Re: beathing apparatus for or bottom maintenaince
OP is a certified scuba diver but hasn't dived in a long while?
I was going to suggest just renting a tank and scuba gear, and forget the hookah stuff. That way you have a Buoyancy Compensator, ditchable weights in case of emergency, a compass just in case. You can be neutrally buoyant at whichever depth you're working.
I'm ignorant of hookahs, so maybe I'm missing something that's great about them. But I've cleaned a boat bottom in scuba gear, it worked out fine. And if perchance you drop something you need to retrieve, you can drop down and look for it.
And getting back into diving has advantages too, you're a mobile underwater creature, without a tether, and can enjoy the underwater world away from the marina silt and ablative paint clouds.
If OP has health problems which contradict diving, then I take back all I just said.
