Hi
Its been time consuming to say the least! Maybe 60 hours including making plug, mold, then solid carbon.
But happy with the result, will have to spend more time on the rear wing, make it a little thinner.
Still got to convert old windsurfer to foilboard. And sink a tuttle box in.
Panicing about the foil falling off the board?? Might put a leash on the top to the board some how, untill I know its going no where.
But will it work???

That looks great. You have a lot into it. How did you design the wings and determine the spacing between them?

I made a wooden version first, then it broken! So re thought the weak part and fuse length, plus everybody's plans and input from the forum.
Fingers crossed it works, it's all hell stiff and ridged though, we will see.

Looking good Scuba :thumb:

The only thing that might make it not work, could be the angle between the wings.
Well, AOA relative that is...

If you have made it just like most other foils, it will work, for sure :rollgrin:

Distance between, position on board etc. is not important, only trim details - but the AOA has to be within the "operational" range I am sure :naughty:

And no, I have not tested what that range is... Also dependant of your profile/camber choices and washout or not etc.
Some are putting washers on the front and rear screw of their tailswing, to find their "most liked" AOA, but I havent done that myself...

Thanks guys
I think I will start off with both wings at zero pitch and then add shims to the rear wing to add negative pitch (leading edge pitched down away from the board) might be the way to go.

Might be best to velcro a float onto the tail of the board and have a thin kite line from it under the tail to the mast?

Idea is that if the mast rips out, it pulls the float off rather than breaks the cord or you have the foil flying after you on a leash.

Do you have any pictures of the wood one that broke? How long did it last?

I was thinking of building a wood foil to try some things out the possibly build a glass or carbon one.
