My friend Tony Lancashire and his friend Kevin look to be about 1/3 way through the Northwest Passage on the 17' Nordic Boat sailboat. They just spent 5 days stuck in the ice on an ice flow and are back moving again. When I read the blogs it reminds me a lot of Ernest Shackelton's book "South" where he recounts his adventure(?) in the Antartics.
