Everything that's old is new again. Like to hear what the experts think of this folly.

smells like a "Kanard" (i think thats how it was spelt),good on them for thinking outside the box! only way things will advance,personally i think it's abit of joke on their part.

Hey Choco, pretty sure it was "canard". Great wave fins back in the mid 80's but as slow as a wet week. Im pretty sure Multi Fins sold a squillion of the buggers.

the bottom right fin is very similar to the gsport lightwind formula fin. just a little smaller i guess.

Yes folly. The fins were bad the last time this was tried and so making something slower but less likely to spin out was good - 20 years ago!

I can see they may be useful for those tiny free ride fins.
Many years ago I experimented with a rotating canard, it had heaps of grunt, but was a pain to make, so I didn't continue with it very long.
