The Bombora X-IT was supposed to use the stepped bottom to track better according to a mate who reckoned it needed a smaller fin. Never had any proof though.

what about how the Starboard Hypersonic ?
did it steer well with short fins ?

That's a MAD bottom shape. Did they go ok?

i had the original one (105l). Great in light winds and upwind, like a mini formula. But for me it had very frustratingly low top speed. Far too much drag I recon. Normal manovouers were not an issue.

In these videos: 5.9m KA Kontrol (Koyote) in barely 12-13 knots of breeze. (Way back on 2008 we didnt have high res cameras.

)

I have seen pics years ago of experimental boards made with similar exaggerated vee, trying to get them to work without conventional fins. Nothing seemes to have stuck.

I had one of those too for a while. I dont think it really did much except slow it down with more drag.

Yes, but that is on an Easterly in the 'Boat Hole'. That too is not as good now as it has filled up with sand a bit, but you can get a nice window of good depth tide for an hour or so.

Yes, same spot in both vids. But the SW bank was EPIC back then. The spit was flat to the ocean! Laminar wind flow!
