Would suggest that this is posted in the Victorian Forum.
As you know, Lorne is located in a deep bay, so protected from the prevailing southerly winds and the hills around the town protect it from the Northerlies. Would expect that easterlies may be the go.
You might have to go to Wye River (watch out for the beach break) or back towards Eastern View to sail in the southerlies.
"There have to be a few more places to sail on this bit of coast...."
GP, you need to go down there (after the holidays) just to see the rocks that are in abundance. It is very limited, even for surfers. Cathedral Rock is a classic example.
