As per
www.seabreeze.com.au/forums/topic.asp?TOPIC_ID=8971 - I've always found the Seabreeze search engine works really well

Rego is Wed 1100 - now extended to 1600 due some late overseas arrivals. I will make a call on site and start of comp after registration closes - if forecast is ESE for Thurs morning (as it is now) then we will start early @ South Perth. If/when it swings S we will move to Cott Main Beach. Sat & Sun Main Beach Cott is not available so N-NW-SW-S winds will be @ Dutchies. We have to have everything finished and be back at McCallum Park for presentations by 3pm on Sunday.
We have potentially 3 times as many heats as last year to run so we cannot afford to waste any time/wind - so some heats may have to be run in less than perfect conditions - such is life in competitions - we would like a result so that riders get a chance to take home some good prize money.
