The Western Australian International Optimist Dinghy Association (WAIODA) is the home of Optimist sailing in WA. As a volunteer-led organisation, we support junior sailors, families, and clubs through coaching programs, regattas, and development opportunities that build skills, confidence, and a lifelong love of sailing.
WA has a unique place in the history of Australian Optimist sailing — we were the first state to adopt the class, nearly a decade ahead of the rest of the country. Today, that pioneering spirit continues as WA sailors regularly compete — and succeed — at national and international levels.
Our mission is to grow the sport by fostering a fun, inclusive, and high-quality sailing experience for young people across the state.

What we provide:
Training Clinics
Led by the best coaches in WA, our clinics include on-water drills and practise races, as well as on-land fitness, technical sessions on rigging, and theory addressing strategies and tactics.

Coaching
WAIODA is fortunate to be supported by a strong network of experienced youth and senior sailors who are appropriately credentialled. This includes State, National and Olympic-level sailors, as well as trained educators with extensive experience working with children and young sailors.
Teams Racing
Optimist Teams Racing is a fast-paced format where sailors compete as a team rather than for an individual result. Success depends on communication, tactics and helping teammates achieve the best combined outcome.
WAIODA supports teams racing as an important part of sailor development hosting the WA Team Racing Championship and entering one or more WA teams in the Australian Optimist Teams Racing Championship each year.
Teams racing builds tactical awareness, decision-making and teamwork, while offering sailors a very different racing experience from traditional fleet racing.

WA Optimist State Championship
Each summer season WAIODA hosts the WA Optimist State Championship where sailors compete for the title of WA State Champion, Girl Champion and Junior Champion.

Australian National Championship
The Australian Optimist National Championship is held in each January and brings together Optimist sailors from across Australian overseas for a major week of racing, development and community.
WAIODA supports a Team WA campaign each year, coordinating coaching, rhibs and training opportunities and coordinated preparation for participating sailors.
In January 2028, the Australian Optimist National Championship will return to WA and be hosted by Fremantle Sailing Club. This will be a significant event for the WA Optimist community and an exciting opportunity for local sailors across Green, Intermediate and Open Fleet to build towards competing on home waters.

International Continental Regattas
WAIODA members are eligible for selection into the Australian Optimist Sailing Team (AOST) or Australian Optimist Development Squad (AODS) which provides a pathway to the Asian & Oceanian Championship, European Championship and the World Championship.
