Clevedon’s points came courtesy of a fine Oscar James try and six points from the boot of Will Carpenter, but they rarely threatened the visitors, who were good value for their bonus-point win.
The home side got off to the worst possible start, as a Camborne penalty in midfield was kicked deep into Clevedon territory and from the resulting lineout, Sam Matavesi touched down for his side’s opening score.
The conversion was missed, but Camborne didn’t take long to double their advantage.
After Mike Lowis was sin-binned for an adjudged infringement at the breakdown, Matavesi barged over for his second on the 20 minute mark, with the conversion making it 12-0.
Clevedon awoke briefly and a period of sustained possession and territory saw them force a penalty, which Carpenter knocked over for 12-3.
The fly-half added a second minutes before the break to send the sides into half-time with the score at 12-6.
But Camborne were quickly into the stride after the interval and scored their third and fourth tries in quick succession to open up a 26-6 lead.
Clevedon refused to lie down and briefly threatened to find a route back into the game, when winger Oscar James scorched over for the try of the game, tip-toeing along the touchline before sprinting 50 metres to round off a neat handling move on the blindside.
The conversion was missed and Camborne soon had the final say with a try three minutes from time, as Matavesi completed his hat-trick from the back of another driving maul.
Harley Foley was the standout performer for the home side with a characteristically dogged display in the second-row, but it wasn’t enough for Clevedon, who will be hoping to get back to winning ways when they travel to Bideford on Saturday.
