The question is: can a solid float on gas? The answer is yes, as is explained pretty well here
But i was wondering if physical conditions (low gravity, very dense gas, pressure...) can exist where a real boat or any kind of boat (to use with a person or a similar weight) can float on a gas.
Supercritical fluids can act in a way similar to a liquid and similar to a gas, with no rigid phase boundary between them. But this occurs at high temperatures and high pressure.
But can a sea made of some high density gas mixture exist? In the sense that it has similarities with clouds (form, dispersion, etc) but in which we can float or at least use a boat to sail it?
