in salt water
Explanation:
The buoyant force acting on a body depends on the volume of body immersed, density of liquid in which the body is immersed and acceleration due to gravity.
Buoyant force = Volume immersed x density of liquid x g
As the density of salt water is more than the fresh water so the buoyant force acting on the boat in salt water is more than the fresh water.
