Guy in uniform standing on the side of a boat moving through the water.
A man in the Navy stands on a boat in the cool air.
Not every guy in uniform is in the navy. just because a man is standing on the boat does not mean that the air is cool.
Being in uniform does not necessarily imply being in the Navy and cool air can not be determined from moving through the water on the side of a boat.
Not all people in uniform on a boat are in the Navy
