Foil SUP / Shits and giggles/River wave foiling
« on: January 19, 2021, 10:22:57 AM »
Never has this wave come up so often.  It only lasts a few days to a week at a time but always gives me the chance to test new designs.   Sorry if the you tube link does not work.  Itís been a while and I always forget just what to do every time I try to post.

I have less than a handful of successful tacks behind me but was curious whether or not a large, thick lower aspect wing is any better or worse than a thin, high aspect wing.  Just want to better my chances going forward.  I have used both and do not seem to have any greater success with one over the other.

I'm really not sure where to post this but since my whole foiling attention is now on winging, I thought it might as well be here.  As some of you  know, I live in Maine.  Northern Maine to be more specific.  Foiling here is very much in its infancy even though this is my third year of appreciating its many joys.  Its even harder to believe that the only foils I have ever flown have been of my own creation.  Well that all changed last night when a future foiling/wingfoiling buddy brought his new Naish Hover 95l board(damn is that thing light)and his 1650 foil set up.  No wind, so we decided to continue his training behind my boat in hopes of getting him accustomed to his new rig.  Getting towed behind the boat on his Naish rig opened my eyes to the variance in foil design.  The Naish 1650 definitely was fun to fly and also very agile but I could not get over the fact that its top end speed was very, I mean very,  noticeable.  I could barely apply enough front foot pressure to keep that wing from breaching at higher(17-20 mph?).  This is entirely new to me except for the very first foils I made.  Upon looking and measuring the washout, It seemed like the Naish foil had maybe .5 degree or so.  This being my only explanation.  My last 3 wings offer none of this excess lift at even 20-25 mph, the limit of my little outboard.   While the Naish foil offered great low speed glide, its upper end speed seemed hemmed in and a lot less forgiving.  Is this normal for most production wings at higher speeds?  I just feel that wingfoing needs a foil that will allow great lift at lower speeds and not too much lift at higher speeds.   Still working on my next 52" wide +/- ultra high aspect wingfoiling wing experiment in hopes that these questions may be answered.  Until then I will enjoy the wings I have made, even more-so now.

Just did a relatively long search of the forum posts and am still wondering if anybody has been able to affix a length of carbon fiber to a F-one swing so that it is firm and rigid.  The handles on the Swing are so flimsy so I feel I will need to make some sort of frame out of foam blocks or carbon fiber.  I've only used the 6M and feel the handles are not quite right in their position.  I have an extendable carbon paddle shaft which would be perfect.  Just wondering.  Thanks in advance.

Wingsurfing, Windfoiling, Wingfoiling, Wing SUP / Twisted wings anyone?
« on: August 14, 2020, 05:20:50 AM »
I have a Gong Wing 7M that has a definite twist in the last wing segments on one side.  Almost 5 degrees.  Having made my own wings, I can understand how easy it is to get the angles correct and symmetrical.  I'm really not sure if one side is twisted down or the other side is twisted up.  It does make certain maneuvers like tacking a little hard on one side versus the other side.  The wing just doesn't want to roll over very easily.  I've emailed Gong Galaxy but have yet to receive a response.  Has anyone else noticed this when viewing their inflated wing on the flat ground and does it really make a difference?  I will try to post a pic, but don't count on it since I usually struggle with that sort of thing.  Thanks all

A friend of mine who does not foil is interested in trying a wing to get onto waves versus a paddle while using his 9'6" SUP board.  I told him I would give him some tips and he could use my wings.   I thought it might work but  figured someone out there has had some experience with this, good or bad.  Any tips would help even if that tip includes-  "Its not worth the effort".

I swear, if I had to choose between foiling good waves or winging.  Id choose winging!  Its a hoot!  Well, last nights session left me crawling up a particularly rocky portion of the more than beautiful Maine coast to get back to my car.  Deflated the wing and just pushed the board with wing on top.  Didn't take very long but in the process I forgot to reinsert the valve caps.  Yes, you guessed it.  Got about 1-3 cups of salt water in my bladder.  Having never done any sports with an inflatable bladder, I am wondering if there is a problem (and not with my brain) with getting salt water inside a bladder.  Any advice would be appreciated.  Thanks in advance!

I'm relatively new to this wing foiling game but I'm hooked,  This shit is way too much fun and gets more fun every time I do it.  just starting to get my offside starts and runs.  Cant do switch stance yet but I hope to some day. 
The purpose of this thread is to ask the "long timers" just how closely they stick to the recommended pressures in their wings.  My homemade wing is of such large diameter that I probably do not need as much pressure and I also do not want to fully test my sewing skills.  My new wings say 8-10 psi max.  I live in Maine where the water tends to be very cold so if I put 10 psi in, once in the water it probably decrease to 8 upon cooling.  Should I go to 11 0r 12 psi and make sure I get it in the water quick(no hot sun).  Just curious.   I keep thinking there probably is a fairly wide safety margin between best pressures and boom pressures.  I would also imagine some of you have gone above the stated recommendations to gain additional stiffness and got away with it.  Thanks in advance.

