I would also coat the plywood with oil based polyeurethane before
putting the flloring material on it. Then again, I'd do the same with
a roof.

Devil's Advocate checking in...

Define "cheap".

Determine the cost of replacing the entire floor with plywood,
finishing the plywood and caulking around the perimeter and compare it
to the value of the cabin itself. Is it worth it?

Consider the condition of the rest of the cabin. Are there other parts
of the cabin that are also poorly built and will need repairing in the
near future? If cost effective, it might make sense to include those
"uprades" as part of this project. If not, it might not make sense to
put extra money into upgrading the entire floor in an otherwise crappy
building.

Consider the construction method of the cabin. Are the exterior walls
built on top on the particle board subfloor and if so, what is the
condition of the particle board under the exterior walls? Will you be
replacing the interior floor section, while the integrity of the
building itself is in question because the floor under the walls is
rotten?

At the highest level, I agree with everyone else that a particle board
subfloor sucks and that it should all be replaced with plywood. On the
other hand, the cost of the new floor has to be weighed against the
value of the building (before and after) to see if it makes sense.

If I was worried about moisture, I'd go cement board. But if the OP
just replaced the particle board that was bad, and used sheet vinyl
instead of vinyl tiles, just making sure the edges were well glued, I
doubt he see any more problems.

The local radio commercials for Reeds Ferry Sheds:

Claim that unlike the Big Box sheds, their sheds don't use particle
board floors, because when particle board gets damp it becomes........

>From your description, it seems you do _not_ have subflooring,
but floor of particle-board. In this context, linoleum, carpet,
whatever
does not count as flooring.

3/4" of plywood/whatever for the only flooring would be kinda
cheap and bouncy. I'd go for nothing less than double-layer.
