Hey, relax!
1. The incident I related happened 3 years ago.
2. Since then, I've gotten my AOW, several specialties, been diving 3 to 4 times a day whenever I could, and done a number of beach diving in Malibu, swimming against the swell in cold water, with a steel tank and 29 lbs on my belt. If I weren't a swimmer at all, I'd probably be staying home, watching TV, instead. Yet, I haven't read anywhere in Padi's stuff that you had to pass the lifeguard swimming test to become a diver.
3. As far as I understand it, Search and Rescue is a non-professional certification. It's not a credential to go out and save the world. It should make your diving better and safer, but it doesn't rise to the level of a DM or an Instructor where you are truly in charge of others.
4. One of the basic PADI principles for rec diving is to dive with a buddy who has a comparable level of experience, unless the buddy is a professional diver. The other basic principle is to dive within your own limits. As an example, if someone can't swim, it's probably not a good idea to go off shore diving, whether or not the ocean is rough.
5. I find it interesting that PADI has way less accidents than, say CMAS, yet does not require quite as much physically. Probably something to do with decompression diving being far more dangerous than not being a great swimmer.
6. When I posted my message, I was asking for others to relate their experience. Not for an expedited judgment on what I should do or not do. The latter I will reserve for my instructor who happens to be a Padi Course Director.
7. I don't think that calling board members idiots will make anyone improve their diving. Did you say you were an instructor?
