In a fast paced start to the final, it was Limavady who put the first points on the board, with James Laird converting.
Ballyclare had showed their strong carrying in the opening minutes and they hit back with the first try of the match.
After strong carries from the forwards inside the Limavady 22, it was number eight, Austin Adair, who picked the ball up close to the Limavady tryline and powered over from close range.
Scrum-half, James Woodside, was accurate from the tee to add the extra two points.
Ballyclare then grabbed a quickfire second, after an attack into the Limavady 22. The ball was shot out wide to wing, Ben Vance, who found himself in space ion the right wing. The winger took on his defender in the channel and galloped around the outside for a deadly finish. Woodside's nudge from the difficult angle was well executed.
Woodside would add another penalty conversion to send the Antrim school into a half-time lead of 17-3.
Ballyclare were good value for the lead, with their intensity around the breakdown and strength around set pieces giving them a great platform to work from.
HT: 17-3

Number eight, Austin Adair, showing great power once again to break the Limavady defensive line and surge over to score. Woodside converted once again.

Woodside kept up his 100% record from the tee to make the score 31-3.
Limavady never stopped their work rate but were unable to make any decisive actions and were being pegged back by the intensity of the Ballyclare pack.
