I'm planning on getting my SCUBA cert a few weekends from now (weekend clases, dives the next weekend) and I'm a little nervous about the actual swimming aspect of it- I know that soudns stupid (we're going to be in the water, obviously there is going to be swimming required) I haven't actually swam any distance in several years- I can swim and am not going to drown or anything like that, but I'm still a little nervous. I'm not planning on doing any really vigorous diving- I will admit to being strictly a 'tourist' diver. Can anyone offer any advice or words of wisdom on what type of swimming is required? Thank you!
