Simulating a body (boat) moving on water
 

Dear sirs/madams

Trying to simulate a boat or making it simple, a wooden object to move on water.
-Upper layer fluid = air.
-Lower layer of fluid = water.
-Using cell zone>operating conditions, applied in the z direction (direction of movement) 50 m/s^2, and the gravity of -9.8 m/s^2, in the y direction.

No boat movement.

What should I do, any specific settings please? Thanks in advance.
