I'm also curious about this area, being at the base Grenville Channel. Just to the SW of Hartley Bay and on the north side of Promise island is the Coghlan anchorage. I've seen boats in there before but never used it. It looks like the NE part of it has reasonable protection from southerly wind, but there's also a lot of up and down wind from Douglas channel that might get in there. Has anyone anchored in Coghlan in a blow? Murray M might have some local knowledge, living in Kitimat.
I've anchored in Coghlan a number of times. As you guessed, the wind can channel through there when coming from the right direction, but it's still protection none the less. The biggest issue I've had is that the holding varies quite a bit. I think my chain has always rattled across the bottom when swinging, and I have dragged and had to haul and reset before.
