Tagging along with a couple of the others re the time frame. That is my biggest concern. Distance over ground is approx 180nms. Too far to do in three days in this situation. At least double the time and like others suggest do it in day hops not overnighters.
(All of which is said by someone who has never sailed off Nova Scotia and so has no idea of conditions, weather patterns etc, though I would think it could get nasty.)
