The NOR for the Nationals states

3. Eligibility

3.6  Competitors competing in the championship shall sail only in boats correctly registered or in boats supplied by the official charter supplier for the championship. See NOR clause 15. 


8. Measurement 

8.1  All boats in Open and Intermediate Fleet shall produce a Sail Measurement Certificate and IODA Measurement Book with the relevant sailor’s details duly entered in the AIODA Boat Register. Green Fleet boats shall comply with Attachment 1 of this NOR. 


Attachment 1. Green Fleet 

In the Green Fleet equipment used is not required to hold current measurement certificates (alters International Optimist Class rule 2.4.1) however the following measurement criteria still apply as a minimum: 

a. Hull: the hull to be used shall carry a valid ISAF/IYRU plaque;
b. Sail: the sail shall carry a properly allocated and registered sail number and an IODA sail button; and
c. Equipment: shall carry all safety equipment listed in the equipment checklist. 


The relevant Optimist Class Rules state

2.4.1  No boat is permitted to race in the class unless it has a valid measurement certificate. 

This rule may be suspended in the case of charter boats at any event with the permission of the IODA Executive Committee. 


What this means for sailors entering the Nationals is, you either use your own boat, correctly registered in your name, or a charter boat with a sail displaying the sail number from your own correctly registered boat. 

If you are in green fleet, your boat needs to be registered with the AIODA registrar and have a proper sail number, but you don’t have to show the measurement book or sail measurement form at registration.


If you lease a boat from your sailing club and want to use that boat at the Nationals, please bring a copy of the measurement book first page showing the club as owner, and a copy of the lease agreement, as well as a copy of the insurance policy for the boat. Check that the club boat has racing foils, as school or training foils are not race legal.


In the case of Overseas sailors, they can either use a charter boat or bring their own boat. If they use their own boat, they must bring the measurement book showing the boat is correctly registered in their countries’ Optimist Register. Overseas sailors using a charter boat with their own sail, must bring a sail measurement certificate for their sail.


If anyone has any questions, please email me at aiodaregistrar@gmail.com or give me a call on 0422 995 711.

At the first desk .. you  will need to confirm : Your sail number, date of birth, name at the first stop, then you may pick up your Welcome pack.

Let the Measurer know as you go through the Measurement tent, they will take your sail and have another Measurer complete this for you to collect later.  The “Safety & Measurement form” will be signed with a note that the sail is presently being measured – you will still be able to Register with this.

The cost of Measurement of sail & numbers is $40 – for numbers only it is $15  - please have this amount in cash ready to pay at the Measurement tent.
