Students from Perth and Bunbury descended upon Leschenault Inlet for the South West - Head of the River regatta on Sunday, March 31.
The annual regatta saw around 90 of the state's best young rowers compete in 32 events in calm conditions.
John XXIII College took out the Charles Hastie Cup with 178 points overall.
The team then claimed the Ronald Walter Prosser Cup, after winning the Open Mixed Eight race in a time of 2 minutes, 47 seconds.
Bunbury Cathedral Grammar School placed second overall with 66, ahead of Bunbury Catholic College with 36.
Students from Manea Senior College and Eaton Community College also took part in the event.
Participants enjoyed the races, ergo challenges, food (prepared by the Bunbury Rowing Club), and each other's company.
Bunbury Rowing Club captain Mitch Oliver said the event provided a fun environment for competitors, team members, and spectators.
"The event has been running since the early 2000s, and it's an event that the Bunbury Rowing Club runs on its own," he said.
"John XXIII come down on the Saturday, and visit the club for dinner. It makes for a really great social occasion and a good experience for the students.
"The event also makes for a great opportunity to show the community what we do...it's a fantastic opportunity for everyone involved.
"Rowing is very much a team sport, so it's great when everybody gets together."
