as others have said the simple thing is just do a test. You know your area best and how far you may be. Maybe have a tow rope or such on you with the other end with someone on the dock. Jump out and swim/walk to shore and just see how it goes. Everyone is different and you may do well (rare but I've heard of cases) but only with a good test from a realistic distance can you know for sure. Enjoy a blanket and hot chocolate on shore and appreciate how much better you understand your situation and how to cope with it. Knowing for sure is a great feeling.
