We’d all like to keep our charts corrected as per the book, but for some of us it isn’t always possible. Perhaps we’re too busy making ends meet, maybe our folio is too huge to contemplate the numbers of Notices to Mariners we’d need, or maybe we’re just bone idle. Whatever our excuse, and however we may mutter about ‘the rocks not moving’, sometimes we really need to be certain where the buoys and lights are. Even if our charts are as old as this one, however, all is not lost. Reed’s Almanac carries lists of all navigation marks for each sea area with positions and characteristics. They’re updated to the most recent publication. Not perfect, but a lot better than most people’s charts!
