So just for context.

Fixed wind turbines can only really be put in in 60m depth or less. Water that shallow is usually close the coast though there are some exceptions like the dogger bank, but that’s rare.

If you are 100m off the ground you can see 36 km out to sea. (Or be visible 36 km from shore).

The EEZ of countries, where you can install wind turbines, is 370km from shore. Currently (new tech) there seems to be floating offshore capable of operating at 1km deep waters.

If floating wind takes off. Visibility might not be an issue at all. Wind speeds are higher and more constant out out sea. It’s a win, win, win. If it can be made cheap enough.
