I can freestyle and backstroke adequately... never could figure out the proper kick for breaststroke or butterfly, however.
As for sinking... [removed by CC] but for some reason my legs always sink.
Don't know what freestyle is, so no comment on that, however, I can crawl a bit, and breaststroke a bit less, the backstroke a bit better, no butterfly tho.
Absolutely no floating for me, and especially not my legs. So, in order to stay afloat completely, I have to start flapping my legs.

But, when I flap my legs, I get tired, so, naturally, I can't stay afloat for long.
