Hi Sigurd, The foiling board is not really aimed at any existing board sector, it's an entity in its own right. It has been technically extremely...
Hi Doug, We have not progressed the dinghy at this stage as the foils are much better suited to a windsurfer application, particularly the...
Forgot to mention, the shape of the board is a reduction to just what is needed for foil and rig support and to act as a launch platform. It is a...
Just a flying visit: It looks draggy if you put all that in the water at once. You don't. It balances a bit like a unicycle on the large span...
Good video. Notice the persistance of the ventilation bubble after the surface has been breached. An observation similar to this led to the...
I have not spoken to Ovingtons, however, the economic situation here in the UK at present is not glowing (to put it politely, thanks Gordon...)...
It doesn't mind at all. The ventilation only has to overcome hydrostatic pressure which means that it remains nice and progressive as it moves out...
Tcubed and Sigurd, This is possibly the aspect of this foil that I have most trouble getting across. Sigurd has it about right however....
You are describing a surface piercing set up here. The Tomahawk foil is surface running. When fully ventilated and at design incidence all the...
I don't want to get in the way of a good fight, but often point out, when enthusiasms start to get in the way, that the art of engineering is...
Sigurd, "seriously, if it is a foil, the makers of it must be completely retarded" Thanks, I will put this on my CV;) IT IS A PROTOTYPE!...
A few vidclips of monofoil tests (and a couple of crashes) here, if you are interested: http://www.youtube.com/user/HowesAero Jon
Good to hear that you are all enjoying my latest headache. The foil section was developed for Monofoil, use on a dinghy and then on a board...
"What ever happened to the monofoil? Did it ever get built? I believe the trash in the Gulf would destroy anything at 100mph. I hear of boats...
Thanks for the enquiry, no bl**dy money at present so working on other projects to allow us to self-sponsor. I am buliding a larger model at...
Sigurd, 1: It is inclined 2: The arm can generate downforce, upforce, or no force, depends on the needs of the course sailed. 3: Both...
Ventilated foil section I have attached three files. The first, "Basic Foil", is simply the output of my 2D design programme, this gives the...
Superventilating foil I will try to post an image of the section and its coordinates, not now, it is too late at night! It is actually quite...
Some thoughts on this, without any guarantee of being correct! Monofoil has two key features that are relevant here: 1: A free feathering,...
Tom, Thanks for your detailed response. "Even a closed lifting surface, like a loop, leaves a vortex wake." I am not sure that my answer...
