Brad,
What sort of motor do you have?
I used a 5hp and with the east Australian current I coundnt believe how fast the trip was from fly point to kogarah bay motorsailing with a light northeaster.
As said before, there isnt a lot to worry about, just give the north head of botany bay a bit of room.
The planes are great to watch, the eddies from the jetwash can make racing in light winds interesting!!
