A brand new giveaway starts today! This time, I am giving away a brand new Macfly paramotor powered by a Moster 185. We also just came out with three new designs and two new hats at Risky Biscuits Co. Every $5 spent on the webstore gets you one entry to win! - tuckergott.com/collections/new-arrivals
That was nice, a bit unbalanced, but you both did it. I wonder how" big bertha" and a big wing would act on water must be a more stable "boat", Maybe it would be the first Hydro Paramotor. Only take-off with the Wing staying dry would need paved pier......👍😊🇫🇷
theres a bunch of makers that use composites for things like boats, I wonder what a more custom designed "kayak" would do on the water, and how fast it would go, also you could add a couple pontoons for stability
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!
@@daniell1869 it would take quite a commitment to learn how to rodeo a whitewater kayak. They are specific about angles and weight shifts. I’m not a big fan of them or especially good at it. The roll and braces would have to be learned, it’s probably too big of a learning curve for his level of water sports interest… does that sound less pretentious?
@Wolvmarine yes, and he was going to give it away to someone until he did so and realized it wasn’t safe and he didn’t feel comfortable giving it away and getting someone killed. Yes, hypothetically it CAN fly, but it’s safer for everyone to make these kayak and mountain bike videos.
+1 for stand up paddle board. Might get 30-35mph out of it. Of course catching the nose in the side of a wake at 30mph could be sketchy. Probably best ridden by someone who can surf that is willing to stand on it. Would maximize the chance of the motor coming home dry.
v-shaped straight bottom with sharp end would plane. Round and curvy bottoms will suck themselves into water. It can be seen how they rise water from sides. A flat bottom can plane but not as well as V-shaped. Flat can be unstable
Your hull is the wrong shape. The straps going around the whole boat creates way more drag than you think. You also don’t have the proper angled optimally. Super cool vid though!
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!
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.
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.
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
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.
I thought the same thing. It would definitely have to go a lot faster to keep a wing overhead, much less, take off. Maybe with a flat bottom jon boat and a full sized paramotor?
You can get these small flotation tubes that are mounted on a frame that fastens to the kayak and they will be about 2 or 3 feet off each side of the kayak and they act somewhat like training wheels cause they keep you from turning over I have no idea what they are called but I can see that they are a must have in this situation They will take away all the worry and you can actually enjoy the ride while going faster
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
The back end sinks because it's not a planing hull. It's a displacement hull. The more power you put into it, the more water you have to push out of the way.
I think sticking a 2x4 under the front of the motor base to tip it back some would help. It's really stuffing the kayak down into the water at that angle. A bigger canoe or a sea kayak would be neat to see too!
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. 👍
I put a 24 pound thrust trolling motor on the back of a flat bottom aluminum canoe and I just mounted it about a foot from the very back and the battery out of my truck to run it and I was amazed at how much speed it had. I had two other friends in a Colman canoe and if they both paddled as fast as they could they still could go not even close to the speed I was going so I bet you were rolling across the water with the 5h/p motor I’d say 25 mph or faster
@user-yn1kx2mn9i 2 30lb motors got my canoe to almost 6mph, 1 30lb 4mph. Definitely wasn't planing. Skinny super light 14ft jonboat 14mph(planing perfectly) with a Yamaha 5hp that is couple more hp than that. It takes power to go fast on water
I had an"American Fiberlite" canoe back in the 70's we tied it on behind a jet-boat on Lake Cumberland in Kentucky and 10 feet became fiber-splat at about 60 knots !!! That was one of my worst days on the water !
Good fun, great effort. Displacement boat hulls speed is proportional to the wave length of the hull bow wave to stern wave, The longer the hull the faster the speed. On fishing boats you can put in 4 times the power to get a third extra speed, or add a third to you hull length use less fuel and have more workspace. Or as you mentioned flat hull to get up on the plane. Regardless you did it, congratulations 🍺😎👍
I think the drag was from the ratchet straps going under the kayak, you'd have to try to smoothen the bottom by tying it down from the top of the kayak, and it probably wouldn't sink as much, aside from the fact that you're also heavy in the rear.
