Guernsey were given a reminder of how much tougher this step up is going to be as Ramsgate showed no mercy with four first-half goals.
Ollie Schulz opened the scoring with a free header, before James Everitt doubled the lead on 20 minutes and Ian Pulman made it worse on 42 minutes.
And despite missing an absolute sitter, Ramsgate rubbed salt into the wounds with Everitt's second after being left all alone at close range in stoppage-time.
GFC were much improved after the break and played against 10 men after Schulz was sent off for two bookable offences, but the damage was already done.
Youngster Paris Pereira and Etienne Le Prevost gained vital experience by making their debuts from the bench in the second half.
