《Piloting Directions for the Gulf of Finland》 - 免费有声读物

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 Please note that these piloting directions are rather completely out of date.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)
