Those are two very different things. The OP article talks about introducing air bubbles into the stream along the hull, the articles you linked talk about cavitation bubbles, i.e. water that vaporizes when the pressure locally drops. The latter collapse spectacularly and do indeed damage to surfaces. The former don't.
[edit: clarified which articles I mean]
- app4soft 6y ago> introducing air bubbles into the stream along the hull Placing air bubbles into the stream along the iron/steel hull in seawater... This is the worst idea as it would drastically increase oxidation.[0] [0] https://pubs.acs.org/doi/10.1021/es0109242 https://pubs.acs.org/doi/10.1021/es0109242

- bernulli 6y agoMost boats/ships already get wet with (sea)water, alternating with air at the water level. Hardly a new problem.
