zeus foil 5-6 knot

Hello. That's what zeusfoil promises. The idea is good, for example, horue was offered a biplane. sometimes when the wind blows 7 knots, I do not have enough for takeoff and I wait for a gust of 8-9 knots.


The "LWing" ?Our lightwind machine ... The "Lwing". The "Lwing" is a wing "embedded" on the mast of the foil and helps the whole system to "take off" (earlier than a conventional foil) when the wind is low ( from 5 .. 6 kts).
No need pumping !! ( Additional pumping helps more !!! )
The embedded wing in combination with the main front wing produces the required lift for early planning and take off. When the system reaches a high point , the rider starts foiling firstly with the gravity without the contribution of the embedded wing. When reaches a speed above critical (meaning ... above "the stalling speed") can continue to foil on a normal way. During foiling the embedded wing does not contributes . It is out of the water !!! It is so cool !!! Try it !!?(Jibing : During the jibe , the system can be easily controllable even if the embedded wing dives below the sea level. ) (For best results , the mast need to be more than 80 .. 85cm . (Our Aluminum mast : 88cm))

Interesting idea.

I am taking it one step further with "no pump" low wind foiling. I have 2 BoostFins on order (20 lbs. thrust each). Mount on the US FIN box in parallel next to the deep tuttle foil mast. Using the wrist mount wireless remote, it should be able to drive the board on to plane/foil, with little to no pumping.

For the same reason I never favored the infamous foil fin, I'm not really jazzed by the Zeus idea. The additional lift is too far back essentially forcing the nose down when it's below the water which makes you have to push down with the back foot even more. Add to it that you get this discontinuous lift as the foil rises and falls, and I imagine it would be a pain to foil in any swell or chop with it if not also in flat water.

Having used a ++ style of fuse, I find that light air favors having the center of lift further forward for early flight. Or, the easy thing of just using a bigger front wing.

I'm willing to be proved wrong, though.

Drilling holes in the mast at 4 points does not seem like a great idea !!! to start flying at 5 or 6 knots (or 10) without pumping is impossible! Hearing this makes newcomers frustrated trying! Anyone who foils regularly knows!

They can reinforce the mast for that, but yeah it can't be an afterthought.

Would be interesting seeing some video. Was out yesterday on 900cm2 front, 95cm wide, 9.0 and the wind dropped to 6knots or so. I was able to feel just the cusp of power and then pump like a maniac. Almost pulled it off, but got gassed right as the board was releasing each time. Were the most extreme light wind conditions I had given real effort to. Had to wait for more like 8-10 knots to go without killing myself.

If that would have doubled the lift, seems like it would have happened. I'm also thinking of the underwater kicking hazard. I try to keep track of where my foil wings are to keep from ever kicking them and that would complicate it a bit.

Hmmm, fun concept, but I'm not sure it'd help very much. 5-6knot claim seems exaggerated. There are videos on their website www.zeusfoils.com/lwing-videos
Video 1 shows some pumping, and it looks winder than 6 knots, that's for sure.

Video 3 shows anemometer reading of 11.8 knots. This is solid foiling territory on most setups, so not very convincing.


On the other hand the Boostfin idea sounds fun - keen to hear how it goes

I'm with you seeing the white caps in the background. If that's their 5-6, I'm fully powered in those conditions. As for video 3, I'd be willing to bet that some of my bigger friends could foil a 5.7 or 6.0 with a Moses 1100 or SS i99 no problems. If you need to bolt on extra area, the Horue biplane was a better solution but a bigger wing was still better. Their XXLW was amazing but I could never figure out how to make it turn.
