I'm sorry, but I don't see a disconnect. What I do see mainly comes down to:
a) Most agencies require a student to demonstrate swimming competitence before certification and another specifies that this isn't required;
DC -- Just want to make sure you are NOT referring to my agency, PADI, with the following comments:
PADI does require "swimming competence" prior to certification -- at least in my opinion which is perhaps "Clintonesque" in that "it depends on the definition of" swimming. I happen to believe that people who wear a Mask, Fins and Snorkel and propel themselves through the water are swimming -- just as people who propel themselves through the water on their back and waving their arms in circles are swimming, etc. You seem to have a different definition, but what is magic about YOUR definition -- self-propulsion through the water is self-propulsion, is it not?
Here is the disconnect to which I refer, the difference in the definition of "competence" as it applies to swimming, and how the language used may be read the wrong way by those who feel it is directed at them.
I am sure, for example, Peter Guy has no desire to put people in danger by allowing them a certification if they are not safe or competent in the water, and by saying that the agency he instructs for does not require competence means indirectly that Peter Guy does not require or care. I do not think you mean this, infact you stated as much, but that is how some of the posts do read.
Personally I do not define competence the same way PADI does either. From their
FAQ, one needs to swim 200 meters, or FMS for 300 meters, with no time limit. I am fine with the distance, if you cannot evaluate someone's ability in the water in that amount you have no buisness teaching water skills at all. However,PADI says as long as you can complete the distance, even if you are so out of shape or so poor a swimmer that it takes you 3 hours (no time limit) that leaves no room for the instructor to refuse to pass them.
Now, I am not an instructor, perhaps there are swimming evaluation standards that are not mentioned that would preclude someone from taking an excessive amount of time, but that is not what the information I have available to me says.
Most people who do not swim competively could still swim 200 meters in 6 minutes give or take. Someone who takes 20 or more IMO is a potential danger to themselves and their buddies in places where swimming may be needed, such as in current or tidal zones.
My niece at twelve years old swam her test in less than 10 minutes, 3 adults in her class took close to a 1/2 hour and were visibly fatigued when it was over. In fact one of them asked for a break before getting to work with the gear, and proceeded to exit the pool area for a smoke
. I would have failed them, but I doubt I would have been allowed to.
