The current TKF Manta strut section is like this:

The one on the photo from Revhed above is the old model i guess.

The Zeeko mast has 3 bolt extrusions which means 3 x 8mm bolts fixing it to mount plate.

I have not seen the Zeeko profile, maybe someone can post a pict?

Happy to post one when I get it if nobody else does.

When I tried the Slingshot aluminum mast with Stringy Wings, it wasn't a good combination. I do however know quite a few people who like their SS masts with the Hoverglide wings. If I was going to get a SS mast, I would probably ride the SS wings too.
I don't see why this should be the case - the only thing I can think of is the mast was incorrectly mounted on the fuselage, e.g. too far forward or backwards, or that it's too short or too long. Otherwise I can't see how it would be a bad combination as such.

You can add the RL Variofoil mast to the list.
Depending on chosen mast length, the mast price range from 30 euros (30 cm) to 105 euros (115cm).
To this you can add 185eu for a base plate or 95 eu for a KFbox stub

The airfoil section looks like the EPPLER E837 thinned down from original 16 % to 12 % (13mm/107mm)
EPPLER E837 HYDROFOIL AIRFOIL (e837-il) from airfoiltools.com (see "Applications/Airfoil Plotter" which allows to decrease any profile thickness to chord ratio)

E837 12% from original E837 16% thinned down by a 75% factor (12/16). Used to be the Zeeko mast airfoil section in 2012 according to designer.

I always wondered what it would cost per piece to send the airfoil section cordinates to a manufacturer for 50 or100 pieces in 90 cm length. :o

That looks to be dimensionally identical to the TKF Manta strut??

I can only talk about the LF masts, that are the ones I’ve used.
I would stay away from the orange one. It fills with water, while the blue one doesn’t.

Of course... because I was the designer for zeeko foils from 2012 to 2014 till I started thekitefoil.com that became mantafoils and Europ2 / RL surely know well my masts profiles...

for info, we have till date 2 profiles... on used on manta 1 which is same as our current windfoil mast (14.8mm) and a second one which is 2016-2017 kite profile (13mm).

you can buy them cheap here:
http://www.mantafoils.com/e-shop/Parts- ... 3DpriceAsc

and yes it is e837 modified... a very good mast profile that I used on zeeko 2012 model first... I saw several brands who also started to use it lately for their carbon high end race foils...
