X-Over

Showing all 5 results

The X-Over foil offers accessibility to beginner foilers and enormous potential to the most experienced ones.

The X-Over range is placed between the Rise and the Curve. Its large surface area offers the lift and ease of the Rise and its more moderate thickness accepts a speed close to that of the Curve.

The secret to this versatility is simple: a low ratio that is maneuverable, fast and forgiving. A cocktail of qualities that boost confidence and therefore performance.

What the L’Ours has designed with the X-Over is a low ratio without a performance ceiling. By drastically reducing the thickness, we obtain excellent glide and speed. But by keeping the surface, you get a foil that flies very easily and with control.

If this foil is called X-Over, (pronounced Cross-Over), it is simply because this foil is very versatile. It adapts to all foiling practices, be it wing, surf, SUP or kite foiling.

The front wing is available in 4 sizes (M, L, XL and XXL) and the stab in 2 sizes (42 and 46 cm) in order to adapt to all riders and all disciplines: surf foil, SUP foil, kite foil and wing foil.

Our front wing X-Over range

Several foil sizes adapt to different sizes and different speeds:

  • In small sizes from M to L, depending on your own size, it is ideal for getting into kite foiling and surf foiling on a gentle set-up that allows you to progress crescendo.
  • In large sizes from XL to XXL, depending on your own size, it is a reassuring front wing for a sporty beginner in wing foiling or surf foiling. It is particularly appreciated for its tolerance in the badly controlled beginners phases but also its speed as well as its maneuverability in the later phases with more experience.

The shape of the front wing

The shape of this range is all about the surface area. This is its big strong point: a large downforce that allows you to fly very early on compact and therefore reactive wings.

The profile is quite thin (in proportion to the large chord, it is even very thin) but the maximum thickness is advanced in order to take off early and easily, then to accelerate. It is necessary for a lot of efficiency at low speed, and to saturate as late as possible in top speed.
Seen from the front, the X-Over is almost flat to get the most performance possible. The user of these wings will be able to manage their height and hook back if necessary.

In few points

  • A large surface area that allows you to fly almost immediately and effortlessly thanks to a large support. This surface also saves you from oversizing and having to take a wing with a lot of wingspan that will be less maneuverable. The wing is compact which is a guarantee of maneuverability.
  • A profile with an advanced chord for maximum forgiveness in the low range, making it easier to learn, maneuver, and take off early.
  • A fairly thin profile (in proportion to the large chord, it is even very thin) but advanced which gives it a lot of efficiency at low speed, without saturating as soon as the speed increases.
  • Slight upward twisting of the tips which makes it easier to place the wing into the curve for a “lighter” rail to rail underfoot.
  • Supercritical profile as on all our wings to improve its glide.
  • The X-Over is less arched than the Rise which makes it easier to recover from stalls for a healthier general behavior.

  • The shank / profile connection fillets have been optimized for better hydrodynamics.
  • The fitting area is minimalist and does not require any deformation of the profile to be adapted. The profile is perfect right down to the fuselage.

Our stab X-Over range

The shape of the stab

The fitting which allows the connection of the stab to the fuselage is longer than on the other models. The stab is further away from the Front Wing. This increase in the wheelbase gives longitudinal stability to the X-Over foil and facilitates trim management to ensure your first flights and then work on your first maneuvers.

The winglets at 90° to the profile are pronounced to stabilize the foil in direction (yaw), and limit steering and crabbing. The foil will naturally be placed in the axis for maximum efficiency and to facilitate learning.

In few points

  • A large surface area characteristic of the X-Over range for a lot of lift.
  • A thin profile so as not to saturate at high speed.
  • The winglets at 90 ° to the profile are pronounced to stabilize the foil in direction (yaw) and limit steering and crabbing. The foil will naturally position itself in the axis for maximum efficiency and facilitate learning.
  • The shank on the fuselage is longer than on other models of stabs. The stab is thus further from the Front Wing, the wheelbase is increased and therefore the longitudinal stability as well.
  • The shank / profile connection fillets have been optimized for better hydrodynamics.
