You can check out Galloway Creek marina (or something like that) which is at the mouth of the Middle River. Bowely's Quarters marina is just around the corner and may work for you as well. They used to have about 10 cats on the property at Galloway
The next location is Podickory Point Yacht Club at the mouth of the Magothy. Basically right next door to Sandy Point State Park.
That's about it from what the active sailors know.
Take Care

ps check out the CRAC web site for all of the club and regatta info.
