Now that you know how to take a bearing and plot a course, the next thing you will need to figure out is where you are. Usually, you can do this well enough by keeping track of where you started and where you went, but sometimes this is not enough. By taking a single bearing you can get a rough idea of your position; by taking two bearings, you can pinpoint your exact location.
We start by taking one or two bearings as in figure below. Using the two known positions is called "Taking a Fix".
To find your location take two bearings as close to 90º apart from each other as is possible. The smaller the angle the larger the margin of error.
As with plotting a course, it is easier to find your location with a Nav-Aid than it is with a hand compass. The Nav-Aid takes care of the variation. The Nav-Aid has two rings of numbers, with the inner ring used for back bearings (180º from the outer ring). The Nav-Aid also can also tell the distance of objects on a chart, helping with single back bearings.
Using a Nav-Aid© is the quickest and easiest way to plot a course. Remember to change the magnetic line on the Nav-Aid© for the area in which you are paddling, as well as the mile marks on the bearing line for the chart you are using. You'll find it convenient to secure the Nav-Aid© to the deck of the kayak and tuck it under the bungie cords when not in use.
