Yes, I am in SFBA; I know about Saildrone; Sailbuoy, Liquid Robotics and a few other similar companies pursuing small data-collection drone boats. I didn't hear about Sofar yet - thanks for the link.
As a full disclosure, the boat I launched was made under collaboration with Blue Trail Engineering ([1]) known for SeaCharger ([2]). All cool parts on the photo are from them; my parts were camera / extra satellite modem / some cloud autopilot. I am way less cool than Damon from Blue Trail Engineering.
As for my solar drone boats hobby, it's so slow moving that there's nothing to follow at the moment. If I get the second boat out of the CAD stage, I would probably get something on my low-profile youtube channel ([3]). But I would not expect anything too soon: bigger boat requires very careful engineering, and with my limited hobby budget it will take time.
Anyway, thank you for the words of encouragement. :)
