Guernsey FC remain in relegation trouble after a home defeat by mid-table Ramsgate at Footes Lane.
Aaron Millbank put the visitors ahead from the penalty spot after just six minutes after being fouled as he ran onto a weak backpass.
The Rams were in control by half-time thanks to Alfie Paxman's tap-in and Oliver Gray's header.
The result left the Green Lions 21st in the Isthmian League Division One South table.
Chatham Town's 1-1 draw with Three Bridges means Guernsey are now just eight points above the relegation zone and are still searching for their first home win of 2017.
