Steering is an issue though

[@richardjulien1329]

Suggestions : 1) trying to break the record with lego only parts. 2) trying the old exo force turbine : the blades are in both orientation, would be fun to see what happen with these. 3) testing the old propellers for technic planes ( there are different versions ) 4) trying with even more motors and propeller! Like 4 of them! 5) testing all the existing lego floating hull, from the very old ones to the most recent :D

[@vladidiazkutchov287]

Like a lot of people said, use a light gear ratio to trade some torque to some rpm. the 3 blades version is the most efficient (the 2 lacks surface and 5 constrain the water flow too much) so stick with it but try a bigger diameter or put 2 on the same axe (like 4 studs apart) to increase thrust. If you're not gonna use vanilla part then try toroidal propellers too. You can aslo use a rubberband as a pulley instead of a shaft to try to reduce drag under water.

[@gieljanlogchies8190]

Also a tip, if you have enough speed soon: You want a trim on your propellors so you can adjust the degrees. With this you can make your boat go above the water instead of thru the water. This will decrease the water resistance on the boat massively. It will be a challange to make that work with lego but I think if you have the knowlage you can do it.

[@123456lijo]

Both the hulls are fully immersed. If you could reduce the immersed section, drag could be reduced and major chunk of motor energy goes in overcoming drag. Try skipping the boat hulls like speed boat or make it lighter so that only a small section sinks.

[@ElFredo1998]

​@@LucasDynamics That will be the ultimate design challenge. I doubt it is possible using purely Lego parts but it might be possible using a Buwizz 3.0 as the power source. It could deliver enough power to archieve a power to weight ratio similar to pioneer era aircraft although there are many more factors to consider. Got a prototype yet?

[@Ghetto_Smosh]

To go faster you should probably have less drag in the water. Maybe move the centre of mass back as well. And different props. It depends on a lot of factors which props are most efficient, so do lots of testing as well.

[@LucasDynamics]

Thanks bro, really appreciate it!

[@reverse_engineered]

The GPS isn't very accurate: it has trouble measuring slow speeds because the resolution is on the order of a metre. You could get more accurate measurements by timing how long it takes to move between two fixed points. You could put some poles in the sand sticking up out of the water to denote start and finish lines. If you want to measure top speed, just taking a running start so that you are up to full speed by the time you reach the starting point. This is how water races are historically done: buoys denote the start and end and the outline of the course.

[@basicdriverlicense]

Adjust the gear ratio for more speed than torque. Maybe it takes time for it to hit top speed but it helps getting faster atleast, I hope.

[@LucasDynamics]

I will try this on the next one!

[@bunherr8974]

The key to fast and efficient boats is finding the perfect length of the hull, this has to do with the wave length along side the boat, it affects the drag.

I think you should upgrade the propeller. Your videos are amazing

[@jankokert653]

Great video! Suggestion: Make the propellers lager in diameter (approx 80mm). The motors have enough torgue. And you will get less water disturbance. Cheers.

[@LucasDynamics]

That's exactly what I planned for the next version!

[@pascalbruyere7108]

Hulls in displacement mode (versus planing mode) have a max theoretical speed. I don’t think you’ll ever go in planing mode, so you can calculate your max speed. Increase the length of your hull. Use one hull instead of two but for balance you might need two. Balance your hull so its flat when under power.

[@z3r0c00l2]

But the technology used is amazing Lucas. 👍👍👍👍👍👍

[@LucasDynamics]

Thanks mate!

[@GERntleMAN]

You designed nice looking but inefficient propellers. They are used at very high rotational speeds since their profilenose eases into the water instead of having a rather broad line cutting into it at the same time. So you probably need three to five times the speed, to get the most out of your design. The size is really not the problem, they are well sized. But you might be limited by the maximum pressure and torque they can withstand. Also the pitch is not necessarily ideal at 0° in the water. It depends on how deep your propellers are submerged and how the weight is distributed along your boat i.e. the point of gravity.

[@LucasDynamics]

[@MrBlubaduki]

Hey if you could change the hull shape it would help. At the moment your pontoons are trying to lift your boat to the surface but you dont have the power to do it so creating something that comes to a sharp edge at the front and has a flat bottom will be more efficient.

[@LucasDynamics]

Yes, not directly, but in a half year, probably...

[@janicecheah-tq5kb]

First one to do what you first want to do is use lighter materials second of all use lighter motors, but still stronger ones. If you want the stronger motors then put in more Lego floating items as it will balance the buoyancy, making it lighter and glide next put a spoiler at the back it will help toblind it across as it makes it easier. Add at least four motors two for each side if you really want a nice glide, put a triangle shape in front, directing all of the waters to towards the sides, allowing it to glide forward, and remember to put some floats on the bottom in between those two.

[@anthoaprizal2770]

The blades should be wider to get more thrust.

[@albertom82a1]

Propellers should rotate in opposite directions: one clockwise and the other counterclockwise

[@LucasDynamics]

True!

[@LucasDynamics]

My own ones turned opposite of each other

I reckon using larger propellers would make it faster. Since those motors you are using produce a lot of torque, you could put the gear ratio up or use larger props for maximum efficiency :)

It would be interesting to try, but I suspect it won't matter much. The torque required to turn the propellers will be much larger than the torque caused by friction.

[@LucasDynamics]

Thanks man, coming for you!

[@frasersteen]

Get 2 more hulls and make the boat longer, in displacement mode like this you should gain sqrt(2) x more speed. Hull speed is ~1.34 x sqrt(length at the waterline) The longer the hull the faster you go. If you can make the length:width ratio >8:1 you can start to exceed this. TL;DR - make it longer.
