powersloshin there hasn't been any water in the lake until the last lot of rain , so there shouldn't be any weed or very little but you will need a weed fin any way, going by the first pic the water level would be about the same as in the vids
the vids were taken in a southerly with shallow water and flat, when the lake is full a southerly can be like a washing machine
a thumb to rule is Sydney will get stronger southerlies than jervis bay but jervis bay will have stronger n/easters
we have guys traveling 2 1/2 hrs from Sydney to sail
