Explorer Paddle Boat

[Sariel]

Just a test with a third method of water propulsion that came to my mind. Not sure what else is left: oars? Sails? Turtles?

Nice boat. whats the gear ratio?

[Bob De Quatre]

It seems really effective!

Why not do something like the picture below, that combine a paddle wheel with a rudder?

3:1, as shown in the video and at my website, too.

Interesting. I wonder how well these would work together.

i think, a real working sailboat would be very interesting. :)

The most effective approach to power a Lego boat IMHO. Thanks for your research.

Turtles!

Turtles!

All the way down!

I wonder how fast this would go with RC motors (and suitable shielding to prevent the splashing water from shorting them and the RC unit out).

[Paul B Technic]

This looks like a really good project.

As for what's next: a lake bed exploring ROV! You may be able to do it by flipping over the boat hulls and keeping everything in the bubble produced when the inverted hull is submerged. That's really dicey though, so I'm imagining a device encapsulated with a two-liter soda bottle that acts like a hamster in a wheel - by spinning the bottle around itself.

Hamster power!

Cool idea, Maybe build smaller paddles with more blades and possibly splash guards to prevent PF parts from getting wet.

I agree with tommy, more small paddles around the edge or a large wheel instead of the four blade design ... Means more consistent power delivery
