Hi Michael,
Have called LCSC, spoke to Vice Commodore and they generally get less breeze than say Moreton Bay or open water plus having flat water which means they sail up to around 25 Knots.
It suggests they will be sailing so maybe look at Cootharaba for a sail.
BOM still has 20 - 25 from SE for Sunday.
Its always a bit hard to guess what will actually come in.
Could make a decision at 8.00 on Sunday morning if you like as that leaves enough time to go any of them.
Will send you PM with my phone numbers.
