You can obtain a fix by combining two or more distances or distances and compass bearings. This is how you plot a fix position combining two or more distances: Let's assume you sail near the coast. The radar is in good working condition and in operation. Taking into account your last position, and after comparing the nautical chart's coast line with that on the radar screen, you spot two points on the screen, A and B, from where you can take distances. The equivalent ones on the nautical chart are points A and B. Using the radar's range marker you measure a distance of 5.2 nautical miles from point A, and 2.8 nautical miles from point B. You note the time - let's assume it is 0930 hours. Then return to the nautical chart, and using the dividers, span a distance of 5.2 nautical mil...
What is NAUTICAL MILE? What does NAUTICAL MILE mean? NAUTICAL MILE meaning - NAUTICAL MILE definition -NAUTICAL MILE length - NAUTICAL MILE explanation.

A nautical mile (symbol M, NM or nmi) is a unit of distance, set by international agreement as being exactly 1852 meters (about 6,076 feet), compared with the 5,280 feet in a statute mile. Historically, it was defined as the distance spanned by one minute of arc along a meridian of the Earth (north-south), and developed from the sea mile and the related geographical mile.

We have been filming the Distant Shores sailing adventure TV series since 1998. The show has been translated into 28 languages and seen by many millions on television stations around the world. So here's a peak into how we make our Sailing Television video series - and what it costs to produce… All 130 half hour episodes of the Distant Shores TV show are also available on DVD and download at: http://www.distantshores.ca/sailingdv... This on-going television series following the Shards' global sailing adventures can be viewed on AWE TV in the USA and Caribbean. Watch it on Nautical Channel in Europe, Asia, Africa and many other countries around the world. http://nauticalchannel.com/shows/show/distant-shores
The nautical mile (symbol M, NM or nmi) is a unit of distance that is approximately one minute of arc measured along any meridian. By international agreement it has been set at 1,852 metres exactly (about 6,076 feet). It is a non-SI unit (although accepted for use in the International System of Units by the BIPM) used especially by navigators in the shipping and aviation industries, and also in polar exploration. It is commonly used in international law and treaties, especially regarding the limits of territorial waters. It developed from the sea mile and the related geographical mile.

Part 2 of my CRP5 series, showing the way to use a CRP-5 to convert distances. The most useful conversions to know are: 1m = 3.28ft 1nm = 1,852m 1nm = 1.852km 1nm = 6,080ft 1nm = 1.15sm 1sm = 1,610m 1sm = 1.610km
Answer to Navigation question 10 - Use dividers to on the Timor Sea chart below to find the distance in nautical miles between : a) the peak on Moa and the northern lighthouse on Wetar b) the lighthouses on Kisar and Lakor c) Recon light and the peak on Babar
This video shows how to use the nautical slide rule. Given two of the variables of speed and distance, the slide rule will calculate the other.
This video is a basic introduction to sea charts. We will go through how to read depths and bridge heights, plot magnetic and true courses from the compass rose using a parallel ruler and how to measure distance in nautical miles. In particular detail is information on converting from magnetic to true and from true to magnetic. This is on of the fundamental skills required for coastal navigation.
In this tutorial, Jennifer shows how you can use a location's latitude to determine how far north or south it is from another location. The same process can be used to calculate how far east or west a location is from another using longitude. One important reminder that is shown is how many minutes of latitude are in one degree of longitude.
This video is part 2 of the "Getting Started in Celestial Navigation" video series. Part 2 of "Getting Started in Celestial Navigation," (The Noon Sight) describes the process of finding latitude at noon from the sun, and introduces the concepts of geographic position, zenith distance, and declination. It also briefly introduces the Nautical Almanac, and features three example problems. Here are some additional resources pertaining to this lesson: 1.
