My pet peeve was always how many OW students don't have any previous "water" experience, and that the 200 yd/mtr. swim test was a puzzle to me as to what it was there to prove. I'd like to see some kind of tests that would insure that someone is actually very comfortable in water before entering the OW course. Knowing a proper swim stroke (maybe just doing ONE lap to show that). Some testing that would show that the student is not at all "afraid" of the water, of putting one's head under it, etc. I read of someone saying that they had a student who signed up for OW to overcome her FEAR OF THE WATER. For me, that is not an acceptable reason for taking SCUBA. I beat to death the Swim Test thing here years ago, but will say that when I assisted on courses, 80% of those doing the 200 Swim didn't have a proper stroke. Yes, swimming and scuba are distant(?) cousins and you don't have to be a good swimmer to be a good scuba diver, but I feel that anyone doing ANYTHING in or around water that is too deep to stand in should know how to properly swim.
