Actually, the reason why you can float easier on salt water than fresh water is the salt. Because salt water is heavier and denser than fresh water, many things can float much easier than normal.
Or to put it bluntly, look up images of folk floating in the Dead Sea, one of the saltiest bodies of water out there. They float much higher in the water than normal beach goers in the rest of the world.

I actually heard once that, due to the nature of the Dead Sea and its ever-increasing salinity/density, eventually, it might be possible to not merely float but perhaps even walk on it.

it happened before. almost 2000 years ago.

is
cute. very charming

I'm sure she could, but it would be very wasteful of energy. I was once challenged to demonstrate that I could swim 50m wearing a 4.5kg diver's weight-belt without a wet-suit or any other buoyancy/swimming aid. The weight was easily sufficient to allow me to stand on the bottom of the fresh-water swimming pool; flat-footed, completely submerged, with full lungs. I had no difficulty passing the test, but I had to work much harder than normal to stay close enough to the surface to breathe. With sufficient power, I'm sure Momo could swim, but the battery drain would be much greater than just walking along the bottom.

So you can overcome something close to a ten per cent addition to your body density? I am a bit surprised, because I thought that the game in swimming is about smaller margins. May be I shouldn't have? After all, scuba divers wearing a weight belt are not reeled back to the surface. Ok, I know next to nothing about that, but already Captain Nemo explained that moving underwater, in particular changing your depth, is more about steering as opposed to dramatically changing your net buoyancy.
Anyway, apparently Momo's density is a bit higher than that, even though she is unlikely to be loaded with metal gear.

That old lady ass seems to be in remarkably good shape. Most at her age are about 6-8 inches below that. :-o
