Spent the day dodging lobster pot buoys and lobster boats in heavy fog that didn't lift until we anchored in Rockland. We were both on our toes for hours deciphering shadows and engine sounds in the fog. Did I mention that one guide book says that the Tenants Harbor area has one of the highest density of lobster pots anywhere? I was completely exhausted when we arrived. It cleared for a couple of hours and then rolled in again. We took the dingy ashore and had to navigate thru the fog again on our way back to find Borealis. We would still be hanging onto a lobster pot outside Tenants Harbor if we didn't have a chartplotter and radar.
