Yea sounds great Clarence.
You're a lucky man to, not only, drive for a sail, but get taxi'd as well... far out. I thought I had it all!
Great Oyster bay has so many options, but being ~15km wide, and prevailing winds all offshore, there is a lot of ocean in front of you.
Thanks to gear failure, I've been rescued by so many boaters, and spent hours on the Coles Bay island that many times in some pretty wild weather.
Everything from UJ's, masts, fins and winds to 140km.
The swell that comes in on anything with a S in it gets a good couple of meters in it too, things can get pretty messy once you get out there, and not easy to tell from the shore!
We'll be doing slalom/freeride runs up and down from Swanwick to Swansea next time, making sure we have a backup plan, but on the right wind.
It's a superb area to sail, and if the wind is coming the other way, you can drive to the other side of the peninsular in around 45mins. I'd be carrying a phone or having a support craft if you're planning something big offshore though.
A great run that I used to do on my One Design was below - around 20km all up, in the summer seabreeze NE'ers 15-20kn every afternoon.
Highly recommend it.
