Gavin Urquhart, Ben McKinley, Jamie Macmillan and Ben Warren are now on holidays following the disappointing 83-point loss.
The Seagulls dominated the entire afternoon and gave the Tigers no chance to advance to next week's Grand Final.
With Majak Daw out with a broken finger, Werribee was undermanned and overwhelmed.
McKinley finished with three goals, while Ben Ross and Urquhart had two each in what was a lacklustre performance. Macmillan tried hard across half-back and Warren led up well from the forward line but the Tigers were unable to swing any momentum their way.
Williamstown will now play Port Melbourne for the premiership.
