Western Australian International Optimist Dinghy Association

Welcome to WAIODA.

Our main goal is to bring Optimist sailors and their families together to have some fun!

We provide sailors access to state, national and international regattas while also helping Optimist sailors develop the essential sailing skills and techniques to compete at their best level throughout the sailing season.

This event will be hosted by Royal Perth Yacht Club (Fremantle Annexe) and will see the best young Optimist sailors from around WA compete for the title of state champion. · Read more
