The owner is a friend from Massachusetts. The boat is a double-planked 46 ft Aage Nielsen center boarder, built in Denmark, a beautiful boat. She is carrying on for a couple weeks with a different crew, then heading back down to Baddeck. Hudson Strait is definitely a remote part of the world, there aren't all that many safe anchorages, 30 ft +/- tides, no facilities to speak of, and quite a few 'sparsely charted' areas. The currents boil in and out of the strait at 4-5 knots north of Cape Chidley, but it was with some relief that we found the seas fairly smooth given such strong currents.
We came in to a few places in Labrador: Red Bay, Makkovik, and a harbor of refuge near Nain after the wind came around to the north and hammered us. Once it abated we ended up sailing direct from Nain to Kimmirut, as the winds were favorable. A couple of the guys on the boat have cruised Labrador, and love the Torngat (northern Labrador). They didn't seem to think it was particularly difficult sailing, other than the time/distance to get there, but then they had also been to Greenland, Spitzbergen etc. The mantra was always 'in the Arctic, you need patience' to wait out weather, fog etc. We had very little fog other than a couple days near Belle Isle. The most difficult/dangerous part of the trip was watching for ice during the 4-5 hours of darkness off Labrador. In the full moon it was quite easy, but on dark nights we had to slow the boat way down (not always easy when it's blowing 20) and sometimes take bow watches to give the helmsman a bit more warning.
It's the owner's story to tell, hopefully once they're back there will be some on-line accounts. It sure is a beautiful and interesting part of the world, seldom visited by yachts.
