do you consider yourself a strong swimmer?

Yes. But not competitive or long distance or "rescue everyone from a shipwreck" style. I have a natural ability to float- so that would help. I once swam a mile for my lifesaving course- I never got to finish the course since I opted for rest time over training. I am definitely out of shape, so I'm sure I could easily overestimate my abilities or stamina. But, still, I think I'm a moderate to strong swimmer.
