Hi Cesar, another bouyancy formula question:
Bouyancy Force = - (density of fluid displaced) * (Volume of object submerged) * gravity
The density if sea water is higher than the density of fresh water, so the sea water will "push up" harder on the boat.
(This will be counted by reducing the volume of displaced water so the bouyancy force will remain the same).
all other things being equal Answer: a) higher in the water.

a) higher. Salt water is more dense than fresh, so the boat displaces less water for the same weight.
Different places in the world have different salinity and other changes in water content. So a typical ship would have a set of Plimsol lines on the side to indicate an expexted water line (to a standard loading or unloaded) for various parts of the world. Its important, so they know what draught the boat will have. Thats especially important when crossing a sill of a lock.

Is this physics or power squadron? If physics then you will need to think about what the difference is between salt and fresh water. If power squadron, then the answer if somewhere in the text. I just wish the other people hadn't told you the answer. Thinking is good for you. It can save your life.

a) Higher in the water because the salt water is more dense
