What about folding props like with RC powered gliders.  The props collapse along fuselage laying flat.

Did you hear what we witnessed out at the point last week?  They were all riding toeside.

Does anyone foil waves and switch feet?
...

Yes!   Your customer Westendorf reported wings flying in harmony on the point for the first time Evah!

Really cool. 

And Yes I will be switching feet.

Then this.  One week later.  Windy day 15 to 22 (maybe 25)

16.9 miles on the foil. I am feeling comfortable on Regular Foot sailing port tack.  6.4 Slingshot v2 WITH A HARNESS (Than you DW).  GoFoil Maliko 200.  Big Slow Wing.   

Wing blowing Southeast.  Switching feet.  The only time I go "Toeside" is when jibing and not switching my feet.  Toe-Side is ridiculous.  Utterly insane.  I could see 'maybe' going toeside with the sail fully luffed when riding a wave.  Otherwise in flat water TOTALLY INEFFICIENT.  Learn how to switch your feet.

After the self rescue I needed a little bit of recovery.  So I packed up my gear, on my bicycle, and peddled to the other side of the point.  To hide from the current.

Successful Dry hair Session.  With the boom and the Duotone managed to jibe without falling in (ever, not once).

If I hadn't hit the Morgan Point Lighthouse I would have gone across the Mystic River to Enders Island.  Doesn't look far but it would have been a 9 mile loop (in Purple) to get back home.  My iWatch was NOT yet activated.  Lesson learned.

More on that next.

Wind picked up.  I was on the backup wing.  5.0 Duotone.

Planned out the session.  This means doing calculations on wind, current and WTF can go wrong.

Things almost went very wrong.   I had to self rescue when the current was dragging me East and then the wind shifted from Westerly to Northwest and started blowing me towards Rhode Island. 

1 - Sailed to the South
2- Pointed North, wind shifted North West
3- Very Quick puff meant I could point up and hit the Morgan Point Lighthouse.  Thanks to Jesus
4- I paddeld laying on the board for 3/4 of a mile upwind for 45 minutes to Esker point
5- I ran home in bare-feet for 1.3 miles

Arse kicked licking wounds

I am witnessing that it is the Prone guys that are causing all the mayhem.

1) We on SUP's can't get multiple waves as easily

2) The prone guys tend to be the Agro people that generally hated SUP and therefore wouldn't even think to try SUP foiling. 

PS: When I am foiling in a crowd I generally takeoff and run way, way wide.  I will tell the better surfers that they can take all the inside they want. I want nothing to do with the whitewater.  And lets face it OLD fashioned surfboards are GLUED to the whitewater.  We can fly 50 or 100 yards down the should and turn, turn, turn.  When they run out of steam we can come back and then hit the whitewater.

I guess we're all jonesing for online foil content during that time when we can't go to the beach and we're supposed to be working. 
. . .  So then the guy who seemed to own the lineup for the last several years sees a good set wave and tells me:  "Let's go".  I'm like, no you go ahead - and he says "no I want to see what that thing can do."

I am on the East Coast Connecticut and Rhode Island.  It is FLAT, FLAT, FLAT with regular forecasts of 0.5 - 1.0 ft.  The forecast for tomorrow is JUMPING 2 to 3 feet. GREEN.

So I am the guy from California that surfs 100+ sessions a year at Pillar Point in Half Moon Bay.  I regularly show up with Ruby this summer and we are totally alone surfing 2 to 3 foot waves.  On one particularly small day one of the locals asks "How was it?"  "1 to 2 feet I respond."  He looks at our rental car with Illinois plates, we are in Rhode Island, and says "You drive all the way from Illinois for these crappy 1 to 2 foot waves."  I just laughed.   

On a slightly bigger day I didn't have to film or edit.  A doctor named Ed shot this video and sent it to me.  Classic summertime New England foiling and still SUPER fun.

Golf Bag and a paddle bag with Bass Pro Fishing patch sewn on the paddle bag.

Paddle Bag - Great idea!

I plan to put my Duotone boom in my foil board bag.  I think it should fit.

GoPro finally released their editing software for the GoPro MAX. 

Here is a digital re-master of a 500 yard ride at Mavericks.  The season is back upon us.  Maybe someone will join me this fall.

L41 7' 4" SUP with GoFoil GL140.  Buoys were 11 feet @ 14 seconds.  This was a 15 to 18 foot take off.  Last ride of the day first on a foil.

Back in the days of windsurfing the fastest finish on fins was a 400 grit sanding.

It had something to do with SLOWING down the flow at the boundary layer and the subsequent layers would shear up to the freestream.  If flow got too fast at the boundary there could be separation.  Separation caused higher drag than the shear between the layers.

What is a good source for coiled leashes?  Ideally I just want the leash material but I have been down that road before.

With all these darn leashes everywhere I am finding the coiled leash to be a huge advantage.

Essentially we only need the board leash in case of rare separation.  It doesn't need to be too strong.  Accept maybe when I get back into the waves.

Foil SUP / Re: Can We Talk Stabilizer Geometry?

« on: August 29, 2020, 07:59:20 AM »

Said another way:  There is a Lot Going on with wing Camber, Lift, Horseshoe Vortices (Downwash), AOA and Stabilizers.

Stabilizers Are Training Wheels

Like grandma holding a railing going down a flight of steps we use Stabilizers to make ourselves feel Comfortable flying at our skill level. 

The better we get the less we need them.  The smaller they become and the shorter the length from center of lift to stabilizing platform. 

A flying wing is inherently unstable (typically because the center of mass is behind the center of lift).  We are using Mass shifting instead of control surfaces to manage pitch stability.  Similar to a hang glider.  But we are all still beginners with just a few years of experience. 

2 years ago I took the stabilizer OFF and it flew.  A little bit pitchy but I even managed to pump.  This was only my 3 attempt behind a tiny little boat.

Here comes some Adminsplaining . 
The method of measuring angle mentioned in the vid below (Bill does something similar) is useful provided a few things. 
https://www.youtube.com/watch?v=jTCyag5N_vE

I am late to the discussion.  While I like the video I think George from Delta Hydrofoil is measuring the angle relative to the Chord line not the ZERO lift Angle of Attack (AOA).

On a Symmetric foil the Chord = ZERO Lift AOA.  With a Cambered foil, flat bottom curved top Cessna wing or Maliko foil, the Zero Lift AOA can be Negative Five Degrees or more.  So these angles can all be shifted by +5 degrees by the Camber of the specific foils.

https://en.wikipedia.org/wiki/Zero-lift_axis

Here is an image of Negative Angle of Attack = Zero Lift = No Downwash.  The Stabilizer lives in this downwash.  Even if the Stabilizer were at ZERO degrees relative to the front Wing and was Symmetric it effectively creates down force.
