Component/material quality The loads in an X-yacht are considerable – even more so because of the large sail plan. The strong hull and keel structure require the rigging components to be top of the line and dimensioned correctly. Only the best suppliers are used: Andersen, Harken, Reckmann and Spinlock provide reliable rig components that are easy to use and maintain, and correctly sized for the loads involved.

As a boat yard defining itself as a premium brand, X-Yachts has refined and defined their DNA into a list of items called “X qualities”. Here are the most important:
Steel frame The galvanised steel frame is the most famous signature feature in an X-yacht. It has been a core principle since 1981. The frame provides a safe, strong attachment between the keel and the hull and makes it possible to add more ballast, a key part of the inherent stability that X-Yachts are so famous for. The keel is bolted directly to the steel frame and any force working on the keel – even sudden shocks from grounding or hitting debris in the water – will be absorbed and distributed more evenly through the structure.
Stability/weight distribution X-Yachts has always prioritised high stability by maintaining a low centre of gravity. But longitudinal weight distribution is also important in a sailing yacht. Excessive weight in the bow and stern will cause pitching and slamming. This is not only uncomfortable, but also transmits massive loads through the boat and slows
it down. Moving tanks and other heavy items closer to the centre of gravity reduces inertia and increases both speed and comfort when going through waves.
Laminate quality, clear gelcoat The strength and integrity of a composite structure relies on a complete saturation of the fibres. To make it easier to detect potential dry spots or air bubbles during production, X-Yachts applies clear gelcoat on the bottom section of every hull.
Encapsulated keel X-Yachts’ cast iron and lead keels are encapsulated in a reinforced epoxy e-glass shell, to guarantee a fair finish. The shell ensures that every keel stays accurate and faithful to the designed, original profile, and protects the keel from corrosion.
Vacuum infused epoxy sandwich Vacuum infusion makes it possible to control the amount and distribution of resin very precisely and produces a uniform, strong hull with an approximate 15 per cent weight reduction. Gurit Corecell M foam is used between the two layers of laminate, a sandwich material with excellent impact resistance, high strength and low resin uptake. This build process produces a very light, stiff and strong hull.
The aft end of the cockpit is enclosed and the transom folds down from an aft deck that serves as a helm seat

Centre lift X-Yachts are designed to be lifted using a single lift point integrated in the steel frame. This means there’s no need for straps at the crane, which eliminates the risk of damage to propellers and rudders. Also, there’s no scratching of topsides or removing of freshly painted antifouling. The single lift point makes things a bit easier when hauling out or launching the boat.
Design, hull lines X-Yachts’ design office has a more than 40-year-long track record designing yachts that are known all over the world for their efficient lines and fast hulls. They have always taken pride in doing their design work inhouse, and continue to do so today.
Ergonomics, easy handling Behind an easy and free flowing experience of sail handling in the cockpit lies an extensive attention to detail when it comes to ergonomics and work positions. X-Yachts are well-known for easy handling, and their racing heritage means that they know where deck gear needs to sit to make things work as effortless as possible – not only for efficient high- performance sailing, but also for relaxed shorthanded cruising.
Lead keel bulbs Lead keel bulbs have a smaller volume than iron bulbs of the same weight. The use of lead in bulbs means a 30 per cent reduction of volume. Less wetted surface means less resistance and more speed.
Stiffness and rig tension On any yacht, the forestay and backstay will pull the hull upwards while the mast will push it downwards. If the hull isn’t stiff enough, the boat will flex – especially when sailing upwind in waves. This causes the forestay to lose tension momentarily every time the boat hits a wave. It’s called forestay pumping and it deforms the headsail at a critical moment. X-Yachts’ solution is to build precisely engineered structures inside the hull that enhance its stiffness. This prevents forestay pumping and ensures that tuning adjustments of sails or rig are precisely transferred. Being able to adapt easily to changing conditions makes the boat perform well and makesit a safer and more enjoyable place to be.
