Fly the Wing - Take off the Stabilizer

Can a long foil still have an airfoil profile? Like NACA?

[SURFFOILS]

Yes it can , due to the length of the chord it can have a longer, more stable wing profile of greater NACA foil, or be completely flat or both.

Or a Combination as I’ve done on this foil prototype where the body has a long glider wing NACA profile for slow speed lift and the wingtips are flat like a surfboard fin for speed on the steep face. I should have faired the 2 profiles together but that’s for another prototype.
 Note 50/50 rounded leading edge for wider AOA, and chord apex moved back for less drag/higher speeds

Went out the other day to test a new larger tail wing.  Waves were 4-6 ft, not too big, nice shape for foiling.  I came off the board early in the session , hitting the foil . nothing new, no harm done.   Paddled back out. For the next 3 waves I was convinced I had forgot how foil.  try as I might, I could not get the foil to lift.  I kept moving back till, bam , foil lifted and I was completely out of control.  Never have I been so frustrated with foiling.  Being unusually slow that day, I finally had an inclination to check my rig under the board.  The new tail wing had snapped clean off.  No f---ing wonder. I now have an amazing appreciation for the importance of that little wing that up to that point was almost inconsequential.  Paddled in. put on my old tail wing, and proceeded to have a very good day of foiling.  Never did find that wing.  Good thing they are cheap to make.

No stab video. Impressive tricks.

[SURFFOILS]

So no tail wing and a swept front foil. It looks stable as he’s got great control over it.
You can’t have people foiling on a single foil as the rear foil is essential to keeping the trim angle of the front foil.

oh boy--clearly kite foiling is going to head to the amazing--soon there will be huge waves, airs and craziness--the video shows the skills are there for this--at least the featured kitefoilist has the skills--if his gnuts clank like steel, he's ready to get wild

not sure how big the foil market will be, but if you consider the beginning of WS, vs the wild shit they do now (despite that wave-sailing is a tiny market), imagine what will be done with foils in a few years.............

gon be very cool--i'll enjoy watching from the sidelines!
