  • Through the Reefs in the Bahamas

    Explore shallow reef-strewn waters of the Bahamas. We run up on the beach in the far-out Bahamian Islands. Travelling the Far-Out Islands of the Bahamas there are often no other boats around for days. This trip was in the late spring, and we visited islands where very few boats travel. Our boat is very shallow with a swinging keel - our draft is just 3 feet with the keel up. Using the Explorer charts for the Bahamas we visited the Crooked and Acklins group, then sailed on to the Exumas. Check out our boat here... http://www.distantshores.ca/about-us/the-boats/southerly-42/ All 130 half hour episodes of the Distant Shores TV show are also available on DVD and download at: http://www.distantshores.ca/sailingdv...

  • Nautical mile

    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.

  • 34 fix position distances and compass bearings distances and compass bearings 1

    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...

  • Calculating Distance with Latitude

    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.

It remains in use worldwide because of its convenience when working with charts. Most nautical charts use the Mercator projection, whose scale varies by about a factor of 6 from the equator to 80° latitude, so charts covering large areas cannot use a single linear scale. The nautical mile is nearly equal to a minute of latitude on a chart, so a distance measured with a chart divider can be roughly converted to nautical miles using the chart's latitude scale. The nautical mile is commonly used in international law and treaties, especially regarding the limits of territorial waters.

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 miles on the latitude scale which is closest to the present position and which runs along the sides of the chart. Apply this span, placing one leg of the dividers at point A, and draw a semicircle near the course line. Now span a distance of 2.8 nautical miles and apply this span, placing one leg of the dividers at point B, and draw a second semicircle intersecting the first semicircle and near the course line. The point where the two semicircles intersect is the fix position at 0930 hours.
