MikeFerrara:They do it in places around the US too where they claim that live boating isn't practical due to being in shiping lanes or whatever. Still long hangs in heavy current are no fun (especially if it's cold) and being "blown off" the wreck or line is a real possibility. We call them flag dives because that's what we feel like while holding on trying not to get blown away.
The boat I've been diving from is 45 metres long and it really isn't practical for picking up divers. It does have a zodiac as a tender, which is really necessary, but you couldn't free float in deco here either way. you'd either get run over or surface 5km from the divesite. It does mean you need to be damned sure where the upline is.... The nice part about this boat is that it draws exactly 5 metres in the middle of the keel and there are some points where you can attach a jon-line.
This year we're trying a different boat that's quite a bit smaller. I hope that goes ok.
