Shortening the Night

26 July 2020 Gianluca Casagrande

10.30 UTC – Several messages from the skipper this morning provided an update about the current situation of NANUQ’s leg 19 to Iceland. After a slight deviation yesterday to keep clear of a large area of bad weather, the boat is following a rather northerly route towards her destination. This allows to take advantage of favourable conditions, with good weather and fair, steady winds from the most appropriate directions. NANUQ has been travelling on sail at an average speed of 9 knots for most of the last 24 hours. During her cruise, she is slowly closing in to the Arctic Circle and as it is typical of this season, while Latitude increases, the crew is experiencing a correspondingly increasing duration of daylight. Longer sunsets give way to shorter nights and to earlier, longer dawns.
