In single phase you don't use VOF as it's a multiphase model. You will also only see pressure and viscous effects. And oops, "not reported separately" for the wave effects. They're included in the pressure & viscous force.
If you chop part of the domain down to the free surface you need to remember that you're not including wake effects etc which distort the free surface. As a result you may find the results differ from the tank tests.
