In this five-part series, climbers Nico Favresse, Olivier Favresse, Seán Villanueva and Ben Ditto ship out for the summer with Captain Bob Shepton on his 33-foot sailboat in search of unclimbed big walls rising out of Greenland's fjords. The nine first ascents made by the team, and the style in which they were made, garnered them a nomination for the 2011 Piolet d'Or. Video: Seán Villanueva
