Our team of specialists has been working since 2014 on the development of ProFOIL.F1 and its evolution.
We put all the expertise, the technicality and the SELECT experience to serving an objective: to create a highperformance windfoil, easy and self-stabilizing, able to fly in an ultra light wind.
Experience & state-of-the-art technology
Constantly improving the level of performance and sailing comfort, our products are subject to constant optimization.
For some years now, we have integrated a large team of specialists in the development of our foils.
The research and development team is made up of some very qualified and highly experienced enthusiasts in the fields of fluid mechanics and technical engineering.
Technological evolution, recent developments and permanent feedback from our testers allow us to improve our products constantly.
The ProFOIL.F1 SELECT, is the modern version of the windfoil.
To achieve this, we have developed the construction of all the components of a foil designed for windsurfing.
The construction of a windfoil is extremely complex and high-tech. Because of the considerable forces at work, all components require perfect development, production and skill.
The ProFOIL.F1 is a concentrate of our expertise in hydrodynamics and the use of composite materials. It has been developed and manufactured as a real piece of aeronautics. Designed with rigour and without any concession from the quality that has made the reputation of SELECT / SM COMPOSITE.
Maximum performances for light wind
A locked mast / fuselage assembly :
The mast and the fuselage are the structure of the foil. The quality of these two parts is of paramount importance for obtaining the best performance of the front wing and the stabilizer. The composite structure must be as elaborate as possible to hold the twisting and bending. This is the essential condition to gain stability, which will determine control and performance.
Low drag :
The minimal drag of the ProFOIL.F1 is the component for which nothing is left to chance. The choice of the mast profile, the shape of the fuselage and especially the recess of the wings and stabilizers are without equivalent compared with other foils on the market.
Perfect surfaces :
The preparation of the surfaces is the condition of the performance of all wings, mast and fuselage. All composite pieces are sanded in five steps to achieve the best factor of water on water gliding. Our parts are bare, without primer, without paint or varnish which impose an unnecessary load and often conceal faults.
Length : 90cm
The ProFOIL.F1 mast / fuselage assembly can be dismantled.
The mast has a tapered flange which gives 20 mm more (back and front) than the maximum width of the mast.
The form of this base added to the high modulus carbon reinforcements enables you to obtain the best holding when twisting.
• Technology : full carbon single piece. Made in metal moulds.
The ProFOIL.F1 mast is a single piece full carbon structure: consisting of fibre UD high modulus 390 GPA HM and carbon biaxial 430 GPA HM. (NB: The sandwich does not have its place on a mast of 90cm > the risks of delamination are too great).
• Finishing : sanding / Grain 1200 > optimization of the water on water gliding.
• FixatioN : fixing to the fuselage: screws and stainless steel plugs / safety restraint.
Connexion plates :
The 2 «connection plates» (CP) are the safety components that connect the foil to the board in all circumstances.
The «CP TOP» distributes the clamping forces on the deck.
The «CP bottom» (under the hull) limits the front/rear movement to optimize the stability of the foil.
Technological evolution, recent developments and feedback from our testers have
resulted in the completion of new Aero aluminium fuselages.
This ultra-rigid alloy specific to aeronautics makes it possible to maintain the twisting essential to the good performance of the wings whilst reducing production costs.
In the end, you get an equally powerful ProFOIL.F1 at a more attractive retail price.
Its geometry is upgradable : it depends on both the mechanical forces and the hydrodynamic optimization.
- The section is very square for limit twisting.
- The finer rear part holds the foil in yaw for better balance.
2 fuselages available for the ProFOIL F.1 :
The 890 fuselage promote manoeuvrability : 89cm is the optimal length to create the best balance of forces between the main wing and the stabilizer with excellent manoeuvrability.
The fuselage 1060 promotes longitudinal stability. (for long tacks)
The lengthening of the fuselage makes it possible to increase the spacing between the main wing and the stabilizer for greater stability and even higher performance upwind.
IMPORTANT : CATHODIC PROTECTION SYSTEM
The sacrificial anodes must be periodically inspected and replaced when consumed
The front wing is the carrying surface for taking off and accelerating.
The wings of the ProFOIL.F1 are pre-twisted on the ends to reduce drag as the speed increases. They are equipped with a gull wing dihedral for 2 reasons:
1 – It concentrates the flow for more control. This increases longitudinal and transversal stability.
2 – The ends of the wings are lower: they increase the list by favouring performance of the end of the wing which is more isolated from the surface of the water.
The ProFOIL.F1 wings have a powerful profile with a high reserve of acceleration.
The sanded finish on the appendices limits untimely take-offs, making the control of the foil more predictable.
• Technology : manufactured in carbon (full carbon prepreg), they transmit the power instantly.
• Finish : sanding / Grain 1200 > optimization of the water on water gliding to make the profiles work over wide
ranges of perfomance.
• Fixation : 3 stainless steel screws / 6 mm diameter / 7Nm torque.
2 models available for the ProFOIL.F1 : W.850 and W.750.
Front Wing 750 / Length : 75 cm / Surface : 769 cm² / For riders between 60 and 80 Kg
Front Wing 850 / Length : 85 cm / Surface 866 cm² / For riders between 80 and 105 Kg
Stabilizer / The center piece to obtain a perfectly suitable foil for your board.
The ProFOIL.F1 generates a strong power developed by the front wing.
For safety reasons but especially so that the stabilizer can bring the stability necessary for the evolution of the foil, the design calculations hydrodynamics of the ProFOIL.F1 make it a nose-down foil : which is to say that the generated power must not pull the front wing out of the water whatever the conditions.
The role of the stabilizer is to regulate the horizontal seating of the foil.
The distribution of the weight, the weight of the rider and the sailing thrust of the rig are also to be taken into account to manage the horizontal seating of the foil as best as possible.
The scale and the angles of adjustments are complex parameters whose balance is crucial to obtain a effective stabilizer : SELECT has made the choice of the best ratio between speed and comfort of sailing.
The wing / stabilizer assemblies of the ProFOIL.F1 are pre-set to promote the optimum horizontal seating generating the least drag.
• Technology : Carbon Fr4 > High precision machining
• Finishing : sanding / grain 1200
• Fixation : 2 stainless steel screws / 6 mm diameter / 7Nm torque.
IMPORTANT : The stabilizer must be chosen depending on the type of boa
EVO stabilizers are to be used on freeride and slalom boards.
PRO stabilizers are to be used on dedicated windfoil boards
IMPORTANT :The stabilizer must be chosen depending on the type of board used and the weight of the rider.
