We went down to Solomons last Thursday. observed very little debris, mostly at the mouth of the South and West Rivers. One the way back yesterday, wifey saw two relatively small/short chunks southwest of the WR1 just before we started through the crab pot field... IOW, not much of a deal.
Swan Creek, eastern shore, north end of Rock Hall, would be a better anchorage than Hart-Miller, I think, and that doesn't take you north of the Patapsco entrance. The (small) restaurant at Osprey Point marina has been outstanding, and there are other options if you want to go ashore.
(You'll see boats crossing Swan Point Bar northwestward using the range that starts just north of R4, the taller range marker will be behind you, near Grays Inn Creek on the chart. Given your draft, I don't think I'd try that unless following a local boat of known similar draft, and at high tide. I think safer to head further south and then around G3 before turning northwest. It's not really a much further distance, in the grand scheme of things...)
Bodkin Creek could be another decent anchorage, western shore, just near the south entrance to the Patapsco. If it's useful, the restaurant in there at Pleasure Cove Marina used to be called the Cheshire Crab, decent at the time, but we haven't been in there for a while...
