Saw the video yesterday on YouTube. I wonder what happens if they get into very strong winds or very strong swell - if they tip over, do they get up by themselves? What happens if they submerge?

Apparently they figured out how to do it, but my question is, how exactly are they doing it?

Isn't that what a keel does?

I work for a company that builds boats for many of the same goals in a more traditional form factor. The potential of autonomous marine vehicles is very high, and a very exciting field to be working in. https://www.asvglobal.com/

(If you're interested, we're hiring!)

Yes, but a keel is also limited right? It's still possible to tip over and - if potentially submerged, not come back up?

But to be honest, I have very little knowledge on this topic, so maybe a keel is all it needs!

The video said everything on it was 100% submersible and saltwater-proof, and then all you need is an air bubble in the "sail" and it will eventually float up with the right side up, no?

I've actually seen one of these at sea. Not this particular one but a similar autonomous vessel. Large swells aren't a problem. If it floats a swell will pass under it. Breaking swells are a concern and usually occur under gale force winds.

A boat has a displacement that is less than water. Which is how it floats. A small weighted bulb in the keel keeps everything pointing upright. You can mitigate the forces on a sail through 2 ways: heeling is when the entire boat leans to one side, heading up is pointing the wing sail into the wind.

Wingsails are pretty well understood and used extensively in racing. Volvo Ocean Racing (VOR) and America's Cup are 2 examples.
