Foil SUP / Re: A few questions?

« on: May 06, 2022, 03:22:18 PM »

If your getting up fine then getting over baked you need a  faster wing, not because a smaller  wing will make less lift but because it will get you out in front of the critical section out to the shoulder.

I live on the east coast with garbage waves (Florida is a surf destination for us) and I ride a 1000 at 220 lbs.  I wouldt grab a wing that small out the get go but there’s a reason almost  every company makes something semi high aspect at 37” wide and 1100 to 1400 sq cm (lift 170, Naish 1240, gofoil 1150, uni hyper 170).  Armstrong stupidly doesn’t have anything like this because armie had to be special and jump from the too slow/low aspect HS series straight to that ridiculous monster 1125 HA but screw that gear it’s trash anyways.

Pilars + divinycell + carbon deck and bottom.  Trick is the d cell goes all the way to the front foot.  That’s it.  If it stops shy it’s dead.

Did the math and this board is going on 1000 miles on wave hard pumping prone, hard groundings 220 lbs have killed 3 foils with this board plus 1 gofoil front wing.

0 flex.  I can stand on the board and wrench the foil full strength and no movement.  Sit on the wing with a buddy feeling for flex on the bottom and nothing.  That’s the real test….if it flexes at all that means eventually it will fail.  Sitting test is a good one.  Think about all the power going in through the front foot on hard pump through the board into the foil.

@Dontsink

Its going to be too thinn.  My last board i went from a 3" board to 2" and beefed up the construction and it still wasn't stiff enough  -  Stiffness is thickness sqared - provided there's a good connection between the 2 sides.   

For a given layup a 1" board is going to have 4X the flex of a 2" board and 9X the flex of a 3" board.  The reason kiters can get away with those lunch trays is they're not relying on pumping for power.  I kited a 1" lunch tray for years, giving it all kinds of abuse, but as soon as i started wave kiting and brought that pump cadence to my kite foiling (pumping through tacks, sneaking extra upwind lines on waves) that board died almost immediately.

Thats not to say its not going to be strong enough - you can add that extra carbon and absorb the load but it will never be stiff as a 2" board.    Ex. Wakeboards are very strong but not stiff.

Get some divinycell - https://www.aircraftspruce.com/catalog/cmpages/divinycellfoam.php 2" 24x 48 blank would probably work but the 3" would be best.  I personally would never go thinner than 3 for something i'm going to be pumping hard.

Oho yea.  2x 6oz. Carbon  Plus a box patch under vacuum. Standard foil glassing.

My boards these days are solid divinycell with pilar boxes connecting deck and bottom.  I’m 220 lbs, hard pumper, run aground frequently at speed.  No issues with my boards.  Production stuff lasts less than 2 weeks in my hands.

Wingsurfing, Windfoiling, Wingfoiling, Wing SUP / Re: Why is Naish so un-mentioned on this forum

« on: April 13, 2022, 04:45:56 AM »

The new mast and connection is definately better, i can say that with authority because the old system was garbage.  If you break from a prior backwards compatible design there should be a significant improvement, i think they have achieved that here.  Not sure why they have the aluminum mast range though.  The low cost carbon is so close to the AL and so far from the high cost carbon there's alot of overlap on the bottom.

I flew the HA 1400 and 1240 wings on a few different custom setups (thats how bad the mast was).  They were...ok...  As far as designs they felt not amazing but in the ballpark of what i wanted from a high aspect.  If you never rode another high aspect it for sure felt amazing but they were nothing special - even 3 years ago when fresh - now they're way behind the curve.

I think the MA wings are, again, ballpark wings - naish put a wing in the ballpark of what the industry is asking for.  Does it do the mid aspect thing?  Yes.  But not better than anyone else's mid aspect. 

I feel like the new stuff has moved construction to ok (wing fuse connection still isn't great, stab connection isn't industry standard 30mm bottom mount) and design to probably a step down from OK (if your not moving forward your moving backward).

They're not good, much less great, at anything so why would we talk about them?

Its a great setup for price concious people new to the sport.  Any rider who knows their business is willing to spend an extra $500 to get something that has Good design or Good construciton - maybe both.

Located in chs, SC.  $800 plus shipping for the package.

NL has ad tips removed, GL had had a lot of sanding and fairing, short pedestal is faired and ground down but works.  Mast is missing some paint.

300 for everything but the mast.  DM for individual pricing.

« on: April 06, 2022, 04:48:15 AM »

One more.  Specs- 6’3 x 25” x 5 3/4”.   110 L

@SUPeter is that the lot at Popham?  Rode there a bunch last summer.  Always trying to sniff out some more foilers to ride with on my maine trips(visiting wife’s family in the summers)

That deep water energy there hits way different than here in SC, wave is moving much faster than our crumbles down south.  This type of board seems perfect for matching that speed on catch.  My micro prone stuff catches slow SC swell great, was miserable up there.

Also with that swell speed pumping back is a lot harder(covering a ton of distance on wave) so sacrificing pump for paddle seems fair.

Classifieds / Looking for small cheap wing for my kid to mess with on the beach

« on: March 26, 2022, 10:13:42 AM »

Looking for a 2 meter small cheap nothing wing.  My 6 year old expressed an interest in messing about with a wing and I want to encourage it, but not to the point of buying a real wing knowing she’s years away from real riding.

Prone Foiling, Surf foiling, Pump Foiling / Re: Slingshot 2020 WF-1

« on: March 24, 2022, 02:38:36 AM »

Strength isn’t the issue.  It’s flex and associated power loss.  I’ve seen many production boards appear fine but develop movement at the plate connection, making them un-pumpable.

At that thickness there's no way its stiff enough for agressive pumping.  Stiffness = thickness ^2.

Strength is less of an issue than stiffness.  Expecially after a few months it will be a wet noodle, even if it has all the carbon in the world.

The Shape Shack / Re: Load testing my prone setup

« on: March 21, 2022, 10:10:29 AM »

Results

My measurement points were Zero on the leading edge of the mast 3 in below the fuse connection, on the front wing right in front of the connection, on the fuse right before the rear wing, leading edge of the mast right infront of the plate, bottom of the board right infront of the plate, and finally a repeatable spot on the nose.

I'm showing 1.9 degrees of overall flex between the front wing and the front of the board.  1 degree of that is between the lower mast measurement and the front of the board.  .15 is in the mast itself, and .77 degrees of flex is in the fuse or fuse wing connection.

The Shape Shack / Load testing my prone setup

« on: March 21, 2022, 10:00:25 AM »

I was curious about flex in my prone setup.  I built this setup to Be the stiffest prone foil set up on the planet. Board is solid Divinycell blank with Pilar boxes and 2 x 6 oz carbon plus a few patches. 

I ran the following rig to 104 KG to simulate hard riding forces.  Rachet strap is providing tension, sandbag is just to stabilize the test.  I referenced off a spot on the mast 3mm from the fuse and took angle measurements in different areas before and after load.  I repeated once to ensure consistent results.

Pro-set makes a 2 part epoxy foam which I imagine is better than PU foam in the same way that epoxy resin is better than PU.  If I had a board build on the horizon that’s what I’d be buying and testing.