Next evolution is a longer boat. Speed of “displacement” hulls like kayaks is limited by length. Longer the water line, the faster the speed. Cool vid.
As an avid ocean kayak guy, and custom sail-yak, I wholeheartedly approve of this. Just make sure you've got tags on your yak, otherwise fish and game will try to get you for "having a motorboat without proper tags and registration". Of course they gotta catch you first, and if you don't stop they can't catch you lol
They have these things called airboats down here in Florida, that actually use old aircraft engines. Next time you're down here you should check them out!
Thought Dan was going in the drink for sure!😂😂😂 Glad he was able to recover. I feel like with more power and a different vessel you may be onto some wacky new sport though.
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.
Back in the 1960’s there was a show called Flipper on TV. Fan driven boats were featured often, used to navigate the shallow Everglades. I think they were called air boats.
Love all your videos. Very entertaining. This one made me nervous. The instability was not worth the risk in my opinion. We don't want to lose you Tucker!
It went faster than you could paddle it, it didn't capsize, and the fact you had to fasten the motor to the kayak rather than yourself likely made operating it safer in case it did go over. So it seemed like a win for what it is.
So weird, I'm the opposite, put me in water, but you won't catch me in the sky. Large PVC tube pontoons may have helped the stability. Remove the prop, extend a shaft into the water and attach a water prop and you will be flying! Haha. In all seriousness, the hull is a displacement hull where the length of the hull will determine the max speed (theoretically). You either need a very long and narrow kayak, or a boat designed to plane.
That thing kicks. I have a trolling motor on my yak. Turns out there is all kinds of rocks and logs that my motor seems to have a almost magical way of finding. Not a problem for your little micro airboat. Don't show that to the Warden. Its considered to be a motorized watercraft. Needs tags.
Only the Lifetime Wave children’s kayak would have been a worse choice to try this. So many decent options available with just a little R&D. Still a fun watch. Thanks!
It's been a looong time since I watched your videos, I just couldn't get used to that old haircut. I now see you have a new haircut! AWESOME! I can watch your videos again!
Connect 2 of the kayaks to form a catamaran. Place the motor in the middle and yourself slightly in front of it. Make sure that you can change your seating position slightly forwards or backwards. This should solve the stability problem and the "sinking" of the stern at different speeds. You will certainly be much faster and safer on the water.
04:50 just look at that kayaks dont have a planing hull so as the center of gravity changes the water drag on the hull changes and increases, it look like the center of buoyancy is pushed backwards causing instability. normally as speed increases the boats bow lifts out of the water from the hydrodynamic lift but what we saw in the kayak is thrust is not enough to have that planing effect so the hull is not lifted out of the water so as the boat moves though the water drag is not decreased.
Need a longer Kayak so it has a longer waterline length which is important so that the back end doesn't settle in the displacement wake. Think Destroyer, long and thin and 37 knots. ;)
Add a set of steerable articulating outriggers for lateral stability and you’ll be in business! If you had a wakeboard strapped to your feet I feel like there’s some crazy new sport here. Like powered kite boarding or something to that effect. If you can figure out how to water takeoff, fly from one body of water to another and land back in the water you’ll be an absolute legend!🎉
The Cajun Navy is really upping the ante on their pond-skipper tech! Coming up next: The Cajun Navy pencils in future experiments with turbo-fan pond-skippers!
Paramotor is fixed at the base, but flexing forward at the top so the thrust is pushing downward. More thrust = more resistance to plane. If you can keep the thrust angle level and consistent, say with a strap or ridged support from the top of the prop surround to the back of the boat......you might have a chance.
