Foil SUP / Re: DIY foam wings - how to

They look great , Cloud 9 has just released a version along those lines but not quite as radical as yours. I've been test riding them super-efficient wings.

Those new wings look wicked, but the design and theory behind it are worlds apart i promise! Not saying mine will work better, just that at this point its very different and no one can know for sure until we have tried it

Close! This one isnt a flying wing but youre on the right track. The horten brothers were also on the right track, they just didnt realize it at the time.

Yeah im not sure what it is, its hard to tell right now with a long fuse and wrong tail wing. shes certainly not breaking any records for speed or manoeuverability however it does feel super nice, quite stiff until you lean it over and pull into a turn where itll just bite and go. It threw me off the first time i tried it in the surf as i wasnt ready for just how hard itll turn when you let it.

This video is a snippet from an 11 minute film. i was doing a roughly 4nm run, and in the 11 minutes i covered about 90% of the distance. That with a fkd water logged board and a wing thats still covered in blemishes and 40grit sandpaper scratches!

It looks like its pitch unstable but its the opposite. so rigid in pitch it requires such heavy foot work and large trim inputs, add in a 30kt wind chop on top of a swell and you can see why i need all of that 750mm mast!

Spot prize for anyone who can guess the theory behind this wing. Im not giving any details but i cant find any info relating to it previously being tried on a hydrofoil.

Trying out a 1 metre super gull. Didnt have access to my mast/fuse due to a nation wide lockdown so ive been trialing it on my mates axis standard axis fuse.

 Definitely feels too long for the gull and the curved tips on the tail wing also dont feel right, there may be some inteference due to turbulent water coming off the 'elbows' of the front wing which are about the same height, although a little further outboard, as the stab tips.

Besides that this has got to be my favourite wing so far, custom or production. Ive done 10nm of downwinders, 3 sessions ~waist high surf and 2 in shoulder- head high, for a fairly large wing its just awesome, the faster it goes the better it feels.

Now, if only i had a board that wasnt composed of 90% saltwater, 7% foam and glass, and 3% wax and cracks

Cheers jeg, Its 1180mm x 200 x maybe 30mm, not the smallest wing but pretty high aspect.
I have a maliko tail for this foil, chopped about 70mm off each tip. I havent really tried it surfing since the chop but downwinding it is faster and  alot looser to turn but also lost alot of pumping power. I would just buy a new tail wing if it were me

This is my second  session on the gull, still cant quite figure out the pumping cadence  it feels alot different to anything ive tried so far. Seems to really like short sharp pumps

And the (sort of) finished product. I made the fuselage a few months ago with an axis front wing mount for accurate comparisons.
The gull wing is super easy to flat water sup start, easier than the axis 102 and much easier than the axis 1000 high aspect to get going, fairly similar once up and pumping to the 1000, maybe a little bit slower owing to its size and leading edge shape but it turns like a wing half its size.
Few pics from my second dock start session on it. Ive got the tail wing at zero right now but ill try a few different angles later in the week when we get some onshore breeze for upwind/downwindera

Cheers surfcowboy, I cant wait. So tempting to throw it in the water before paint

Kiwi theres 2x  3 or 400g DB patches 200mm square + 2x 200g twill on the top, and the same on the bottom but with a layer of 300g unis on the 45* and a 100mm strip about 3/4 of the span. Feels pretty stiff

Shes coming along nicely now, got the bottom laminated -
 2x 300g DB patches over the mounting plate, 1 strip 300g unis spanning 3/4 of the wing, 1x 300g unis at 45 degrees and 2x 200g twill over the whole lot.

Once that was dry i dug out the leading edge and filled it with some individual strips of unis and then bog.

Next i filled in the trailing edge and wing tips where i had dug all the foam out before laminating to get carbon on carbon contact, now the fun part. Sand it all!

More sanding. Dug out the foam in the trailing edge and tips as these will be solid carbon. Did a 200mm square rebate in the centre for 2 layers of bi ax reinforcing over the mounting plate. Was thinking about a little trench running the full span to fill with unis to form a spar but im not sure if it will need it or not
