When Kāpiti dangerman Andre Halbert was caught by Dion Sanson in the sixth over, and Daniel Browne lbw to Jesse Parker three balls later, it put the brakes on the early momentum, and they were eventually back in the pavilion at 133-5 off their 20 overs.
It was all too easy in the end for LOB, with opener Jamie Pinfold cruising along to an unbeaten 83 off 56 balls.
LOB reached their target in the 16th over, dropping the wickets of Matthew Wilson (13) and Andrew Simpson (13) along the way, with Dion Sanson the not-out batsman at the other end on 17 at stumps.
Of the bowlers, Fraser Bartholomew, Jesse Parker, Daemon Kennett and Sanson did the job well for LOB, while Carter Andrews and Michael Newell picked up wickets for KOB.
Meanwhile, Paraparaumu would ultimately finish third after beating Marist in their afternoon playoff by six runs after the heroics of bowler and lower-order slogger Sean Windle - who smacked a priceless 29 not out to give his side a defendable total, before taking two wickets in the final over as part of a late Marist collapse that had them come up short.
Those statistics were enough to lift Windle to the top of the MVP standings for the competition, ahead of LOB fast bowler Fraser Bartholomew, and Marist veteran batsman Mark Fraser, who also had a good tournament as wicketkeeper.
Finishing strongly was Property Brokers Wanganui United who, after the disappointment of two losses in the first two rounds the week before, came fifth overall after winning their last pool game with Weraroa CC and then their playoff with Wairarapa's United CC, both by seven wickets.
Player highlights for Wanganui United were Hunter Morrison and Martin Pennefather taking three-wicket bags against Weraroa and United CC respectively, while Andrew Penn scored 58 in the first game of the day.
Very impressive was the form of youngster Carter Hobbs who scored 30 not out against Weraroa, then 56 in quick time in the playoff for fifth.
Although they didn't get the results they wanted on the day, individual highlights for Marist included all-rounder Fraser Kinnerley taking three-for against Levin, and opening batsman Chris Stewart making 74 in the Paraparaumu playoff, finishing as the leading run scorer in the tournament with 139.
The best innings of the tournament was from Paraparaumu's Ajay Kumar, who made 95, while the top bowling performance was shared between Bartholomew and Red Star's Stefan Hook, who both took 4-12.
The next Coastal Challenge Cup tournament will be the two-day format, which starts on November 6.
