That would be a pretty long ride in a dinghy at night, particularly if conditions weren't completely calm or if you don't have a dinghy that gets up on plane. Not a chance in H-E-double hockey sticks I'd try it.
I'd imagine the farther away you get from GH the less crazy the anchorages are but haven't tried it.
If I can't be a good example, I'll just have to be a horrible warning.
