Hi Sup Foilers,
In my attempt to catch waves on my JP Australia 7.0 115 Ltr board ( Large NP Foil) I have tried everything in my capacity. No problem to balance and move around but catching bumps have been lately catching waves.

Not was I was hoping.

The waves are steep and during wipeouts the gear and me gets beaten up.

How to catch the smaller waves or better bumps? I paddle as hard as I possibly can (Feels like I will break my carbon paddle soon) timing is obviously key.

In my quest to pop up and foil like "all others" on YouTube I have tried to trim or setup my foil, position and board.

1. The wedge (About 10mm on the back) Helped a lot on my first try with it.

2. Moving the foil Fwd seems to shorten the board? Pivot point (Foil) I can move forward as well balance the pressure point. When I have had the foil fully aft in the track I have had little luck getting on the foil. Frustration as on my normal 9,6 Sup I would not have any of these problem catching the wave. Think the 10mm wedge helped a lot as it felt like having a sea anchor holding me back.

3. To further increase lift I have trimmed the back wing.

4. Front foot strap are just in my way, I think one day I will have it installed for lifting during pumping at the start.

Maybe I need a larger down wind foil? I do not want to end up in surf to be able to foil, some manufactures recommend not to use the larger foils.To much stress on their equipment and could void their warrantees.

Where to go for these larger foils? Armstrong CF2400, GoFoilMaliko 280, Signature Albatross 210, Axis S-Series 102, Takuma V900. Hope that Neil Pryde will come out with a XL front wing But haven't heard any thing if or when that might be. Sent them a e-mail but no reply so far.

Anyone tested the above foils pros and cons to use the biggest ones on the market?

Cheers

Anders

Is it helping a Lot to wedge the Foil ?

Hey Filow,

Given the design pairing with JP and NP, I would be surprised if a wedge would be necessary to get more efficiency.

Moving your foil further forward on your board will effectively create less swing weight and a more neutral balance point. This is helpful for low power days, Dw'ing and when you are struggling to get up and stay up. However, this will work against you as the power comes on, making you have to ride very front foot heavy and potentially making the board feel a little harder to control because of the reduced swing (swing weight can help with directional stability and control at speed). So you need to know your gear.

Wedging is only useful if your board has too much tail rocker (i.e. not an actual foilboard, a modified board). I see so many boards out there flying nose down because they have wedged their foil, this makes pumping and powered control really hard. Ideally you want to be flying relatively level with the water when you are powered. Anything outside of this creates difficulty in trimming.

By all means play with different settings, try wedges if you have them, just be careful not too stall out your wing by getting too aggressive with your AoA. There is a distinct moment where the drag component will out weigh the lift component and you become very inefficient.

Good luck with it, ride heaps, make only small incremental changes, I see you're marking your board which is a great idea (I do this to all my boards), and only change one thing at a time. I always suggest moving the mast position first before anything, then rear wing angle, then lastly I would look at any wedging (which should not be necessary on a production setup).

Ride safe,

JB

I have had some better results with the wedge on catching waves, but there is limited lengths riding and I can't say if it feels like riding nose down.

Does Wedge and the Mast at the back of the board can help you get up on the foil on Flat water ?

I also have a JP 7'0 and a NP Large foil and I have struggled a lot in the beginning, without the wedge the foil was like an anchor, too much drag to get some paddle speed to catch small waves.
I made a wedge going from 0 mm to 6 mm, how thick is yours in the front Anders ? And how did you make it?
And how much do you weigh ?
With this wedge I catch small waves a little better than with my normal sup a Starboard Hypernut 7'2x28@106liter.
I tried downwinding but couldn't get flying ...had the foil all the way in front and the stab tilted , suppose the NP large is too small for my weight.
The NP XL wing comes in September but dont hold your breath Piros said.
I contacted JP about my AOA problems and they just said they had never heard of the problem...
I thought I had got myself a working JP/NP combination but I am a bit disappointed to put it mildly...

My wedge is made of 8 layers layers of plastic from ice cream boxes. I have my foil more to the front then in this picture nowadays.

I have ordered a Jimmy Lewis Flying V 5'10 x 28,5 @105 liter and a Gofoil Maliko 280 and 200. I hope this combo will workout off the box....

I think you have to be superfit,supergood and a lightweight to get up on this combo on flat water.
And you need a thick wedge of course
And the foil all the way back in the tracks is not good for pumping...

