Thanks for sharing that! It's great to see a technology like this actually out in the wild being put to use. How do these fare in the massive waves that happen in the far south? I was hoping there might be a video showing one righting itself but may I assume the ballast is just much, much heavier than the top?
Yes, we have a big lead weight in the keel. The southern ocean can occasionally have breaking waves over 50 feet tall!
