Sorrento to Rosebud might be good.. But if we do get the forcast 20-30 SW and you don't want to drive that far and have the hassle of needing two people for a car shuffle I would recommend doing loops either at St Kilda or Sandy from out off the end of the breakwater wall and catching runners into the beach where you can paddle across and back up to the wall out of the wind to do it all again.. It can be good fun and great DW practice at catching runners.. St Kilda is probably the better choice and you can park for free on the city side of beach rd near the corner of Langridge st and beach rd.
Have fun doing "loop de loops! - when you feel like a drive - come on down - we've got a couple of options in Port Phillip or Western Port - depending on the wind -- see you down this way one day!