Foil SUP / Short fuselage opinions
« on: March 30, 2020, 12:20:55 PM »
I am redesigning my fuselage.  More in line with the Axis foils set up except for it being full carbon ( old carbon fiber hockey stick filled with solid carbon).   Just curious. Iím wondering if making the fuse shorter will help with pumping.  Already planning on a smaller tail wing.  Iím pretty sure Iíll just have multiple tail wing mounts on the fuselage which will allow me some room for experimentation.  Thanks in advance
Stay well, be safe, Foil on!

Wingsurfing, Windfoiling, Wingfoiling, Wing SUP / DIY Kite Wings Anyone?
« on: November 11, 2019, 06:05:18 AM »
Just curious.  Anyone else out there trying?  I made one, which at 3.6 M is too small for the types of wind we get in Maine.  Currently making a 5M .  It is not easy!  Maybe I do it just to grow some neurons. Being such a new sport, I can see there being so many improvements to current gear in the not too distant future.

Wingsurfing, Windfoiling, Wingfoiling, Wing SUP / DIY kite wing
« on: April 16, 2019, 05:14:22 AM »
I have many old kitesurfing kites and am plan on cutting them up to fabricate a kite wing based upon Duotone, Ozone, and or Naish kitewing types.  Any information to add to the current brain storm in my head would be appreciated.  That just looks like the perfect tool for Maine, where the beaches are few and the winds are many.

Foil SUP / possible E-foil project?
« on: March 08, 2019, 07:02:34 AM »
While at a second hand store the other day I picked up a working fishing trolling motor for $15.  I figured, what the heck?  It may give me enough thrust to at least get my big wing up and flying, its the right size, shape, ......?

Has anyone ever tried using an electric motor like this to create an e-foil?   Just have to figure out the control mechanism required to turn it on and off.  Possibly a cable or wire to a trigger in my hand.

Foil SUP / Wing shaping and wing washout
« on: February 20, 2019, 12:34:01 PM »
Yes, I know, What the hell does this mean?
I am making a new wing(41"W x 9" cord) in hopes of downwinding and if I get good enough, some paddle assisted flatwater takeoffs.  As I sit here and ponder the wing segments glued to my anhedral form I can not help but wonder if I would benefit from having some washout at the wing tips.

What is washout, you ask?  Washout is when the wing tips are slightly twisted down to decrease the angle of incidence  when compared to the root of the wing.  If all wing segments are in the same angle of incidence, there is no washout. 
Washout is used in airplanes to decrease sudden stall in low speed situations. Though in the world of hydroplanes, there may be no benefit. 

I am wondering if anyone has ever taken the time to notice whether or not the angle of incidence of their wings root is identical to the angle of incidence of the wing tip.  To do this one would have to use a level and place it on the middle of an upturned wing exactly for and aft. Make it so the level reads level by altering the boards position.  The more difficult part is to place the level in an absolutely parallel position to the middle line of the wing, but this time near the wings tip(3"from tip)?)  Are the measurements level or does the level now angle up ever so slightly(down when surfing)?

Just curious, as I have always made my wings with no washout.   I would love to hear from those more knowledgable in aerodynamics and hydrodynamics. My guess is most wings have no washout and I will just have to experiment or, more probably, stick with what I know.

Foil SUP / Anyone with experience with bi-concave wings?
« on: January 22, 2019, 05:21:28 AM »
You know Da Kine.  There is a slight amount of double barrel concave on either side of the fuselage.  At the present time I cant seem to recall which companies produce such wings but Slingshot and Signature wings come to mind.  I up here in Maine and do not get to see any production wings in person.  The only production wing I have met in person is the Naish Thrust.   If any body has any experience riding this wing design and can compare it to non-bi-concave wings I would love to hear all about it.    Thank in advance!

Foil SUP / Changing cord to thickness ratios from wing root to wing tip
« on: January 21, 2019, 08:28:03 AM »
There has got to be someone out there who has information regarding this topic.   I am in the process of making a very large( 42" wide) downwind wing for my measly 155 lb body weight.   I also hope this wing will allow me to flatwater SUP start, eventually.  I have often wondered if decreasing the cord:thickeness ratio starting from wing root and decreasing towards wing tip would help with regards to increasing maneuverability of these XL wings.  Not sure if I want to go there.  For example, Wing root- NACA 4416 down to wing tip, NACA 4414.  Just a thought.  maybe it would lessen the outer wing torque against your feet?  Just wondereing.
