Just wanted to let you know that I finally saw a pod of HUBs, live and in person, and although nobody was getting killed, it was possibly the funniest SCUBA-related activity I've seen in a very long time. It was on St. Thomas or St. MAarten (don't rememebr which).
The dive (HUB?) op had a bunch of hubs, and had tied a dive float to each one (the big innertube floats, not the little beachball things) on a few feet of rope, and I believe weighted the botton, since they all seemed to be vertical at all times.
Anyway, it was a hoot to watch. It was like "Underwater Bumper Cars" with all these people riding their HUBs around each other. Although I thought I'd never say this, I think it looked pretty safe, since the MOD was about 6 feet, and they always stayed vertical.
The float was a great idea, since I did the displacement calculations once and found that it would take way over 300 pounds to sink a full-size innertube.
Anyway, I though you folks would be interested, since I always assumed the HUB only existed as a PhotoShop image.
