On the conditions the 941 sailors registered so far to sail in Perth will face Parkinson said, "Perth is renowned as one of the windiest cities in the world and in December the sea breeze is 20-25 knots guaranteed every afternoon.
"I know for test event last year we had unexpected light winds but the summer hadn't really kicked in but my bet is there is strong easterlies in the morning and the wind goes to nothing for an hour and then the strong breezes come in from about 12:30 and keep increasing throughout the afternoon.
"It'll be great conditions for sailing and they'll put on a great show for watching."
