Im having a lot of trouble with the 5 minute prone float. Im an athletic guy that weighs about 200 lbs. with very little body fat, i dont know if that puts me at a disadavantage here or not. I can swim/tread water all day long, but when i go to float i sink- no matter how much air i get in my lungs. Im BDCP pilot heading to ocs soon are they real picky with the float? i can do it kind of if i kick a little here and there. Ive been practicing every day and its starting to worry me. How the hell do you learn to float?