I had a friend cut a board down with a CNC machine. Not to sure of material but it should do for now. It is 1.5mm -12mm
My weight is about 76Kg

The flying V at 5?10 and a big wing Please post pictures and impressions when you have tried it. Would love a short board and big wing! Think that's the way to go.

So your wedge is 10,5 mm
Mine is only 6 mm

Did you try thicknesses?
My method is quite flexible, I can add or remove layers but 6 mm is working for me.

I had a wedge made from a plastic spatula and it was about 3 mm thick. I felt nothing and decided to make a rather large wedge.
Works for me now, with more experience I probably would not need it.

I am not familiar with that board or foil but a 1.5 -12mm wedge (so basically 10.5mm) seems excessive to me.

Are you sure you are not overdoing it?

I think I would be trying something a lot thinner, maybe further forward in the tracks if anything.


Don't be fooled by how easy some make it look to pop/pump up on smaller waves/bumps a lot of it comes down to experience and technique.

Get that back foot right back over (or just in front of) the mast.

JB makes a lot of sense with his comments.
What I think is that all gear is tested by profficient foil paddlers.
They have the ability to get up on a foil with much less effort than us beginners. So what I think is that they paddle the foil & not the board. That is they can probably get the foil Angle of attack more horizontal where as a beginner angle of attack whilst paddling would be more foil nose down unless the beginner uses a wedge. Which then makes a beginner more at ease with paddle speed. But watch a good foiler bounce his board as he paddles to catch a wave. Others just paddle in a straight line.
I think as one gets better it is due to style & technique improving.
From what I have seen in Piros Fiji foil video is the board flying horizontal to water surface with no wedge used I think. So that would mean best performance whilst flying.
There are numerous variables from body positioning, power paddling, wave types, current, surface chop & weather & wind.
At the moment I am using a 4mm wedge on my 6ft 8" JP board & feels great when up & flying at good speed with Medium NPryde wing shoulder high pushy waves. But would rather have a 6 or 8mm wedge for paddling back out to the break.

Oh. Just met a guy in the surf from DC boards. All the way down here, south of Wollongong from Currumbin Qld. I think his name was Dale Chapman. He was on one of his 6ft 6" foil boards. And he was ripping compared to me. On the foil he was turning just as easy as a normal shortboard & pumping back out to the break to start again.
He had the same hop & paddle, bouncing the board to catch the wave early. He had style & technique. So I then thought, this guy would do down wind foiling so easy. But to my surprise he mentioned it was the hardest to do. And he said it with emotion.
So what does that tell us beginners & plain surf foilers?

DC's a legend, love the way he throws that foil board around, he goes alright for a young fella hey.

Hi,

Just to show how the 10,5 mm wedge looks on the JP Board.

I went out late today in some small slow moving swell/bumps, sitting on the outside trying to catch them. On my first few try I was over the moon when I got on them, 3 out of 4

I also had the mast further forward than I ever had and thanks JB for help on that. Will try to play with the placement of the mast regarding to conditions.

The designers and developers have tested and worked this angle of mast VS / Board out. But I think it has been done only with Pro riders that can pop the board up in any conditions. Not struggling beginners like me.
The board is super stable, I have now had plenty of paddling time and less of flying...

One day I can remove the wedge.
It might be like training wheels for kids bikes





I have marked out were the handle is. Looks pretty central and neutral to a amateur like me

Cheers

Anders

Yes. He has inspired me to get turning more. I have just started pumping when I come off good waves with a bit of speed. Long way to go yet. But love the challenges.

Good stuff anders884. Basically my other foil converted paddleboard is set up with mast at pretty close to 90 degrees and seems to catch & ride waves ok and paddles easier than without a foil due to its excessive nose rocker.
So with that wedge you have produced maximum lift. But not sure on your paddle speed.
If it works for you & you are getting more flying time then good.
Where I think it may change on the JP board is on bigger waves more speed. But then I would be putting the foil back towards the tail near the back kick with the same wedge.
Would be good if you get another two wedges at about 8mm & 4mm and try those in similar conditions.
Going by your experience it looks like I will be making another wedge about 8mm for those more weak wave days.
But tomorrow for me the surfs picking up & I will need to go to a more powerful break to try the 4mm wedge again. If I can stop falling off my board. Haaa!

Another easy way to setup the base plate shim is to work out where you stand just paddling the board around. Not nose down not nose up. That point on the board where your feet are is the centre of balance of your buoyancy. This is more or less parallel to the entire ocean.
Use a spirit level on your phone to get this level where your feet are and set the mast up to 90 degrees to this. Pretty much works out exactly as you have done with your right angle thing but easier.
