Chasing a reduced target of 108 in 24 overs, Moosai, who were struggling from the word go, were finally put out of their misery when they were dismissed for 92 midway through the final over.
Central Sports, had actually accumulated 125 for the loss of five wickets in 28 overs but the target was revised after a second rain interruption around 4 p.m.
Just after mid-day, the first delay had lasted for some two hours and robbed each side of 12 overs batting.
Moosai began in disastrous fashion when openers James Dodds and Neil Persad were both dismissed with the score on 11 and when rain chased the players off the field they were reeling on 19 for three with 10 overs already gone.
The second stoppage lasted less than half-hour but when they returned the pattern continued as wickets kept falling at regular intervals.
Only skipper Aniel Rajah (18) and West Indies fast bowler Ian Bishop (15) reached double figures as Rukham Ramoutar completely dominated proceedings. The veteran off-spinner picked up four wickets for 27 runs and received admirable support from Mahadeo Bodoe and former West Indies wicket-keeper David Williams, who took two wickets apiece.
Williams must have been disappointed when he lost the toss and was sent in to bat under overcast skies. And there must have been more concern when former West Indies quickie Anthony Gray bowled Anderson Persad with just nine runs on the board.
But national opener Daren Ganga and Gavri Ramlogan then added 77 valuable runs which proved to be the match-winning partnership. Ramlogan fell one short of what would have been a well-deserved half-century and Ganga notched 34.
Williams and Bodoe then kept up the momentum with 14 and 12 respectively. The first-time champions thwarted Moosai's attempt to win the title for the third time in four years and picked up $8,000 for the their efforts.
