Aquatic propulsion speed record

[Pds314]

Your goal is simply to make the fastest boat you can that pushes off water, rather than air or with a thrust engine. You can build a waterwheel. You can make an underwater propeller. You can even swim like a fish or sea turtle.

Breaking Ground is not strictly required. But it is likely of enormous advantage.

I'm totally going to do this!

I may be wrong, but I had to ask. How many total challenges do you have to your name? Just curious.

I'm not sure. Some failed to take off. Some were pretty successful. Most were quite awhile ago.

Nice. Pics???

I tried this a couple of weeks back and it just span my craft around the waterwheel, so I'll give it another go!

Hey Pds314,

Sorry I don't see any entries to this challenge yet. If it's not necroposting, I have one for you:

Granted, 7.1 m/s isn't what you'd call a blistering pace, but I thought this was a decent first attempt.

Powerplant is two medium motors at 100% torque, although you quickly run out of battery running them.

The speed was quite unstable, even when the batteries were charged the craft was hovering around 6.5 m/s

Nice. Yeah it's definitely not a record. I did >18 m/s before Breaking Ground was even out. But I do like your boat.

[Pds314]

A light carrier powered by two large electric outboard motors. It is almost entirely empty and weighs just 301 tonnes including 4 tonnes of LFO.

Top speed is 24.5 m/s.


And an Aeris 3A can land on it with full fuel, with no use of thrust reverser, and then take off again.
