Coached by Rowen Shepherd, who twice won the event for Melrose alongside current club skipper Bryan Redpath, the Sharks started with an impressive 49-0 win over Hawick before moving on to dispose of Scottish Thistles (a Scottish select side) 24-7.
In the semi-final things got tougher, but they emerged victorious by 35-26 against famous New Zealand club Ponsonby.
In the Final, Sharks were up against Stellenbosch University – from South Africa – and won an exciting contest by 31-24.
Anthony Elliot and Chris Mayor each scored twice but the award for the try of the match went to Vaughan Going, who finished off an excellent move prompted by a break by James Moore.
"We used everyone in the squad as much as possible and it was a smart move bringing on James Moore's fresh legs in the Final," said Shepherd.
"Apollo Perelini made an impact when we brought him off the bench and Richard Wilks proved an excellent captain."
