Gong foil for windfoil

[lecum]

Hi
I want to consult if someone has used a gong foil in a freeride windsurfing board. My idea is to use windfoil with small sails and a lot of lift, small mast (65cm) and big wing. Early planning and slow speed. I only weight 70 kg.
Could anyone tell me he has tried it? Any recommendation?
Thanks

Le monsieur (l'Ours) il a dit que c'était en dernier qu'il s'occupait du foil windsurf.
Les différentes sorties de cette année, les foils, les surfs, les sups ...
il n'a pas chômé et pas mal embauché.
J'espère pour nous qu'il ne va pas atteindre pas son niveau d'incompétence
A trop grossir ...
Merci

I don't think it gas been tried with the Gong foil, but it has been done with similar foils, so it should work.

Note that I have only seen SUP foil boards with an added mast foot, see my posts at http://www.gongsup.com/forum/viewtopic. ... 81#p120981
I never read of people putting foil boxes in windsurfing boards in a position centered enough for a SUP foil.

Hi Colas

Thanks for your answer. Could you recommend me the best gong foil stuff (all the components) for my windfoil approach? I prefer a short mast to be able to do beach start, priority is planning with very few knots and small sails (5,3) and easy learning and jibing, more confort than speed and performances. I weight 70 kg and my windsurfing board would be a freeride one with tuttle box, 120 litres.

i'm skilled in wavesailing.

Merci beaucoup.

I weight 70 kg and my windsurfing board would be a freeride one with tuttle box, 120 litres.

Note that the existing tuttle box fin will be too far back for a SUP/surf foil.

I do not know if it is doable anyways, I guess by raking the sail backwards a lot to bring the center of sail power above the foil.

On the size I do not know. I would tend to use a "normal" wing (M or L) to lessen the forces on the gear, but I really do not know.

OK, thanks. Only to clarify, I would never use this board for sup or surf foil, only for windfoil

Yes, That's what I understood. I was thus stressing the point that the existing tuttle box will be too far back for a foil designed for SUP or surf foiling, and that I see no example of people using this combo.

Also, from what I read, tuttle boxes installed for sailboard fins will fail sooner or later, they are not reinforced enough to support the forward torque (the lift on the foil wing acts as if as if you pushed on the fin from behind) and the deck will fold upwards in front of the box. Fin boxes on sailboards are reinforced againt lateral pressures and hitting the bottom, but the foil pushes the other way.

Hi again colas

Could you tell me the advantages and disadvantages of a long and a short mast for sup foil?

The forces are bigger with the long mast?
Learning is more difficult with long mast?

At the moment I prefer the short one (45 cm) but don't know if it has any disadvantages later.

Thanks.

At the moment I prefer the short one (45 cm) but don't know if it has any disadvantages later.

The short mast is better for learning:
- forces have less leverage, so the "jackknifing" falls are slower and less violent
- if you fall on the foil, it is less likely to be on the face
- falls are softer, you fall from lower altitudes
- if you breach the surface, the fall is gentler, and is easier to recover
- you can foil in shallower waters, where the smaller waves are

However, once you get the lateral balance, a shorter mast has only disadvantages and is not used anymore:
- the height range for flying is very small (between touching water and breaching) and it is harder to fly long rides
- it is nearly impossible to fly in chop, which reduces this height range, or in imperfect waves
- a longer mast amplifies the speed given to the wing when rocking the board for the take off, which is very useful once you know how to foil.

Basically you use the 45cm for the first sessions until you have good lateral balance on the foil, and the sell it or keep for teatching friends or family.

Hi Coolas

Apart from the foi issue. Could you tell me someone with experience to put a mast foot in a new Karmen 7'11" FSP near the basque country? I'm about to buy a Karmen 7'11" FSP but I want to have one reinforced screw female on the board to be able to attach a windsurfing sail and surf small waves in 10-15 knots.

My previous SUP boards had it and it's useful to continue in the water if the SUP session is spoilt by a sudden wind increase.

Thanks.

[coolas]

I don't know. You have a list of repairers that are cool at: http://www.gongsup.com/forum/viewtopic. ... 77&p=62364
There are plenty of repairers in the basque country, but I do not know the ones that are familiar with Windsurfing gear.

I suggest however that you contact the gong team to see if they could install it at the Gong SAV before shipping, that may be the best solution, they could even do it before installing the pad...

[lecum]

I've already consulted to Luca, but he's told me no. Who should I contact in gong to get what you say? It would be the best solution for me. There are other manufacturers who include it.

[coolas]

Luca is a new member of the team, he may not have occurred to him at the time to have the "After Sales Service & Workshop" (aka "Gong SAV" in French) do it for a fee, because it is actually a (next door) separate team.

Just re-contact him or the [email protected] email

I had them install prior to shipping a central fin box on a SUP that available with only a quad setup for instance.

Hello Lecum,

our shaper is going on holidays for a month therefore I advised you to do this modification at a local shaper. All the shaper they know how to do this modification. To help you we can give you an extra pad and pass you all the info about where to put it.

Best regards.

Hello luca

Thanks. It's a pity. However I don't have many shapers in the surroundings with this kind of knowledge. They don't know how to get the piece to install in the SUP board in order to screw the mast base on it. I should get this piece on my own!!

Besides it's a piece which has to be installed reinforced without any damage to the surface of a new board. I know many cases in which the sail has gone out breaking the board surface. I don't trust any shaper.

Could you at least tell me where to get the piece, and how much would it be the additional cost if I wait until Gong shaper is back?

Thanks.
