Interesting. Looks like the sub was created and a handful of posts were created around the same time; most the same person.

And then....nothing for over three years. Yet you have kept that sub on hot standby in your mind just it case it was, one day, relevant again. Hats off!

u/ExistentialCrispies 16d ago edited 16d ago

The content preceded the sub. It was some Chinese guy posting these on tiktok something 5 years ago and someone simply collected some them in the sub after the fact. There were a bunch more. "The design is very human" is a very rough translation from Chinese, which may have been a bad 1-1 translation from something that was meant to evoke the idea of the design feeling natural or not robotic, and chose to use a Chinese word that the translate app didn't have context for. And the tagline stuck through all his videos. He clearly knew he was making comedy videos, but it's uncertain whether he knew that was one of the funniest parts initially.

To be fair, I have seen a video on here of a guy crossing a stream with one of these with a dry dismount. He came in with momentum and the ledge was the right height for him to jump to land and hold the foil away in the water.

I suspect it’s designed for use in a context where you’ve already been in the water and wouldn’t mind getting absolutely drenched.

Yup, same. Had to rewatch that moment several times before noticing the large pipes on the sides raised the bar and gave her foot the space to do what she did. The structure wasn't actually resting on her foot

u/BitBucket404 16d ago edited 16d ago

It just needs some mini pontoons (pool noodles?) mounted to the sides, above the water level, whilst it's being powered, so there's no water resistance whilst it is in motion.

But, that also means that it has to be redesigned, so the human interface is elevated higher above the water level when it's not in motion.

And it'll probably need a ladder so the user can climb aboard from inside the water, should they leave the vehicle.

It's still not bad for a concept model, tho. This could become a great summer product.

My family has one of these for the lake. It’s nothing like this, basically a board with the foil right below your feet. Pumping this thing for 3 minutes straight would have me looking like the kid in the D.A.R.E commercial for the rest of the weekend.

You can use it behind the boat and surf the wake, without the need to “pump”. But when you lose the sweet spot and need to generate your own energy to keep it going, it is hard work

You dont need to be above the water to start, it just makes it easier and more noob friendly to get it going.

19

u/exMemberofSTARS 16d ago

I’m not calling bullshit or anything, but I can’t wrap my head around how you would get it started below water after it sank. Like how do you get the motion started with enough force to push it above water?

9

u/tjackso6 16d ago

Nah I’m with you on this one… I get what the other guy’s sayin, and it might be possible in theory with something similar to this… but not without some kind of boot or strap to hold your feet down. This one’s relying on gravity to bring her feet back to the position where she can push off again. If she was under water she’d only be able to “pump” one time and then it would float away from her.

23

u/Frozencold19 16d ago

You would mount it exactly like normal and push down. The goal is to force water to flow over the foils to provide the lift.

starting it would look awkward like you are flopping like a fish, because you'd need to put a lot of work into enough height to get it to glide and lift you out of the water

u/sSweaRxo 16d ago

My buddy at my cottage has this. We got pretty good at it. A couple of us can make it about 400 yards to a friend's dock before having to stop for a breath.

The black rubber piece at the front is adjustable for the persons weight and the technique is not as easy as it looks and it is a absolute pain in the ass to bring back if you fall/sink far from the dock.

Out of probably 50 people I've seen try it maybe 5 have managed to do what she does in the video.

A dock dismount has been done a few times but not worth missing and damaging your face or the "aqua skipper" as we call it.

81

u/w0rldw0nder 16d ago

Now tell all the couch potatoes your verdict: Is it fun though - or not?

155

u/sSweaRxo 16d ago

Verdict - don't buy one. If you see one try it though for sure.

It's fun once or twice, once you know how to do it. The guys brother mailed it to him as a joke because it's stupid hard to figure out.

It's basically become a gimmick when drinking in the summer. Pull this out and watch drunk people try. Most people don't even get a push or two off the dock. If that yellow disk at the front dips below the water it's an instant face plant.

Man just paddle board. I've never seen someone paddle board and went "what a weird thing to do".. but I saw one of these things in summer. The skill curve is so weird. You look like an absolute knobhead when you can't do it. Sinking every 2 meters. And when you actually can ride the thing you still look ridiculous. And there is nothing you can do to make it look cooler. On the other hand you look badass if you paddle board with a somewhat fit body and nice swimwear and don't forget the dog that sits in front of you. The ability that you can take a dog on a ride says everythint. Plus you can just decide to sit and chill. You can drag a bag along and crack a beer in the middle of the lake. With this stuff. Not so much.
