AliExpress Paramotor VS Kayak

[greenman]

The hull design on that kayak is the limiting factor. You’d have to absorb a big learning curve but a whitewater style has planing bottom, and a sea kayak will have other advantages and drawbacks. The little lake tugboat is not the best option imo. Still, it shows it works!

I love that this motor seems to be useful for everything except its intended purpose.

Use your normal setup on a kayak, like a seaplane :D

This video is both awesome on its own, but is a great example for anyone learning about the performance of various hull shapes. That "sinking in the back" problem is something called "hull speed" which is basically the speed at which any given hull creates a bow wave that's exactly the same length as the hull. It means the hull is always trying to climb up out of a hole of its own making. Once you hit hull speed the amount of energy required to increase speed spikes exponentially. As other commenters have pointed out certain hull types (like those that can get up on a plane) work around the issue a bit, but it's amazing to watch it in action so clearly. Thanks!

Do it on a planing hull! A SUP or big windsurfer board with a seat and foot straps etc attached. That thing will absolutely rocket!

This is a great video for those who do not understand hull speed and a displacement hull. It was never really able to plain, which limited how fast it would go. Hull speed on that length boat is probably around 5 to 6 mph. You stretched that about as much as you could. You had ample power to go significantly faster, but the bow wave prevented it. Great demonstration of science.

Well, you've done it on land, in the air, and now the water (sea-ish). I guess that makes you an Ali Express SEAL. You already have the hair. 😁

Not bad for a small "play boat." These short, low volume boats are designed to play in rapids, to turn on a dime and be able to handle large waves with a very short frequency like you see on big white water rapids. They're designed for maneuverability not speed. A general rule for boat hulls is that the longer the water line, the faster it will go. Put that fan on a 16' sea kayak with larger volume and greater buoyancy and a slightly wider beam for better stability and you'd be on to something. Also, water is 75% more dense than air so unless you're putting a jet or rocket on there, you're not going to hit 50 MPH.

Tucker, I’m 42. I am beyond impressed with your articulable knowledge and the fact you have been this way ever since you started producing this content years ago. Stay safe young man, and never stop the adventures brother

You have had so much fun from this motor, no matter how much you pick faults with it, it keeps on giving lots of fun at low cost.

[mr.saddad]

You definitely need to try this on a 10 or 12 ft sit in or fishing kayak with the seat

[ErikNovikoff]

Your thrust line is off angled for the position of the paramotor. You can see as you hit the power, it wants to push the rear of the boat down into the water. Try putting the paramotor on a 10-15 degree upward thrust line (point the travel direction of the paramotor upwards). This should help put the boat on plane and give you more speed.

Nice! What I'd like to see is if y'all could strap a wing to it and get it flying. 👍

[beachtrash]

I have a couple of 15' sit on top Ocean Kayaks that would work great on! They are really stable, have a nice flat recessed area behind the seat for an ice chest that would probably mount in. The length would probably help prevent so much wheelie action.

[darthbiker]

I love how sketchy it is but also how fun it looks. Not a boating expert but I feel like your boat needs to be flat bottomed and long enough so that the engine can sit somewhere near the middle. But the important thing is Ali Express must be so proud of you lmao

[jamescline]

Two windsurfing boards with an arch between them for a seat and the motor, like a catamaran. Rudder pedals for steering.

[ThomasGrillo]

Wow! A single seat airboat! Very cool! Thanks for sharing this! :)

[Thebloxy]

Tucker is basically the AliExpress paramotor SEAL operator.

[caseyverser]

I could see a cool ground effect vehicle come from this.

As kids, my cousin and I put a 5 hp outboard on a canoe. We actually had to use big pieces of metal in the front of the canoe to balance out the weight. That thing flew across the water, this reminds me of those good times. 👍
