Re: Keel Crab hull cleaning drone
I agree it would be useless on hard growth. In my case, I never get any hard growth on the bottom, only heavy slime. Keeping that to a minimum would be value, especially if I could do it on my own schedule several times per season. I'll answer Capta's question, in a reply to him, but remember divers aren't allowed here.
However, I didn't see anything in the videos that actually showed what was just cleaned, which does make me suspicious. Indeed, one would still need to dive their prop, strainers and thruster tunnels, but I find each of those pretty easy compared to wiping the entire bottom.
