Crossing from Denmark was total flat calm. Crew said they had never seen it so calm - barely a ripple. Saw lots of wildlife - unidentified large whale, large pod of pilot whales, large pod of dolphins, gannet, fulmar, various gulls, arctic skua, long-tailed skua, arctic tern, wagtail and dunlin (on the deck), puffin. 30 hour crossing, very comfortable and not at all boring.
