But what's a bigger risk:
Going for a little bit of a ride on the line while the boat drifts?
or a boat pulling loose from the wreck, while divers are in the water?
If the boat pulls loose, you're stuck with a bunch of divers doing drifting ascents (possibly at different depths, drifting at different speeds, etc.) Lots of potential for someone to get lost
. Or you can try hooking back in with divers on the wreck, also not a good idea.
On the other hand, that would have to be one hell of a windy day to give you a ride all the way to the surface. You have the weight of the anchor and the chain. Not to mention a properly weighted diver, at depth
, with with an empty wing is pretty negative. And a smart diver will dump at least some gas before pulling, more if conditions indicate that they're going for a ride.
LakeSuperior, what kind of depths could you possibly be hitting "close to the beach" that your dives require a "fair amount of deco."
Not trying to be a smart ass, but like I said before, that's the way most of the boats have been doing it around here for years. In case you're not familiar with the diving up here, there's 2 little wrecks called the U-869 and the Andrea Doria. Out there, even if a diver who's been out of the water, does a bounce dive, just to pull the hook, they'll need to hang for a good 10 minutes. And that's in 260 feet of water in a spot that tends to have ripping currents.
