The Westerners won the prestigious team event, formerly the Etam Trophy, after returning a score of 235 – with three of the four-strong team’s best gross scores counting.
There was a double success for La Moye as former Island champion Corinne Ramskill took the individual prize with the best round of the day – a gross 76.
Ramskill said: ‘It’s a tough competition because it’s strokeplay, but it was a good team effort.
Conditions were very good, there was a little bit of wind but otherwise the course was in very good condition.
‘It’s unusual for me to win an individual prize so I was delighted.
I was three-over-par after nine holes and I thought if I hang in there I might have a chance.
Besides you’ve got to keep going any way for the other members.’ Ramskill finished on a four-over 76 after a mixed round.
On the down side Ramskill three-putted the first; lost a ball at the sixth for a double-bogey while also taking a penalty shot at the 14th.
But there were also three birdies on her card.
Gloria Paradiso, runner-up in the 36-hole Island championship last Friday, returned 79 for La Moye.
Elaine Pushman and Karen Le Brocq carded 80 and 84 respectively.
Royal Guernsey finished second in the team event, nine strokes behind on 244.
Gillian Burford returned 80, Jan Chamberlain 81, Di Andrews 83 and Julie Creed 84.
Royal Jersey were third and Les Mielles fourth.
