Jersey's Team Jets remain on course for a play-off place in Premier League Three after beating Falcons Black 58-32 at Les Ormes.
They turned around an 11-9 first-quarter deficit to lead 30-16 at half-time and never lost their advantage.
The victory kept the island side third in the division, four points behind Kent County and Ryland.
"I'm absolutely delighted, it just shows how much we've progressed all season," said coach Linda Andrews.
"I thought the second quarter was just totally dominant in every single area."
Jersey have two home games left this season against the teams immediately below them, Norfolk United and Linden.
