I think you guys are missing the point. Drift diving with or without a buoy is very dangerous. Heck, leaving the other divers on a ball is dangerous when you are chasing the other divers. If you had a chase boat maybe this is an option but I don't see how you're going to drag the drifting divers back to the main boat? Having them drifting in a major shipping lane with or without a chase boat is very dangerous. It's much safer to have the divers use proper equipment and a strong enough up-line to tie off to the wreck and support the divers. Like I said before, if a container ship can run into a light tower siting up 150 feet, you think they are going to see and steer around a float ball, lift bag or little chase boat? Your best option is to stay close to the boat. Maybe the ship will see the dive boat or can be called on the radio. By the time an 800 foot container traveling at 18 knots saw a float ball it would be too late to turn the ship. I really don't think the container ships sit there and scan the water with binoculars miles in front of themselves looking for a float ball. They rely on their radar and if they are looking at it will steer to avoid a moored dive boat. A chase boat is a wonderful thing but I don't understand how you tow them back to the dive boat? If you were doing a drift dive and the boat was following all the float balls, this is a very different situation. I have done this and although I don't like it, it's very effective for this type of diving. I don't think it works well in a 2 knot current with a moored dive boat. Being dragged at 2 knots against a 2 knot current back to the dive boat is not my idea of an enjoyable deco hang.

Those on the main line should have already been checked for problems. If you could get these guys to coordinate, everyone could drift when the current is moving, and everyone could sit when it is not.
