Sailtrain Navigation and Chartwork Compass Deviation.
When a vessel is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and use these to establish arcs of position and lines of position on a chart. A fix consisting of only radar information is called a radar fix.... A nautical chart is a graphic representation of a sea area and adjacent coastal regions. Depending on the scale of the chart, it may show depths of water and heights of land (topographic map), natural features of the seabed, details of the coastline, navigational hazards, locations of natural and human-made aids to navigation, information on

• Take bearings on the beam first, and those directly ahead or astern last. • When measuring objects to determine a line of position, measure first those which have the greatest rate of change in the quantity being measured; measure last those which have the least rate of change in that quantity. how to draw smile dog First, take a bearing on the lighthouse, then plot that bearing with a line running through the charted location of the lighthouse. Next, take a second bearing on the stacks, and plot that line on your chart. Your exact location is where those lines, called lines of position or LOP, intersect. Some notes of caution. Do not use water based aids to navigation (ATONs) as they can be off station

- Bearings and headings are readings from the compass or the chart. The heading of the boat is simply what the ship's compass reads at any given time, it is the direction in which the boat is headed. Bearings are compass readings to objects outside the boat as in; That freighter is bearing 035° or, that lighthouse is bearing …
