... But you know I disagree that "Diving is swimming". Years ago I was on HS swim team...
I always figured that propelling yourself through open water qualified as swimming. Using the dog paddle, treading water (swimming up), or using fins all qualify. I agree that divers don’t need to swim at competitive levels, but do need endurance in order to be confident — especially when equipment malfunctions or currents make getting back to the beach more than they have air for.

I do believe divers need to be able to swim, but let's be accurate.The RSTC standards call for a 200 yard swim with no equipment or a 300 yard swim with mask, fins, and snorkel. Some instructors never do the 300 yard swim with gear. Others always do the 300 yard swim with gear because it is a teaching exercise, an opportunity for divers unused to snorkels to get used to them, an opportunity to work on kicking technique...
As mentioned, I see a significant downside to the swim with equipment, but have also spoken with divers that never took any swim test at all. They happened to have PADI cards but the blame is with the dive shop and instructors more than the agency.
