Yeah cool video Gashed , picked it up real fast.Teatree it's actually easier to catch waves on a prone foil compared to A Sup foil. Same goes for Downwinding , I don't think you will extra long boards with foils it's already proven it doesn't work . Maybe some redefined 8-6's just for Downwind on extra larger foils IMHO

How wide is ur board TT? My train of thought for foil down wind is something narrow like the width of a race board 25/27 wide also something with volume like a race board that glides better than a surf style sup . Just not to long.

Would something 14 foot be to long run nose into back of front swell as one on foil would be moving pretty quick ?






Yeah your probably right, have talked too jake about it he reckons it wouldn't work ,obviusley the glide on a wide 9,3 surf sup is not great. But remember our swells are not like Hawaii, my ideas would be to mount the foil a lot further forward than we seen when the guys where first riding the cut down 12,6 boards. As for hitting the swell in front, I do t think it would be a problem once the board is flying. My 14 is only 24 wide, very light and I reckon it would work for our conditions.Any way I'm going too try it, as I'm a mad experimenter ?





I have a real desire to try a miniature 8' starboard ace style board, I'm not sure exactly why though just feel like it should be done I just have to figure where on the priority it sits on my list of boards to build. I'm defiantly going to re visit my 10'6 x 24 and put a plate mount in it to try some of the new foils on it.




I have made a 7'6" x 26" race foil SUP (Cut a Maliko in half). it is much harder to stand on then I thought it would be. Kai DW foil board seems more on the money.

Ride safe,

JB


I have been building a few shapes similar to that the past few months and i still feel there is something out there that will be a lot better I'm just not sure what it is yet but I have a load more ideas to try.
















What's the theory behind the big bevel on the rails?
And the forward fin?
No criticism, just interested?
Unless it is Top Secret.

Yeah although the guys riding prone in downwind conditions on tiny boards, where towed in? I wouldn't like too be a couple k offshore and conditions change and have too paddle a 5 Ft board with a big foil attached in??

Jake has been Downwinders on his prone board.

Noz the bevel cushions a touchdown and gives the board more speed . Dave Kalama does it to all his boards.

G'day Piros , don't foil as of yet , tried once . You have the large size thrust , on your surf sup . Is this a choice for less speed needed to get up , or related to weight of the rider . On the board you showed ,the foil seems more forward than others , or just pic angle . Trying to gather all the experienced thoughts before I'm in balls and all . Thanks

at 72kg wet which foil would you recommend , plan to whack it on my old 7,4 jp

My mast is at 23" from tail looks more in the photo (iphone) I'm moving it back to 21". My recommendation with Naish Thrust is always start with the large , it's slower lift speed and very stable (heaps easier for learning) . When you start chucking buckets and riding bigger waves go the medium. It's a misconception that if you are too light you wont keep the foil down , just move forward on the board. The large Thrust is only about 10% bigger than a Kai GoFoil and kids ride that foil , plus you will struggle to downwind on the medium.

Re you board good pic I'd probably shift the mast back to 19" on that board , better to ask JB on this one.

I've just dropped my board at the local shaper to have 2 x 10" strong boxes fitted. It's an 8ft surfboard warehouse Vex pro which has quite a bit of tail rocker. Mounting the foil at the natural angle of the board would mean the foil is pointing slightly down. I can only assume this would result in the nose of the board lifting up once flying? Is this the case?

Should I get the shaper to compensate for this by installing the boxes at an angle more parallel to the deck? Or are the foils made with this in mind and to follow the natural angle of the tail rocker?

This is to be avoided at all costs, otherwise the foil will plough into the water when paddling, acting as a huge floating anchor. Once flying, it is not an issue.

Normally foils have some angle built-in to compensate for this, the simplest solution is just to move the mast forward enough so that the wing is flat or slightly pointing upwards when the board is being paddled. Otherwise the shaper will have to find a solution to angle a bit the boxes. Or you could use washers, or a slanted plate under your foil plate...

Does anyone know if there is much difference in performance of the 2017 Malolo foil and the new 2018 Thrust M foil . ??

Hi SUPG,
The 2017 Malolo came with a 70cm mast and 2018 Thrust medium and large surf comes standard with a 55cm mast. All masts being interchangeable depending on how high you want to fly
The only other difference is rear wing adjustment on the Thrust and not the Malolo, this allows the rider to adjust/ trim rear foil to suit different conditions.

I think Naish are on a really good thing with the interchangeble parts. (i have a go foil)
I would like to try my foil windsurfing as well as using for surfing and downwind sup.
Be good if go foil offered more interchangable parts for different foil sports rather than having to buy another complete foil just to go windsurfing.........
I have parked the windsurfing idea at the moment.

im sorry did you say $5101
Yes naish good idea being interchangable, but i struggle to see why these things are so expensive. Once design is down surely its a simple production? Next year hopefully they be couple hundred bucks as would love to try.

Because its like drugs and medicines. We all know that tablets are less than a cent to make, except the first one. The first one costs millions and millions of dollars.

The large price comes from the R&D before production.

Companies that keep prices inflated without innovation will fail. Right now, while its new the price remains high.

Yes, expect a spectacular drop in price (more than 3 times) for the entry-level foils (non full carbon) next year, as the recent announces show. Well-built light full carbon foils are going to stay expensive however. Quality carbon fiber and workmanship expertise is not cheap.

