It's a fantastic playground. One of my very favourites!

The speed course for southerly winds is about 2cm in from the right hand side of the picture. It is quite tide dependant, even critical, but the blasting across the bay is great anytime!
The beautiful spit in the middle is not lined up properly for sailing in the prevailing south winds, but there are great possibilities as Decrepit says on Westerlies or Easterlies! Almost all the light coloured shallows are knee to chest deep. Shallow enough to easily spot the Noahs!

There are myriad of other possible high class speed spots in Shark Bay, some of them already explored by Hardie, Crasher, Sammy and a few other intrepid hard men, but access is by serious 4WD or Boat for most of them (I heard some epic stories

). Access to the Boobays area is relatively easy.

It is literally the 'Wild West' frontier of windsurfing!
The Nanga Bay Resort where we camped is on the coast on the other side of the peninsula in the top middle of the above picture. In keeping with the remoteness, there is no mobile phone coverage or internet at the campground.
I had great fun exploring that whole area, and more, on my trail bike on mornings before the wind got up. It really is spectacular, and very remote, country.
Here is another pic I found a while back:
