I'll say this: I've done bottom jobs and ive seen a plenty of boat bottoms.
I actually would use a hand held wood planer( the electric spinning kind) on some boat bottoms and probably make it work 😂
Now the more reserved approach is this tool.unless your boats newer then I too would be more cautious.
But most of it I'd let her rip.but with that said if your curious how it'd do?they make the brushes in brassy,regular wire brush wire then stainless steel! But I'm betting it dulls them out to make you groan either way.
But I'd be hopeful it would flying out the collected gummy material it's going to try to get clogged with either way. to let you keep lopping away at it.give it a try and tell us all about it if your about to do your bottom. you can always return it.😂

Yes, blasting large amounts of highly toxic chemicals into the air that people breathe, and on the ground where it will poison everything living, is irresponsible. PLEASE do not do it!

If they caught you doing this on the grounds of the marina where I am at, you would be kicked out immediately. And I fully approve of that policy!

But gliding them through the water where 3/4 the life on earth breaths for them to slough off is fine?
I recognize a fall out progger...ha!
That's ok Francis you know we use parps to collect our scrapings and put them in the trash.did your dose of drama do you good? 😂😳

I don't know what a progger is, and even less a fall out progger. And my name is not Francis.

To answer your question, I would much prefer not having to use toxic chemicals that kill marine organisms. But it is the only practical way to protect the bottoms of ships from fouling. So using this in the water is pretty much unavoidable. But the least we can do is to minimize the harm we do with that, and that means using the least-harmful substances that do the job (no more TBT) and to contain the toxic material as best as we can when applying/removing it.

For this reason I believe it is standard in every responsible marina to require a vacuum attached to the sander.

Your rotating wirebrush does not generate 'scrapings' that you can collect with a tarp (I suppose that is what you mean by 'parp') but fine dust that you are spewing not only on the tarp under the boat but also into the lungs of people (and animals) around your work area.

Yes, it is as dramatic as it sounds. If you can't understand that and make fun of '[my] dose of drama' when I pointed that out you need to work on your education in various areas. I suppose you have heard of Don Casey? One sentence I remember from his Good Old Boat book is that the dust from sanding antifouling 'can turn you into a rutabaga.'

'Nuff said.