Hi everyone
I'd just like to question the durable claim for the thrust foil. I've had 7 sessions on my new large thrust surf foil and the rear wing now has a lot of give/ flex in it. Has anyone else had this problem?
Have only touched the bottom (flat sand) while walking out to deeper water.
The retailer says its probably cracked and i have to buy a new rear wing after only 7 sessions ...
Any thoughts, suggestions?
The rear wing is not bolted on through the wing like many foils I've seen, but has vertical section which slots into the fuselage.
Has anyone had the same issue ie is it a design flaw or am i treating a "durable" product too harshly by bumping it on a sand bottom occasionally when dragging it out to deeper water?

If this is the case, the cracks may actually be in the fuselage itself, in the slot box bottom or sides.

Try to disassemble the rear wing and look for cracks in the fuselage itself.

Then ask if this is covered by warranty. It should, and that's why I advise people to choose big foil brands that can change parts easily when things break.

The efforts on a SUP foil are huge, more in the whitewater than just bumping the bottom while walking besides the foil. But you should try to walk your board upside down, gently bumping the sand is nothing, but gently bumping the sand while some hidden water movement exert pressure on the gear may get ugly quick.

Foil gear will break or bend, these are still pionneer times. Especially with the new huge wings coming out, people should not expect the gear to be as reliable as a standard SUPing gear.

I personally think the foil used on the bigger boards where mounted too far back, I reckon mounted much further forward would work better on a longer board. Question is would the extra paddle speed of a longer board be sufficient too get the foil working in our more moderate conditions?


You are of course right, the foils should be more centered on long boards... but...

I guess people realized paddling speed is not really relevant for taking off on a foil, so long boards are not used anymore. The weight and bulk of a board is a huge disadvantage to perform the micro-pumping that is so important for liftoff. What is more important is the lift of the foil, this is why you see these huge wings appearing now for downwinding.

You can take off with a longer board by using its paddling speed, but once airborne, you still need a high lift foil to keep airborne in moderate conditions. And if you have a high lift foil,... you do not need a long board once your have got the technique.

Just FYI, I have recently tried a 5mm wedge on a Naish Hover 120, and it does not add any advantage, the Hover boards and Thrust Foils straight out of the box provide the best trim and riding settings.

that's interesting you would hope a dedicated production board would be set up perfectly, 5mm could have been to much though it all depends on the rocker of the board were the foil is mounted, I have been experimenting with a huge number of different setups recently and within a 3mm difference you can go from massively front foot weighted to massively on the back foot im starting now to go in .5mm increments to really fine tune things even further

Yeah agree with JB on this one , I only pack my Naish Thrust & other plate mount foils because I have a custom board with tail rocker. If you buy a specific foil board which is flat at the boxes you don't need to pack it . A foil laying back drags like a shovel paddling . However packing a flat foil forward doesn't seem to be a disadvantage paddling but you still get no real gain. I hear what you are saying Charlie but the mast at 90 degrees to the deck will get the board dead flat a flight , if you tilt the mast forward you will have to ride the board nose down to keep the foil flat. Just like if its tilted back you have to ride it nose up.

This pic is a good example of the foil flat on the surface and the mast at 90 degrees to the deck , this is almost an over foil but I held it by pushing the knees forward. I wouldn't have saved this if I had to ride the board nose up or nose down. I'm using your 5mm packing plate on this one Charlie

yes I would agree it all depends on the boards design( I have never personally seen the thrust board so cant comment and I don't believe I ever said it was wrong but I would not say if its perfect for one person it will be perfect for another) generally like you say you want the fuz parallel to the deck ( weather the mast is also depends on the design of the foil and if the mast is 90 to the mount and the fuz, it does also assume that the wings neutral center line of the front wing is running parallel to the fuz ( you would assume most designs would do this but its not hard to measure if you want to) so there are many variables ( talking in general about foil design)

Its just a balance of getting everything running just right so your not creating drag and you have the foot pressure nice and even between your feet, but even things like a un even leg length which is quite common may lend its self to needing micro adjustments. basically what im saying is people should experiment in very small increments as 1 or 2 mm can make huge differences and make life so much easier, you may end up back were you started but until you try you wont know!

Adjusting the rear wing on the Naish Thrust will give you all the advantage you feel you require for more/earlier lift. I have been riding with about 2-3mm of angle up on my rear and am riding literally nothing and catching ocean swells even without wind.



The Naish Hover 120 has a little rocker, which is why I tried it, but now feel (as you would imagine) Naish have this well balanced out of the box.

Ride safe,

Charlie,

Happy to try some smaller increments for the sake of trying. I have been experimenting with lots of configurations and settings and am always interested in understanding more about my foil setup. I'll PM you.

The wedge doesn't actually change your foot pressure once your up (this should be controlled by your stabilizer angle in relation to your stance), just your board angle and riding comfort. It only affects your take-off. I have found all foilboard at a certain volume/widge/size kind of stall up a little at take off. Whilst this is minimal, it was not lessened by adding a 5mm wedge. During the take off, yes the board lifted early, but it also does if I add more back wing, I do not think I actually caught swells that I could previously, and in fact feel I had more pumping power without it.

But, as I said, would like to try a few smaller increments to be sure. Will PM you.

Ride safe,

JB
