A vessel (boat, ship, even a person) floats higher in salt water since salt water is denser then fresh water.

It's the relationship between the density (displacement) of the object floating and medium that it's floating in. A boat will displace less sea water than fresh water therefore it will float a little higher. For the same reason, it's easier for you to float in salt water than it is in fresh water.
The Dead Sea has a very high saline content making it even denser. If you swim there it's almost impossible to sink.
An 8lb. bowling ball is the same size as a 16lb. ball but is less dense. An 8lb. bowling ball will float in salt water, a 16lb. bowling ball will sink!

The hull of a boat displaces water causing the water to push back on the boat with an equal and opposite force to the weight of the boat bearing down upon it. This happens regardless of the type of water.

Yes.
It floats higher in salt water, that's all.
Assuming the boat is seaworthy of course.

Yep they do float in both. The difference to a boat is negligible. Only that saltwater corrodes things on a vessel much faster in saltwater vs fresh water.
