Another important skill for the coastal pilot is seeing. Well, yeah,
not many blind people in the game. But seeing is not just watching the pictures your eyes throw up on the screen of your consciousness and waiting for things to jump out at you. The signals your brain sends back to your eyes are at least as important as what your eyes send upstairs. I often used to sail back into Boston late at night. This was in the very simply equipped Pearson 26's. They had navigation lights but not even a compass light. I rigged up my own portable one that I moved from boat to boat. Chart, watch, compass, pencil and parallel rule. That was the full navigation outfit. I was usually cold and in a hurry by that time so I would take the short cut between Lower Middle shoals and Governors Island Flats rather than loop around the main channel. There was never much traffic in there which was a plus but there isn't much margin to either side for a deep keeled boat. I'd swing close around Deer Island Light, check the compass course on the chart and that was about the last I would see of the chart until the next time I went sailing. There was too much going on in the harbor to spend any time looking at it and I didn't want to lose a bit of my night vision anyway. The first thing I had to find was the C "1". They were black in those days and just as dark as the night. I seldom actually saw the can. Instead, I would sail intentionally a bit off course and watch the solid mass of city lights behind until I saw one wink off. When a blink caught my eye, I would watch to see if there was a progression of lights winking off. When I found a steady progress of lights disappearing, I would then sail straight towards the spot while watching for the lights on either side to go out briefly. Cross referencing with the compass course to be sure I wasn't chasing something else would bring me right up to the can. The distance I could actually see it was short enough that I could have hunted for it all night looking directly. (Binoculars would have helped but I had good eyes and it hadn't occurred to me to buy a pair.) I would then head up towards the N "4", pick up the C "3" the same way and head directly towards it when I found it. Then straight up the channel again which would give me the bias to move the C "5" against the lights. Once past this, I was home free. Obviously this isn't a technique that will work most places but is shows the difference between just staring off into the dark waiting for the little guy in your brain to yell "Buoy!" and looking with strategy and planning at the full picture in front of you. The brain is capable of some very complex processing when given a chance. I used to read about grizzled old salts being able to read the current in the waves and wrote it off as folklore. How can you determine the speed and direction of the current without a reference point? One day, I looked at the water and realized that young salts can do it too if they just learn how to see. After you have looked at waves for a while, you develop a feel for the relationship of speed to length (there is an exact relationship) and the direction is, of course, fairly easy to determine. When you look "through" the waves to the surface of the water the right way, your brain can actually synthesize a stationary reference by subtracting the wave motion. You can then see the bubbles and bits of flotsam clearly moving very separately from it. I don't know how this can be taught or even if everyone can do it. Once you've seen it, it's very striking. It's a very Zen like realization to discover that it was always there but you couldn't see it. You obviously wouldn't want to thread a very fine piloting needle using this as a current correction but it's very useful in an area where current direction is not obvious and to alert you to the direction and rough strength of the set. These are narrow examples of a way of using your brain that should permeate all your piloting, whether simple clock and compass or the fully outfitted bridge of a major ship. Everything is just little pieces for an internal mental model of your situation that you maneuver within. As soon as you start just pushing a pencil dot across a piece of paper or a cursor across a GPS screen, you may be standing into trouble. -- Roger Long |
