I thought they called it "Snuba", but it turns out I was wrong and it is actually "Hookah" (isn't that an Iranian bong-smoking bar??)
In any case, Snuba is basically a diver's oxygen tank that you tow behind you on a tiny inflatable, so you can dive with a long breathing "snorkel" without actually having to "wear" the tanks and assorted gear. It looks like this:

The cool thing about this is that one can dive "freely" and without the need for certification or specialised training. This is essentially snorkeling without the need to surface for air every 30 seconds...
I thought the club should buy one, which we can use for in-the-water boat maintentance and also for fun at the club cruises.
It turns out however, that Snuba is not a product, but some sort of licenced service. They are not for sale, only provided as a guided tour, in various exotic locales.. what a shame.. but a good idea for your next trip to Mexico, or Hawaii, nonetheless!
The alternative is something called Hookah (actually, the very nice folks at Snuba told me about it). Essentially, an electric air pump, attached to a breathing regulator at the end of a long hose, these Hookahs seem like even less maintenance - no tank to fill!

The unit is electric, it will run off your boat's battery. A standard 12V deep cycle shoudl provide at least an hour of diving. So you throw this baby in your cockpit, plug it into your "cigarette lighter" outlet and off you go to wet-sand that hull with 500-grit for tomorrow's race!
