Clearest water you'll ever see, and the mining operations are still intact underneath with all the usual stuff, but also including a chapel and saloon. It was an underground city for about a hundred years now flooded under 50-100 feet if water. I took a tour couple weeks ago. Most of the scenes from the movie The Abyss were filmed there.
Looks interesting, although a cave/cavern dive where torches are not allowed is a little mind boggling. However, I've always had a preference for salty water over fresh water. (For instance, I like lobster, crab and scallops.)

This could work. I'm far too lazy to do it, though - Weymouth is around 3-4 hours' drive from mine so I don't go there every weekend. There's also some question around how to deal with the time delay of particles floating from Isel of Wight to Weymouth - it may be a slow process.
Vis measurement may be a little ad-hoc as well. The standard test is lowering a whilte disc until it can no longer be seen. This would get vis at the surface, but the amount of floating crap varies by depth. At the weekend, my unscientific observation was that the amount of floating crap was acceptable at 5-8m; but ridiculous at 30m.

That could work - are bits of mud from Southampton likely to be different to mud from Weymouth?
