Loreto’s girls’ division one crew lived up to pre-race favouritism with an emphatic performance on Lake Wendouree on Sunday.

Grace Hoffmann, Ella Higgins, Laura Foley, Molly Grech and cox Madelyn Rothe comfortably won from Damascus College, which impressed in its girls’ division one debut, while Ballarat Clarendon College was third in the 2000m event.

The Loreto crew had just enough time to celebrate their history-making display before news began to filter through that regatta officials had not given the all clear on the St Patrick’s College victory in the boys’ blue ribbon event.

Regatta referee Eric Waller later confirmed that the St Pat’s cox had weighed in 2kg under the required minimum weight of 55kg.

He said it was his recommendation to the BAS that as this was a breach of the rules St Patrick’s should be disqualified.

The BAS executive officer Sharyn Canny announced more than two hours after the regatta that owing to an inconsistency in the coxswain weigh-in process for the event, that the boys’ final be re-run on Wednesday at 9am.

For Loreto, the breakthrough for the Head of the Lake’s most prestigious comes after a decade of competing at the event.

The college’s biggest previous success in the regatta had been taking out the girls’ premiership in 2015.

The past 25 titles had been shared by Ballarat Grammar School and Ballarat Clarendon College. Ballarat High School last won in 1991.
