Only Jersey captain Ian Gould managed to save a little face by beating Guernsey’s captain Ian Platt in the seventh frame.
But elsewhere Jersey simply had no reply to the Sarnians.
At the Guernsey Ex-Service Club Jersey’s Heys made a good start in the billiards final, with a 37 break.
But by the half way stage Desperques had crept ahead of his opponent and in the second half his potting skills had increasing influence, and he broke away from Heys with breaks of 44 and 41 to lead 344-259.
Playing much better billiards, Heys started to come back into the match, but with only 100 points to go Desperques made the breaks to give him the title 500-391.
In the team snooker, Ady Holley and John Skillet won the first two matches, both 2-0.
The captains’ meeting was much closer.
Guernsey’s Ian Platt had breaks of 36 and 30 to beat Jersey’s Ian Gould 77-30, with Gould conceding on the green.
However, the scores were reversed when Gould, playing well, beat Platt, 57-17 after he conceded on the blue.
Jeremy Gogan came close to taking a frame off Guernsey’s new CI champion Adam Shorto.
Shorto required a snooker with 18 on the table, and got it when Gogan went in-off the blue to allow Shorto to pot the remaining colours and win the frame and match.
In Gogan’s second frame against Shorto, the Jerseyman conceded with one red on the table at 62-6.
With the match already won, the last two frames were between Desperques and Jersey’s Bob Bradshaw.
They were evenly matched in the first frame but Bradshaw lost when Desperques potted an excellent long black.
In the second frame Desperques had the highest break of the night a 65 which was enough to win and Bradshaw conceded, with a red left, on 79-31.
