OVERVIEW

Up- and Downwind are the preferred racing angles of this specific foin sail design. With this very stable and easy controllable sail your concentration can stay fully focused on the tactics. The stronger the wind the more you'll feel like - wow, this sail has a wide range of use! Just keep racing on the same size when others desperately rush back to the beach to rig their smaller sails.

SPECS

SHAPE

LUFF CURVE
Foiling is a smooth sport. The sail and the body position is not effected by the movement of the chop and therefore don't need a lot of twist and reflex on mast and luffcurve. The straighter luffcurve has the weight centred more over the base plate and makes the sail feel light and manouvrable.

OUTLINE
The high aspect ratio makes the Foil+ highly efficient like a narrow blade cutting trough the air. Perfect aerodynamics are the key to success in foil racing.

LOOSE LEECH
Avery tight leech at the two battens above the boom keeps the power within the sail for early planing and upwind angle. A slight increasing loose leech troughout the middle towards the top releases just enough pressure to ensure the top speed.

CAMBERS & SPACERS
A metal bracket prevents squashing the edge of the sail body. With a choice of six different camber sizes (length/diametre) we achieve the optimal camber pressure for sail body stability while maintaining a smooth camber rotation. The additional spacers give the opportunity for the individual rider to fine tune the sail to his individual needs.

CONSTRUCTION

Racing is a "no-compromise" art in Patrik's dictionary. Everything is optimized with peak performance in mind.
The main panels are 5 MIL clear monofilm in boom area and then 4 MIL in the upper sail body.
Why use clear monofilm? Because this material is few grams lighter than its colored alternative and gives the most direct feel in accelleration and topspeed.
For the foot panel and a minimalistic area around the clew we kept a good impact resistance 5 MIL red x-ply materials. That are is often stressed when your sail rubs on the deck grip of the ultra-wide racing boards. Along the leech, you find again 5 MIL (closer to the clew) and 4 MIL (closer to the top) clear x-ply to keep the rear edge of the sail stable and aerodynamically clean even in hi-wind choppy conditions.
All the panels inside the mast sleeve are made by the thickest monofilm available which provides the best stiffness and a locked profile where the main shape is. For the mast sleeve itself we reduced the amount of PE fabric material (which absorbs tiny amounts of water) and maximized the 2 MIL x/scrim-ply area instead, which is super light but still with the highest number of wires/m2: so it's perfect for spreading the load among the whole sail body.

All these tweaks create a pure foil racing sail that is stable on the flight and provides with all the controlled power you need to win modern foil races in challenging light wind conditions.

TRIM

The Foil+ needs a good amount of downhaul force to create the needed stability on the sail body.
The suggested loose leech amount is indicated by connecting an imaginary line through the black/white color transition on the batten pockets. Make sure you don't put too much downhaul so the leech is still closed above the boom to allow the sail to pull you upwind.
