So stoked on the whole Hydrocraft setup. The wings feel so smooth and confident! The Team at Hydrocraft are awesome to talk too and they went above and beyond to make sure i got my gear to be able to ride the next day! Happy to be supporting a business like this!!

Honestly, I'm blown away by the Helix. It's like the foil has ESP; it just does what I want it to do. It rides buttery smooth, pitch is dialed in, and it can do both huge carves and tight turns with ease. During my first session on the Helix, I became a better rider. I've only had 3 sessions on it, and it has helped me improve my waveriding skills immensely. Not only is it easy to use, but it makes my sessions incredibly more fun; I come in with wiggling eyes and a huge goofy grin on my face, telling everyone that I've had the best session of my life, because it's THAT good. Since the foil is so stable, I've also found that it makes foot switching easier, even when my feet are in the wrong place. And the whole kit is super light. The Helix is pure magic for me. It's also really nice supporting these local guys too; they're awesome.

WHAT?! HOW?!?! I was NOT expecting the 900 Helix to surf like that. Im usually on an 850 or 720 in waves over waist high so I can make turns, but then I rarely make a 2 for 1, or I’m so gassed if I do. I’m 160lbs on an 8’0 gator and was looking for a foil to level up my downwinding. What I got was the first ever for me pump out over 2 waves to the set wave, snappy heel side connection turn, then zip over to the steeper section, drop in, bottom turn, then some fun S carves higher up, cut back, back the other way, kick out as it’s walling up and easily pump out to the next one. I would say the 900 is just as easy to initiate the turns, and carves as hard as the 720 I used to ride, and I’ve never had a foil that easy to pump.

Amazing? Unreal is more like it. Rode the 665 today in marginal winging conditions as a test...and at 235 lbs in 18-20 mph, worked seamless. Great design and incredible in the surf. Can't wait to parawing this baby!

Mind blown this mast on the 775 dowinding has the glide and efficiency of a pure downwind rig while surfing and carving like a wave hound. Amazing maneuverability and slippery through the water while being rock solid stiff with the layup and side bolt connection system. Best of all worlds bravo.

Pre-Ordered the 775/140/80 kit and could not be happier. I've ridden it wing, tow and downwind.

Downwind this wing truly comes into it's own with good low end for the pop-up and fantastic top end. The handling and ability to carve at speed is only match by dedicated surf foils with nowhere near the glide and efficiency of this setup (CodeX, UNI Vyper).

Pumping is intuitive and low effort too.

In larger surf winging I was getting quite overpowered so I'm looking forward to a lower aspect surf wing to get released to round out the quiver. For small waves and downwind this wing does everything I can ask for amazingly!

I have ridden a handful of foils...in multiple disciplines on all types of equipment, and I can say I was sold the moment I got on the 900 Helix. It was the most natural feeling a foiler could have instantly. No figuring out, just easy, how it should be. It was forgiving, had incredible glide, had speed, and an impressive low end. The foil turns as hard as you want it to. Looking forward to what comes out in the future with this brand...and about to pull the trigger...

Been watching the development of the new Helix foil from Hydrocraft Systems and it’s clear this wasn’t thrown together overnight. The design language comes from years of testing, riding, and understanding what works — and what doesn’t — across multiple foil platforms and brands. No expense appears to have been spared in the level of engineering and refinement.
Matt, Brodie, Sam, and Henry are seasoned veterans in the foil and watersports industry whom I’ve worked with for the better part of a decade. While Hydrocraft may be a new company, the people behind it are anything but new to the game. These guys understand product development, rider feedback, customer relationships, and what it takes to build something legit.
The Helix is definitely worth keeping an eye on as it hits the market. Excited to see where they take it. Foil and Enjoy!!

First off, I apologize for the rave review I'm about to give but I truly had a magical time testing this foil in rather mediocre conditions. It took me very little time to start tapping into the potential. I was certain I would be under gunned in the 18mph wind but that was far from true. On my upwind reaches I could push the foil as hard as I wanted and it felt stable and smooth. Once on glide the foil came alive even more. I felt like I could glide easily to the next set without working to retain speed. The low end is remarkable and allows you to recover from most mistakes. Once on a set I felt like I could aggressively crank the foil into my turns and breach tips without exploding. I appreciated the winglet grip when I was on the edge of staying in control. From what I can tell, this foil has a huge range, is intuitive to ride, and it wants to rip as hard as you can push it. Small bumps have never felt so good.

All it takes is one wave to feel the difference. The efficiency is felt as soon as you kick out of a wave and start to pump. The foil naturally flies high on the mast and the subsequent energy gained is incredible. The 775 surfs incredibly well and is by far the best all around set up I've ridden. I'm sold!

This wing is nothing short of incredible. I am getting similar glide and pump-ability on the 775 helix as I was on previous wings that were in the 950-1000 range with a very similar aspect ratio. The pitch stability is excellent at all speeds and most impressive through hard turns and at the top end. The connection design of the tail, mast, and wing is superb.
I got to test my previous gear vs my complete hydrocraft setup in the same day with the same conditions and I was blown away.

