Sandwich construction using infusion methods is one of the most technological and cutting-edge processes in the marine construction market. With traditional lamination, an operator applies the resin to the materials by hand. With infusion, there is less human contact with the resin, hence working conditions are improved and there is better quantity control. In practical terms, having applied various layers of materials, or even added elements of predominantly foam-based sandwich, a plastic cover is stretched tightly across the materials, creating a hermetic seal. A pump sucks up any air between the cover and the materials, compressing these in the process. The compression creates suction and the resin is distributed around the materials, followed by a few hours’ wait for the polymerisation process to be completed. Result: better for the environment, perfect distribution of the resin and optimum quantity, culminating in light and stiff decks, structural bulkheads and hull.

At J/Composites (builder of J/Boats), all the aforementioned elements are created using the infusion technique so as to obtain maximum stiffness. Furthermore, all the secondary bulkheads are bonded to the hull and deck throughout, as well as to the fit-out structure. It should also be highlighted that the scantlings of the infused composite structure meet the standards for offshore racing (World Sailing structural plan review), which is possible thanks to the very significant weight saving synonymous with infusion. In short, this is construction at its best !

From a block of wood to marine furniture

Night falls over the anchorage. The lights of the yachts are dotted about beneath the canopy of heaven and it’s time to rest easy. Two or three cabins equipped with vast double bunks await you… just like at home. Note the finish on the solid wood carpentry. At J Composites, craftsmanship is still part and parcel of the fit-out on its yachts. Every piece of furniture starts off as a block of specially selected walnut. No reconstituted Alpi-style wood here, only solid wood in its original state. As such, the boat ages naturally and looks even more beautiful over time! A great deal of work goes into the selection process to ensure only the best pieces of wood are chosen. Carpenters and cabinet makers use it for lockers, cupboards, shelving, and tables adapted to each yacht interior, like the Elégance range penned by Roséo.

Comprehensive and well-proportioned deck hardware

The fun of slipping along, long runs under asymmetric spinnaker from one island to the next, at high speed…! Isn’t it essential to have all the necessary equipment as standard for making headway on every point of sail? A trademark of the J/Composites yard, the famous retractable carbon bowsprit with spinnaker fittings comes as standard of course. The hardware is optimised to the boat in the Elegance and Sport series and developed jointly between the builder and the supplier. For example, the new Snubbair winch developed for the J/70 or the aluminium mast on the J/112 E and the J/99, are fully developed for these models with notable innovations. With regards to the deck hardware, it’s worth noting the size 40 winches on the 4mt J/97 E or J/99, which are identical on an Océanis 46.1 with an equivalent weight of 11mt!

The air flows through the cabin and in the utmost comfort you’re already dreaming… Your mind is filled with images of cruises with family or simple double-handed sailing, coloured by the thrill of slipping along under spinnaker, easy manoeuvres, a gentle, light helm, a meal with friends in the warm, modern saloon, echoing a nomadic life at sea albeit in absolute comfort. You’re on a high-quality yacht which will be a part of your dreams for a long time to come!