This would be a great way to get around the quiet backwaters and harbours! it would really go well with the waterfront property owners and the quiet lovers! The biggest problem with trying to achieve speed on something like a kayak or canoe is the curved chine! The faster you go the deeper they run and the more drag is added, this is easily demonstrated by hanging a spoon under a tap the flowing water causes the concave surface to push the spoon away when convex attracts its similar to think of the top of an aero foil goes up as a kayak does the opposite at speed
the reason it digs down the rear end is because a kayak is a diplacement hull, its ment to move water aside, to reach its displacement speed without much force, but then it hits a wall in speed, if it would be a planing hull, im not sure you would have enough power, but it wouldnt dig as much in the back
Where should i start, all kayaks have a displacement hull, not going to plane out. you'd be better off with a paddle board, at least it has a flat bottom and you could strap the motor to the back with a seat probably mid way on the board that you could swim away from. I was wondering if you had a plan for getting out of the boat if you tipped. looked like you were strapped in...glad you survived
Looks like fun but most kayaks are displacement hulls, not planing hulls so it limits speed. Try it on a micro skiff for less plowing, better stability, more hydroplaning and can still be paddled too!
The kayak has a displacement hull design, like a ship, so with speed it will create a lot of turbulence and will tend to sink more in the water, reducing speed. The ideal is to look for a vessel with a planing hull, like a speedboat, then you will have speed without any problems.
The back end ' the stern', needs to be squared off. Like a boat or a seaplane float. The round shape creates a vacuum underneath that will not let it plane. Glenn Curtiss discovered this when he invented the flying boat.
Flying man is afraid of water! Too funny! I love your videos. I think this will be a lot safer than the bike trick! You should evaluate which one you think is safer, flying that motor, running it on a bike or "speed" boating.
That was frickin' amazing. Your own miniature swampboat. Maybe an aluminum flat bottom fishing boat (much like a swamboat would have) would be more stable and safer. But it wouldn't be as awesome. The matching red made it look.......almost factory-installed. Big thumbs up to you and your more reckless friend, taking to the max!
Awesome effort. Might be better with some trimming mass in the bow or less mass in the rear. Alternatively a boat with a planning hull and bigger waterline area.
Love the concept! But it will never go up to plane because the material in the kajak. It´s made of soft PPV or some other fat plastic, you need a shiny, hard surface to get it faster, the water sticks to the plastic. So, either fiberglass the bottom with slick paint on it, or get another boat..
That was fun to watch. +1 to all who suggested a planing hull. SUP, windsurfer, or surf board for sure would move out. Even a canoe would likely do ok as it’s long.
Pivoting hydrofoil blades that rotate down the faster you go. They have struts that lock vertical at max speed. The foils maintain a parallelogram profile flat to the water at all times.
so the back sinking thing is a boating phenomenon that happens right before you get the boat "on a plane". If you had a bit more horsepower you could push it up over that "hump" and you'd be planing over the water instead of pushing through the water. You'd be moving way faster due to the lower drag. Part of the issue is the kayak itself, kayak hulls aren't at all designed to plane properly. Sometimes you can overcome this by shifting the center of gravity of the whole boat forward, by leaning out and pushing down on the bow.
That is a displacement hull. You can keep adding horsepower and it will only make more noise and not go any faster. I don't know of any kayaks with a planning hull, even a whitewater kayak as someone else has stated is NOT a planning hull.
That’s the Lambertville Boat Launch… I wish I’d known. We are only 1:10 minutes from the there. We would have been you safety team. ( Dejay & Troy from Walleylife!) GOOD STUFF
The kayak is getting on plane it’s just that it is exceeding hull speed. It isn't great at that as it's designed for playing about below hull speed only, so its heavy for its planning area. Every planning that is heavy for its planning area has a significant transition phase where it drops the stern & lifts the bow high before reaching true planning speed. The transition phase has very high drag, but as speed increased into true planning, the hull levels off & the drag reduces again. The kayak behaves consistently with this. Light weight planning hulls with a large planning surface, such as high-performance sailing skiffs have almost no transition phase. This is a well-known behaviour in marine hull dynamics. Awsome thing to try, so glad you all survived.
Some pontoons , one to each side would add stability. Lot of kayakers add stabilizers like that, large foam fishing buoy attached with pvc pipe, or large pvc pipe capped off…. DIY. Not as loud as I would have though. Like a mini airboat, cool idea, needs a rudder, or stick control to direct the force for turning. How do airboats steer?
Also looked like the thrust angle was pushing the rear of the kayak down preventing it to plane. The 2ed drive when he leaned Forward it picked up more over the plaining wake
