Yeah. You get the impression that the ierofoil guys saw the way forwards when they released their V2 amphidrome that could be configured to work as a directional as well as twin tip canard design. Tough market to break into.

I understand the problems they face though. Its pretty difficult to get positive PR. You can't just pass them off to inexperienced foilers as they'd struggle just to ride, and any experience foiler would be comparing it to efficient designs so wouldn't see any benefits over the existing designs but would see the drawbacks.

Can someone actually cite a strength of a bidirectional foil? Is there actually any justification for this? Is the idea to prevent having to learn how to gybe or tack so that you can be a kook just bringing your kite over the top at 12 oclock every time you want to change direction like someone on their first twin-tip lesson?

I want to hear someone who is a really good kiteboarder tell me why this is the right way to go hydrofoiling, because as far as I can tell, this design hydrofoil is analogous to this design of airplane:

Bolting one of these to an unmodified twinny to learn how to foil seems like a good way to break both your board and your ankles, all without really learning how to foil.

A local guy who used to do a lot of long distance kiting on a TT looked into one of the bi directional foils as a way to be able to carry a foil in a backpack and be able to swap between depending on water depths on one of his mega treks. He tried for a long time to be able to mast the thing (and he is a good kiter) and eventually broke it....without ever mastering it. He now rides a Moses.

Well, I think nothing2seehere is spot on, and like you imply in above too cwood.

I understand the problems they face though. Its pretty difficult to get positive PR. You can't just pass them off to inexperienced foilers as they'd struggle just to ride, and any experience foiler would be comparing it to efficient designs so wouldn't see any benefits over the existing designs but would see the drawbacks.

It works actually pretty okay, the TT foil.

But as it is "chosen" by non directional riders with little experience maybe, they will struggle to learn.

And riders who CAN ride hydrofoils, would never use a TT foil because it, as you says, will not have the same perfect balance, nor be as efficient so only disadvantages yes.

BUT, it will work just fine indeed - the thing is just, that noone is ever gonna appreciate these because of above I would think :roll:

At this point of time the immediate future of foiling is towards waves. Which sort of goes against putting any effort into a TT based foil.
Being able to push foiling further into barrels and bigger surf. That’s worth some effort.

If twin tip boards were not available in kiteboarding, I doubt it would become so popular. Bi-directional foil has much more appeal to TT riders - believe it or not, but they don't want to jibe, no matter how awesome you think it feels!

I'm actually excited about these new foils, even though I'm happy with my traditional setups. It is nice that someone puts time and money into this research. Plus, it is the most affordable option out of all existing attempts so far. At $450 I'm not sure if Dan makes any money at all! Hopefully we will hear more reports from real users of the new foil, rather then more opinions on why it shouldn't exist :naughty:

The problem is he's only done half the job. Without the clever way of bolting onto a twin tip non-destructively, its still another board you need in your quiver. The ierofoil solution (sold by takoon now) was clever because the stiffness you lost in having a flexy twin tip was partially compensated by the cradle that clipped onto the board.

That idea of 'if the wind drops off I'll just clip a foil onto the bottom of my board' is an appealing idea. I'd have bought one if it wasn't double the cost of a regular foil. The guy with the $450 foils should license the fitting system for a complete product.
