This Swalec Bowl second round tie proved to be very entertaining for the decent crowd that attended, with a hatful of tries scored, but this was often down to some sloppy defending by the hosts rather than the creativity of the Cocklemen.
The home side had started off well and it was not long before attacking full back John Lumb had made one of his trademark breaks from deep, and the Cardis soon got the edge in the scrum as well.
When Lumb broke from deep, the long sweeping move was finished off by winger Rhydian Jenkins to open their scoring.
Scrum half Luke Rogers saw his conversion attempt hit one of the uprights.
Stand-off Llyr Jones added the second try, after an initial charge by skipper Llyr Griffiths off the base of the scrum was taken on by hooker Rhys Brock - but Rogers’ conversion attempt was charged down.
Openside Mike Williams, one of the stand-out performers for the visitors, hit back with a try, following a good period of pressure, and the conversion by centre Tom Jameson took the score to 10-7.
A minute later, however, the scores were level at 10-10 when home scrum half Owen Thomas slotted over a drop goal.
After the interval, the home side scored a try almost from kick-off when flanker Sion Hughes was on hand to take the ball off centre Emyr Harries, following a fine break, and this was converted by Rogers.
The scrum half crossed himself for a try soon after, when he was on hand to round off a superb move, with prop Tomos Evans and centre Harries having made the inroads with great breaks from deep. It was also converted for a 24-10 lead.
Back came Laugharne, however, and they replied with a try from loose head prop Rhys Thomas, which was converted from the touchline by centre Jameson.
Coach Colin Horscroft reshuffled his team in the final quarter and brought on Colin Davies to replace blind side Gareth Clifford, who had another good game.
Within a minute Davies was instrumental in putting Rogers over for his second try, and Lumb added his second try soon afterwards after he was put away, thanks to a sublime inside pass from Harries.
Laugharne responded again with a try by second row Gary Jones, which was converted to bring them back to 38-24.
Replacement flanker Kieran Hurley, grabbed an opportunist charge down try in the closing minutes which was converted by Rogers, but it was the visitors who had the final say when flanker Williams rounded off a fine individual performance with a try to complete the scoring.
