I have anchored in amongst the moored boats in Cstad and it is uncomfortably tight. I've used the public moorings just south and east of Round Reef and didn't like the swell there. I've rented a mooring from Jones Maritme in town and thought it was a very good option for town access. http://www.jonesmaritime.com They may also have a slip available for about the same cost as a mooring. I've anchored in Teague Bay to the east when I've been racing in their regatta. It was very comfortable but caution must be used getting behind the reef. I've grabbed a mooring by Fstad and found it too rolly to overnight. I've anchored off of Buck Island, after getting the permit that Baard from Cuvée mentioned previously, and found it quite comfortable along with excellent snorkeling in the nearby marine park.
