Weak Divers in Strong Currents
--------------------------------------------------------------------------------
What are the dangers of strong currents for inexperienced divers?

The title has a different answer than the body of the post.

We are all weak against even the slightest current. If we fight it, it will always win.

An inexperienced diver may well chose to fight the current.

An inexperienced diver might likely not recognize a vertical downwelling current.

An experienced diver? Experienced means that they have seen this situation before and therefor should be more likely to recogize it and know how to deal with it.
 
The side effects of working hard against a current can be more dangerous than the current itself.

Struggling against a current can lead to overexertion, exhaustion, out-of-breath feeling, my-reg-isn't-working-right feeling, and just generally increase stress and/or induce panic.

This both applies to a diver strugging against the current when underwater, and to the diver that surfaces downcurrent of the boat and has trouble getting back to the boat.

Death.

You get tired fighting the current, you panic, you drown.
Sometimes you take someone else with you, maybe a stranger trying to rescue you, maybe a loved one.
