Thatís great Clay, you really look like youíre enjoying it and in control.
 Itís a different world in a foil isnít it ?

Foil SUP / Re: The first foil ban?
« on: January 27, 2019, 12:40:17 AM »
Have surfed Bondi since around 73, itís always crowded, maybe a few small breaks are isolated in the early AM but itís a small beach and thereís 50 people paddling out in the dark every morning.
 Itís not the place to foil unless itís winter and blowing a gale.
This ban would cover all craft with foils, prone, SUP, kite, bodyboard.

The Signature Albatross Downwind foils have a very narrow chord...... but I found it has a pretty small seeet spot balance wise.
Whether foiling/surfing or just standing upright, the forces are vertically inline and aligned. When you lean, and despite the centripetal forces, thereís always the constant of gravity.
 As you lean further, the centre of balance moves further out to the side putting more pressure out to that side. You can check this by standing up and leaning to one side. One foot takes more weight despite the same contact area.
 On a foil it means that area across the span will dictate the balance when turning. If you reduce the fitting capabilities of the wing tip by changing the foil, area , AOA or chord and an/dihedral,  it will change the lift as you turn. This foil has a very small wingtip so itís exactly as Piros said that it has a small sweet spot because thereís not a lot of lift out on the wingtip.

Thanks for the information Clay and what an effort to edit all those clips together too. Thatís commitment to sharing.
 Edit: searching for the Garmin, I found thereís several versions. Is yours this model ?  Im not enjoying the Trace.

Thanks, Brett.

Clay, Itís very easy to listen to you, whether youíre going from a script or not I donít know.
 What the system you use that displays the angles and board information ?
 And your board looks like it has skinny rails on a thick board. How are you finding that as opposed to a full SUP rail ?
Thanks, Brett.

SUPeter, Iíve made surfboards since the mid 70ís and Iíve never seen such a comprehensive build of any surfcraft or component like yours. Sure thereís the cardboard  surfboards and crazy designs but your internal carbon struts are amazing. Congratulations on you ingenuity and dedication.

Foil SUP / Re: Fly the Wing - Take off the Stabilizer

So no tail wing and a swept front foil. It looks stable as heís got great control over it.
You canít have people foiling on a single foil as the rear foil is essential to keeping the trim angle of the front foil.

Pono, letís pull that thread. Are you saying that, for example, a mast should have a strong square tube center (or multiple tubes) and then a soft aerodynamic fairing maybe 3d printed or light fiberglass shell

If so, whatís your proposed size for that to get the strength? I could see 3-4 1/2Ē square tubes being a mast but I canít see that being stronger than the current aluminum masts unless it was way thicker than they are now. Now, could a mast be an inch thick? Iíd like to know because then weíre getting to where we could have some real structural integrity. A 1Ē square, heavy walled aluminum square tube welded to a base plate would be damn hard to bend.

Now... where the number of my buddy with the machine shop? Iíve really been ignoring those race car builder friends for too long apparently. ;)


A 1 inch thick mast isnít going to create a greater -ve difference in performance if itís short enough. And in fact a thicker section has a lot of low speed and AOA advantages. And the height above the water is really for Ďmedia showí and not performance. In fact  being closer to the water allows the rails to be used in high speed turns that arenít yet part of foiling but soon will be.
Gee I hope in a year or two when everyone is low level foiling and dipping the surface for drag they remember these posts of mine,

Here it is...
 They redesigned a Slingshot foil.

Looks about 45 deg sweep.

Hi Fishman,the cameras on the nose facing backwards.i only did several videos to see how the foils rides in the water and how much mast flex there was.
 That video was of a dozen beach tubes and I had to stay high in the tube to prevent the foil hitting the sand. I really donít foil with anyone else but if I had a Red Bull film crew Iíd be able to get better video and stills.

Interesting that these computer geeks designed a foil even more raked back than the Fanatic Aero.

Foil SUP / 3-D printed foils.

 itís always interesting to see what computer guys who surf come up with.

https://www.javelin-tech.com/blog/2017/08/3d-printed-hydrofoil-project-intro/

Has anyone else tried printing a foil ?

Foil SUP / Re: Possible foiling banned in the U.S.
« on: November 27, 2018, 12:37:49 AM »
Hi SCB, I think itís more of a litigious reaction to the clear potential of what happens when foil meets child.
 Not that itís a Ďclear and present dangerí but it only takes one example to make a precedence that law should have pre-emptied.
 I got the word from a CA foiler.
 Itís the sort of thing that could be fake news but could be the rumblings of a decision that ends foiling in public recreation areas.
I hope not.
 As for the popularity, while  thereís an amount of people who foil or make their own foils and post about it,  thereís also a lot that foil but donít post or wish to share.

You guys never heard of me until a year ago and yet Iíve made over 300 foils over 13 years.
Im currently in discussion with one of the guys here to make a foil for Mavs so I believe thereís a lot of interest thatís not showing on the radar, because itís happening in the background.
And Iím sure surfboard manufacturers would be looking to improve their customer base by expanding into new territory with technology they already understand. Witness how many new foil makers have popped up in the past 2 years ?
Are they all new companies or spinoffs of similar industry players ?

Foil SUP / Possible foiling banned in the U.S.
« on: November 26, 2018, 03:34:50 AM »
Has anyone else heard the rumour that foiling could be banned or limited to specific areas due to the danger to other water users ? I heard it in Ca.
 Itís a kinda left field rumour but it does have some substance in that foiling is globally and exponentially popular and has few constraints on its useage.
 Thereís very few injuries but there is a small scare factor with the mast and wings.

Foil SUP / Re: Finally all Foils available
« on: November 22, 2018, 10:52:14 PM »
I'd like to see Tuttle boxes go away, I think mast tracks make more sense, but purpose-built foil boards will compensate for the design limitations rather than switching to a better solution. Inertia that comes all the way from windsurfing boards that already had a Tuttle and a lot of strength.

+1 Bill. The Tuttle needs to go.
