To register a new boat and get a sail number, or to transfer ownership of a boat complete the Measurement Certificate Application
Even if this application is for a Transfer of Ownership, you will need to upload a PDF of the Measurement Certificate (first 2 pages) and the Blue Measurement Form (all 4 pages) from your Optimist Registration and Measurement Book. To save phone photos as a PDF, use the Adobe Scan app.
COST: The cost for a Measurement Certificate is $47.
Please note - If you think the boat will be used by more than one child in a family, please either just put your Family name in the Owner/Skipper field in the online form, or put all your children’s names. This will means you will not need a new certificate if the boat is transferred between siblings.
Note - Sail Numbers for new boats are assigned consecutively as per the Class Rules
