In atrocious conditions on Saturday afternoon - strong winds and heavy rain made this fixture a less than skilful affair - the Cats booted five goals to nil in the third quarter and turned a nine-point advantage at half time into a 41-point buffer, all but ending the contest.
The 9.21 (75) to 3.7 (25) result moves Geelong to 14-6 and keeps them behind fourth-place the Brisbane Lions only on percentage and level on wins with Melbourne, which is yet to play this weekend. It was Fremantle's lowest-ever score in the AFL.
With matches against Adelaide (away) and Hawthorn back at Skilled Stadium in the run home, a double chance is very much a live option for Mark Thompson's men.
It also maintains the club's unbeaten run at Skilled Stadium in 2004, with seven victories from as many matches.
The defeat is a big blow for Fremantle, which drops its second straight match and falls to an 11-9 win-loss record.
With tough matches to end the home-and-away season - the Dockers take on cross-town rivals the West Coast Eagles next week and St Kilda at Telstra Dome in round 22 - the port club is in real danger of missing the September action.
The visitors were very much in the contest at the main interval but had no answer in the third period, where Geelong launched wave upon wave of attacking thrusts, Steve Johnson and Peter Riccardi each booting two goals to decide the contest.
The only interest remaining in the final term was whether the Dockers could avoid posting the lowest score in their history. They couldn't, with the 3.7 (25) total eclipsing their 1996 effort against Adelaide, where they scored 5.6 (36).
The Dockers did not score a goal after half-time.
Given the muddy, slippery conditions on the ground, it was a match where hard work and persistent effort was going to be the order of the day and Geelong had in spades players who were prepared to do just that for the each of the four quarters.
Gary Ablett's hardness and ability in close posed a threat all afternoon. He might not have scored any goals, but helped set up numerous attacking opportunities and got plenty of the footy.
The competition's premier defender in Matthew Scarlett was again supreme, reading the play superbly and showing great poise in the slippery conditions.
Geelong had first use of the howling breeze and dominated from the beginning but weren't able to take full advantage, booting nine behinds before Joel Corey slotted one through right on the quarter-time siren - the only goal of the term - to give his side a 14-point advantage.
Fremantle looked at its most cohesive in the second quarter where it kicked all of its three goals and closed to within a point.
Its best players were defender Scott Thornton, who picked up plenty of possessions marked the ball well in the wet. Skipper Peter Bell and Paul Hasleby were also good, but the Dockers weren't able to run with the Cats for the entire four quarters.
A disappointed Fremantle coach Chris Connolly thought the Cats were in a different class to his team.
"We had our opportunities maybe to get a few more goals in the first half but certainly after half-time our defenders dropped off and in these conditions you can't."
"Geelong's forwards were good enough to grab the opportunities and really get some scoreboard pressure and the confidence for them went one way and the confidence for us went the other."
"The game was played on Geelong's terms and they played very well, they are a class team."
