Personal observation

Tide tables are all right, and GPS can be very helpful, but for accurate information you can’t beat your own eyes. Around the turn of the tide, look for direct evidence. A lobster pot marker is the best atlas in the world. If you’re moored, don’t look in the book, look over the side.

In thick fog, if you come upon a buoy, stem the tide alongside it. When the situation has become stable, read your log and your compass. The log gives you the speed of the stream, your compass offers you the reciprocal of its direction. No tide tables or GPS can beat that, but remember that your information is similar in one respect to that given by a diamond. Two hundred metres away, things may nor be quite the same. Look at the terrain on the chart and make an intelligent guess, then plot your next heading, but leave a wide margin for error all the same.
