It might be an incident like that which leads Cozumel dive operators to require positive entries, so that divers do go to the surface and do not go under the boat and come up where they are least suspected.
On one of our dives a woman diver rolled in but rather than coming up to the surface and giving the "ok" signal or finning away from the boat.. she ended up going with the current and went under the boat.

Dumpster Diver:
You have the opportunity to change diving for the better right now. What I ask for you to do is pretend you are a dive operator in Cozumel. You are in a situation where the current changes and may be different from the water movement on the surface, meaning it may be necessary for the DM to enter the water to check it out first to make sure people are being dropped in the correct location. You have surface water movement. You need to drop 6 people off of a small boat so that they can get together quickly and descend as a group. They have a wide variety of abilities. Some are on their first dive trip. Some have 200 dives. You need to use a back roll entry.
What is your procedure? What do you tell the people to do?
Remember, if you propose something superior to what all the operators there are doing now, you will be doing a great service.
