Changing the time a new boat receives it’s sail number is impractical as it requires two trips to the sail maker, not a problem if you live around the corner, but a time consuming and costly task if you live interstate.
The problem at the moment is not the rules but how they are being enforced. We have a register of boats on the Website simply add a couple of columns of information containing measurement date or dates if measured more than once and measurers name. This list then can be moved to the National Site and updated by all states.
This will help cover a number problems;
One:- All sailors can view the information if they suspect a boat is sailing without a measurement certificate.
Two:- Sailors looking to buy a boat can check to see if it has been measured.
Three:- Sailors intending on sailing at titles will have to make sure their boat is on the list before entering or risk being refused entry.
Four:- Sailors rebuilding/changing require a new measurement certificate and this can be tracked if not by the owner then by other sailors.
