H 16 Anti-Pitch Hydrofoil

Did you make a set and how?

How thick are the units please?

I cut a snow board ($10. at a thrift store) in thirds and then secured the front and back thirds of the board with screws and Home Depot metal 2 inch "L" brackets into the tip of each hull. I originally made it for the H-16 I had and it REALLY worked Great = popped the hull out of the water within the first six inches of the tip being submerged. When I sold the 16 I took them off and put them on my Getaway. Truthfully I never got the hulls on the Getaway to submerge = it's that stable and the hulls are bigger have lots more air in them than the 16 did. I would send you a picture but it's snowing here and the boat is covered and in an outdoor storage yard.

Ok, so they hated these over at the beachcats forum.

But, they seem to actually work for us.

The ones from Hobie are 55 square inches.
The ones I made (and I forgot to mention that I did cut a "V" in them to interface with the hull) they are 183.5 square inches.
Almost three and a half times the size of Hobie's.
And the tips of the hulls don't dip down more than 6 inches before they pop right back up !!!
Never had them act in reverse like someone mentioned.
Because the tips of the snowboard are angled upwards and "maybe" create a vacuum/dead spot on top = the same way an airplane wing does (Bernoulli's Principle) which causes a wing to rise regardless of the angle of attack of the wing.
Maybe ??? Maybe not = either explanation is irrelevant = THEY DEFINITELY DO WORK !!!!!!!!!!!!!!!!!!!!
I did post a picture of them somewhere on the Hobie Forum website after I made them.

Sorry - I could not find the picture I took of them in my list of posts on this Forum.
