I have heard the rock pile is tight. No intention to ever do it again, especially after your comments.
As to Cumberland, yes, there is more protection if you anchor close to the docks. In our case, the winds were out of the SW when we came in, so what little protection that was available was behind Drum Point Island. On day two, the wind switched to SE and the area along the docks was nicely protected as you say. I sounded the area along the docks and it stays deep closer to land than the charts indicate, so I could have snuggled up. Luckily, the wind was moderate.
I will update that page in the blog post, thanks.
