Ive paddled some of this, in 2006 I did Port Hardy to Bella Bella (I think I stayed in that cabin for a couple of days) We were going north and had to wait for a week just south of cape caution, for the conditions to improve. Looks like a great paddle.

You probable stayed in the cabin on Burnett Bay North which is located South of Cape Caution. The one at Cranstown Point was built about 5 years ago. It was a fantastic trip. Pictures are at photos.app.goo.gl/xZtCdE1upcsBS9RUA

Two minutes in, that's mist not fog. Maybe educate yourself about the difference.
