有声读物: Piloting Directions for the Gulf of Finland

Norie's series of piloting and sailing directions was something of a staple in the chart-room of 19th century British (and other) merchant vessels. The description of landmarks and ports, as well as the rules and regulations provide another viewpoint to an earlier age. Please note that these piloting directions are rather completely out of date. They are given here for purposes of historical interest only, and should not be used for navigation purposes. (Summary by P Hirvonen)
