As far as pool day for training, you don't actually have to touch the water. You just go in an inflatable raft. You can/may have to wear a life jacket in case you would fall in, but it's not a swimming day, it's a demonstration of the life raft.
I can swim but I know pilots who can't. I was just genuinely curious about it for someone who may be applying and in that situation and looking for the details. Thanks for all the answers everyone!
