What you are referring to is called Ventilation. When air got sucked in through the strut to the fin.droffats wrote:...not sure but it might have something to do with the phenom of air getting sucked down along the leading edge. I've seen some video of it on moth hydrofoil sailboats I think. The vertical part of the setup sucks air down causing turbulence or reducing lift or both (?)
I've asked the same question and that is what someone pointed me to. I haven't yet been able to confirm it with a foil designer though...
Why do you say/think most foils are ridden in super flat water ???windfreak74 wrote:It seems to me that foils are the light wind wepon of choice but i wonder what would be lost by loosing 20 cms of keel lenght. most foills are ridden in super flat wáter.
this question comes from seeing that most of the time foils are 30 cms in wáter and the other 60 cms on air.is this really needed?
torque wise the 90 cm length makes the keel more prone woble or breaking.
is this assumption correct?
Im want to build one from scrap and learn!
thanks for sharing.
Definitely, mine is pretty "long".KristianE86 wrote:Have anyone experimented with increasing the distance between the foils for increased stability at (high) speed?
