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?

you are correct, the keel will help the sailboat to center itself.

Caveat wind issues, raising a balloon would work. But still you would need a big enough balloon to hold 70m of coax up and the antenna. On the plus side you could slowly electrolysize water with the solar panels to fill your balloon with hydrogen :-). So you would only need to carry spare envelopes rather than a bunch of helium tanks.

If high endurance air drones are advanced enough, you can coordinate sea and air nodes to make a mesh that avoids clouds and line of sight all-together so you don't have to string the network over the sea level horizon. Maybe have autonomous platforms that allow both to refuel too if they use hybrid systems.

If you are at a high enough altitude clouds would never get in the way so solar power works much better.

Earlier quoted context omitted.

There is a system of AIS to broadcast position, course and speed of marine vessels. Perhaps one could combine this with a mesh relay network to forward packets to boats in the direction of land. An AIS and long range WiFi-like system running on top of sailor’s masts would be a fun community to bring together. Software defined radios could come in handy to handle multiple frequencies and protocols. https://www.marinet…

something like http://aprs.org

If you care about speed aprs isn't your boat. 1200bps in almost all cases, zero FEC, bandwidth rapidly disappears depending on how many digipeaters overlap.

It's good for brief beacon based things but most of the RF tech around it is still stuck in the 80s.

"Revolutionize fishing" seems to mean selling data to fisheries so they can pull even more fish out of the ocean.

Yeah this was my first thought as well. :( Like we need more effective methods of raping the oceans. Hopefully the scientific research will cover the potential drawbacks.

One upshot of better tech is significantly less bycatch, at least in regions where per-species quotas are strictly enforced. I'm told the latest sonars can distinguish both the species and age of fish in a shoal.

Younger researchers no longer want to spend that much time at sea, cut off from most of the internet. “It’s really hard to get the younger generation excited about going to sea,” says NOAA’s Meinig. “People think it’s romantic and then find they can’t text their friends and don’t have access to hundreds of channels of TV. It’s just a different style of life.” Fascinating. I guess the Saildrone is the ideal solution.

I wonder if this is really a generational thing vs a different type of person winning NOAA grants than in the past. Ie, people more interested in hype, advocacy, networking, etc than science.

Have an upvote, because I think you're bang on target.

Totally off topic aside: I’m seeing a lot of Bloomberg links these days and I’m constantly “over the free limit.” Sometimes the “web” strategy works, and sometimes it doesn’t (like this article for me). If I add up all the sources that are typical for HN it’s quite a lot. Bloomberg alone is $40/Mo now long term, plus nytimes, Washington Post, economist, FT, etc. I already pay for two of these — I don’t feel the need…

That's a good idea, but in the meantime: http://archive.is/DoZFv

Minus a couple of years, that is already a thing. Not sail drones though, as far as I know.

I know about drones smuggling small time packages in prisons and such. I was talking about a drone shipping tonns of drugs from South America to USA or Europe.

Yes, that was what I meant too.