I am really enjoying the helix 775 and 900. I was undersold something that has over delivered. A true surf inspired feel with all the pump and glide built in.

No complaints. Stiffness is all I could ask for. The finish is excellent along with the fitment into the fuse. The plate is nice and thin and the joint from plate to mast is nice and tight. Came from slotted bolt holes and its taken a few times to get a good dis-assembly and storage procedure down. Its easy enough to slide the mast out of the tracks with the bolts and tee nuts still assembled.

The first time I tried the 775 Helix, I came off the water saying, “That was the most fun I’ve ever had on a foil.” I bought it, and somehow every session since has gotten even better.

This foil has improved my riding and made the sport even more fun than I thought possible. It’s crazy how good it feels to dig into turns...it makes me feel cool, even though I know I’m probably not! I’ve gained so much confidence riding bigger bumps and in finding the fun in mini bumps.

It’s obvious the Hydrocraft guys know what’s up. You should probably buy this foil.

Excellent glide. Definitely connects the bumps effortlessly

Very smooth banking turns. Consistent power throughout the turn

Pumping seems very powerful and springy. Just a little bounce gives you a nice pop of energy

Super fun gear and a very happy customer

I love the 900 when parawinging on smaller bump days! I was really struggling to connect the dots, and this foil is a game-changer.

Wow! What amazing foils. I've had the 900 and 775 paired with the pivot 140 for a few weeks parawinging and winging in bay conditions and near shore ground swell surfing. The overwhelming feeling is easy pitch control, carvy turning, and great pump all across a huge speed range. The 900 does everything I want in mediocre to decent bay swell upwind-downwind laps. I can stand there, rip turns, or pump up-and-over basically on demand. It has made me laugh at the errors it's let me pump myself back out of. The 775 is a dream when the waves have some power. With the hand wing I can cruise around at slow speed looking for a good wave, jibe on a dime, accelerate like a rocket with the wing flagged out, and then have tons of glide to kick out and get the wing sorted for the next one. Yesterday I opted for self-tow-in with the parawing and was surprised to find I was regularly hitting 20 knots carving around on chest to head high unbroken waves and feeling comfy. Liveability wise, the system is great. It assembles fast and all the bolts and nuts stay attached to the mast and foils so all I need to remember to bring is the tool. No shimming required. The system just works. The covers are solid. There isn't much else to say except I'm a very happy customer.

Exactly what I was looking for! Surfy with plenty of glide. The helix 775 and 140 tail somehow stay under my feet and allow me to carve either direction at the last moment. I didn’t realize how much energy I was wasting trying to stay on top of my previous foil brand.

I demo'd the Helix 775+Pivot 140 in Hood, and ended up cancelling an order I had with a company infamous for its waitlist (y'all know who that is....) and pre-ordered this kit instead. Just showed up yesterday and immediately got out that same day during some mediocre conditions in the SF Bay and still had a blast. I'm coming off an Armstrong HA780 with performance mast and 50 cm fuse and this foil feels both more forgiving and higher performance. Fit, finish, and engineering are all superb and the Hydrocraft folks have come out with something that should be on everyone's radar. Now I just have to convince all my friends to switch over to this brand....

Can't wait to see what comes next from these folks!

This set up is out of the world. I have used it in big wind and swell at Hood but also really fickle, low wind in Tahoe. I am on the 775 and is super easy to get on foil in low wind but is also super stable in big wind and swell. I went from a 85cm mast to 80cm and have yet to breach. It intuitively brings you down when you get close to the top. It is also really easy to turn and the low end keeps you on foil between gusts. The whole system is also really precise. When I get back on my other foil it feels like the screws are loose. Amazing work R and D team! Mind blown!

I’m a mediocre downwind foiler. So I had to grow into the 775. But man is it awesome once you get get the hang of it. Amazing turn, glide, pump, speed range. Rode in 40 knot double overhead to 15-20 modest bumps. Smooth, zero drag, great lift, playful. Just a complete joy.

This is the Tuttle of love. Shocking how good this thing is.

Want to glide? Want to ride swell, turn with ease, pump twice and keep the momentum going? The Helix has got you. Easy to pop up and go, the Helix is user friendly, responsive, and fun.

I am not exaggerating when I say this foil absolutely made me a better foiler. I rode the 775 on a big day out at Rufus, and it was the first time I wasn't absolutely terrified in the big bumps out there. The foil felt so stable underfoot, but I was still able to turn on a dime. It was very pitch stable and easy to control that I rarely touched down (and when I did, my Hydrocraft ATV held it together perfectly). I felt like I could glide forever on this foil without sacrificing maneuverability. The low end was so incredible, and it allowed me to pump back up to speed like a pro. Honestly, it blew my mind! I couldn't wipe the grin off my face. Going upwind felt smooth and controlled in the gusty conditions, and felt just as good as down winding. As an intermediate foiler, this foil is the best thing I think I can use to level-up my ability and progress with the parawing. After using this foil for two days, I went out on my normal set up and I felt like I was stronger on foil than I have ever been. The progression was almost instant and I am looking forward to selling my foils and going all in with Hydrocraft!
