I've kept our boat at Osprey Point Marina in Swan Creek (essentially Rock Hall, MD). Our first season there we did suck up a jelly fish into our A/C intake. But in three years of being in that area, that was the only encounter with jelly fish. Having grown up boating on the Sassafras River, I know that area is nearly free of the creatures. Sometimes in an extremely hot Summer, late in the Summer we might have seen a few.
