Interesting.
The Boat Captain that I dive with (50+ Dives) has never mentioned an emergency recall proceedure. I will have to bring it up next time I'm on his boat and see what he has to say.
Helicopter is probably the best option.
Would be difficult to get another boat to cover the first boat though - if they are big enough to tend to divers and close enough to respond, then they are probably concerned about their own divers in the water, not someone elses.
The only dives we have on the West Coast of Florida are drift dives. You can't get a 'normal' dive until you get to the Keys or the West Coast. Instructors in our area train divers from the onset in drift diving (teach to the local conditions) so this isn't beyond the capabilities of the new divers.
In conclusion, I deeply appreciate all the comments I've gotten so far and sincerely look forward to other ideas. Loved the input about the helicopter though and the diver recall proceedures.
See - simply asking a question and soliciting responses from others on this board is very educational. Thank you all for your time and thoughts on this issue.
