I posted this some time ago on the interesting boat thread but it seems to me that it also belongs to this thread:
"Any sailboat able to make the Northwest passage will deserve a better look. If that boat is not a purposely built boat well, it is an interesting one, so just have a look at this one, not only crossed the North Atlantic at high latitudes has they went trough the icy Northwest passage. After that they circumnavigated:
The boat was blocked by ice in Peel Sound and they hesitated to go through.
Eventually they found a gap and went through. Some wind pushed them through with considerable speed they reported.
That's true, it is a some year's old Bavaria 44. Basically a standard boat.
It seems that those kevlar protections that the Bavarias have on the front part of the hull come as very handy to break ice
