Dec 24, 2021 · How do you plot a sailing course on a chart? When shaping a sailing course , plot a line on the chart joining the departure point ( A ) and the destination (B). The navigation chart symbol is signified by marking two arrowheads on the line and called the [ Ground Track ] and is the course to be followed, over the ground, to the destination.

Plan your course right up to the edge of the current. Then do a CTS calculation to get a heading to steer through the current, and drop a mark on the other side of the current on that range and bearing. When you get to the current zone out on the water you will point to the correct amount up current to sail the CTS.

Plotting is the process of keeping track of the position of a vessel over time. This is done by recording the successive positions of the vessel in the nautical chart. The position can be obtained by dead reckoning or by taking bearings from prominent charted landmarks and constructing Lines-of-Position.

It provides water depths, locations of dangers to navigation, locations and characteristics of aids to navigation, anchorages, and other features. The nautical chart is essential for safe navigation. Mariners use charts to plan voyages and navigate ships safely and economically.Oct 13, 2021
Primary method of position fixing There should always be at least two method of position fixing. Now at open sea, the primary method is GPS and secondary method would be “celestial fix”. If there is a radar conspicuous object, the primary method of position fixing becomes the “radar fix”.May 6, 2017

Plot a route on a map To start drawing your route simply doubleclick on the map to set the starting pinpoint, then continue to click each of the points along the route you wish to follow. You can change the map view to satellite, hybrid or terrain using the selector on the top left corner of the route map.
Place the compass flat on the map. Rotate the map until the "north lines" on the map (a series of evenly spaced parallel lines drawn across the map, all pointing to magnetic north) are aligned with the compass needle. The map should now be oriented to the terrain.
A nautical chart is like a road map. It shows you the expected lay of the land and gives references for finding your way to somewhere when don't know the path.
When land shows on a chart, it may show standpipes, towers, flagpoles and other permanent structures if they may be helpful to navigation. You can sight these with a compass to get your position and use them to get your bearings. In the sample below, you can find a monument, a tower, and a chimney as visible landmarks from the water.
The most useful information on the chart is the various marks and symbols. Every sailor should have a copy of U.S. Chart Number 1, the master list of all symbols, signs and objects you will see on any U.S. government chart. Some details may vary on charts from other countries, but most of the symbols and abbreviations are used on almost all English language charts. It's a great reference to learn chart reading and is available as a free download. You can also order a paper copy for your nav station.
In order to read a chart, you interpret longitude and latitude lines to determine your coordinates, which is your position. You have to understand and interpret different symbols like depth, scale, and navigation marks. Using these symbols, you find a safe course and plot it on the chart.
Lines of latitude range from 0° at the equator to 90° at the poles and run parallel to the equator. Lines of longitude run from the north to the south start at 0° in Greenwich, England and run to 180° West and East.
There are several was to use dividers to measure your leg lengths, you'll figure out which works best for you and some techniques work better in some situations than others.
Somewhere on the chart will be a bit of text describing in some detail what the chart is. Not all of this applies to plotting a basic route, but it's good to know things like how old the chart is.
Draw a line from A to be, and measure and note it’s length (8 miles) and direction. If your boat speed is eight knots, it will take you an hour to sail from A to B normally. This means you will be exposed to one hour of current - so the current will sweep you 2.5nm in that time.
If your autopilot isn't integrated with your GPS, you will adjust it step by step to the course to steer as your GPS changes waypoints. You're all set if you put in the CTS calculation in the course, just follow the numbers.
Many autopilots have a Cross Track Error (or "CTE") mode of navigation. In normal course mode, most autopilots point at the next programmed mark, which works well enough without big currents.
