It has been done again a few times. For an interesting account read Arctic Odyssey by Len Sherman who did it in 1995 in a single season. There were three of them in an 8.5 metre steel boat made by Winston Burchill (who was the skipper for the trip).
Winston is a very likeable guy. I met him while cruising the North coast of BC and he signed my book.
I know, who cares, right?
There is a tide in the affairs of men,
Which, taken at the flood, leads on to fortune;
Omitted, all the voyage of their life
Is bound in shallows and in miseries.
Shakespeare, Julius Caesar IV, iii, 217
