Club secretary Tracey Pedersen said the annual event was a "wonderful opportunity to welcome rowers to Wānaka when the town is at its autumn best".
"We were so keen as a club to host a fun, affordable and competitive event. It’s the first time the club has hosted a regatta of this size, and it was a big logistical challenge — but we’re feeling pretty proud of the way it all came together".
It was "all hands on deck" for the club to host the two-day championship regatta and gala prizegiving event, she said.
Friday’s challenging, choppy water meant some of the long course races were slightly abbreviated.
"The water conditions certainly tested the stamina and skill of crews, but with many competitors not lacking experience, the programme went well. Saturday saw absolute ‘bluebird’ conditions, flat water and a full schedule of excellent racing."
The Mercer Trophy for the club with the most wins went to the Picton club.
Wānaka rowers won five gold medals and placed in another 14 races.
