I was one of a group of Just Stop Oil activists given the longest-ever UK sentences for peaceful motorway. Six months into my incarceration, this is what I have learned
Not directly related to climate change, but Just Stop Oil has been in the news a lot.
I’m pretty sure you’d need more than a hole saw to sink a megayacht*. The hole would need to be big enough to overwhelm the bilge pumps.

Side note: the definition of “yacht” includes basically any boat with a cabin for sleeping and cooking, and can be 10m or even smaller. A lot of people with “yachts” are far from millionaires, let alone billionaires, and in fact many of them are basically hobos living aboard as their only residence and doing the nautical equivalent of #vanlife (which IMO is a very “solarpunk” lifestyle, BTW). Whenever we’re talking in the context of sabotaging the billionaires, we really should be talking specifically about superyachts or megayachts. (This is also why we shouldn’t actually be rooting for the orcas, as they are almost exclusively attacking small yachts, which aren’t the correct target.)
I’d assume it depends on how many holes per battery charge and how many batteries you can carry.
I think it would also depend on the speed one could drill holes with an underwater drill, as opposed to cutting them with some other tool (like an underwater sawzall, if such a thing exists), or making them with another method entirely. After all, it’s not just an issue of battery life, it’s an issue of finishing quickly so as not to get caught or give the crew time to stop/repair the damage.
Maybe a battery powered hammer and a 6" nail? Probably a lot faster, though more holes would be needed.
Need more info to make this math happen…
