If you are going on a cruise or another kind of sailing trip, it is a good idea to install yourself on the deck with your binoculars. When sailing you typically get to cover larger distances, with the possibility of encountering bird species that are otherwise difficult to see. For example, in the summer months, you may encounter species such as the Long-tailed Skua and the Pomarine Skua in West Greenland (especially in the Disko Bay area), and in August/September the Great Shearwater (a breeding bird from the southern hemisphere) visits the waters between South Greenland and Sisimiut.
