"AWRC's Richard Brock finished off a spectacular season by taking out the event in the Masters F Grade Single, just ahead of clubmates Harry Lillington in the under-18 single and Luke Watts and Hugh Pawson in a mixed-grade premier/under-21 double.

Brock's 29min 4sec time was 78.44 per cent for the prognostic, while Lillington (27min 5sec) was 77.96 per cent and the doubles crew (24min 13sec) was close behind with 77.69 per cent.
The Collegiate under-17 girls' coxed four and the St Pat's under-17 men's pair rounded out the top five places.
