hi Brav
Jervis Bay and St. Geoges Basin are great sailing venues - The Basin being flater and the Bay chopier.
I know there are two caravan parks in Husky (slightly up market) and one in Sanctury point - and a camping ground at Green Patch in the Bay - but thats a fair way around the southern peninsula.
Dr surf has a shop at the basin and here's a link to the sailing spots. Give Dave (DR.Surf) a call he may be able to help more.
