    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...

Distances at sea are always measured in nautical miles. One degree of latitude is equal to 60 minutes, and one minute is equal to sixty seconds. One minute of latitude is equal of 1 nautical mile, 1852 meters or 6076.11 feet Before you measure any distance, look at the scale of your chart. In this example the scale is in degrees and minutes. To measure a distance, always use the latitude scale, located in the same parallel from where you want to measure. Do not use the longitude scale.

Knowing the speed, the next step is to determine the distance that the vessel sailed from 0900 to 0930. For that we use the formula: D is equal to S times T divided by 60, where D is the distance in nautical miles, S is the boat speed, and T is the time in minutes.

Use the dividers and span a distance of 10.5 miles on the latitude scale which is closest to point A. Apply this span on your course, placing one leg of the dividers at point A and the other leg on the course, marking the new position B. We can see that the distance from A to B is 10.5 nautical miles.

You can determine the distance knowing the height and the vertical sextant angle of the lighthouse. Let's assume you sail near the coast and, looking on your nautical chart, you spot the lighthouse A. Among the characteristics of the lighthouse, you read that it has a charted height of 103 meters or 338 feet. This is the height above mean high water spring tide. After calculating the height of tide at that time, the corrected height of the lighthouse is 105 meters or 345 feet. Use the sextant and measure the vertical angle of the lighthouse. Let's assume, after applying the index error, that the vertical angle is 2 degrees and 30 minutes. Knowing the corrected height and the corrected v...

    How do you measure a distance that is longer that the span of your dividers? Assume that you are sailing from point A to point B. The true course is 110°, and you want to know how many nautical miles it is from A to B. However, the distance to be measured is greater than the divider's span. Use the dividers and span a distance of 10 miles on the latitude scale which is closest to point A and B. Walk the dividers along the course as many times as needed until you get close to point B, and mark the last point as point X. In our case we need to walk the dividers three times. That makes 3 times 10 miles, equalling 30 miles. Now measure the distance from point X to point B and apply this span on the latitude scale which is closest to point B. On the scale you find that in this case the dist...

Knowing the speed, the next step is to determine the distance that the vessel sailed from 0900 to 0930. For that we use the formula: D is equal to S times T divided by 60, where D is the distance in nautical miles, S is the boat speed, and T is the time in minutes. In our case: 8 knots times 30 minutes divided by 60 equals 4 nautical miles. Using the dividers, we span a distance of 4 miles on the latitude scale which is closest to the course line, and which runs along the sides of the chart. We applied this span on our course, placing one leg of the dividers on the 0900 LOP intercepting the course and the other leg on the course line. Using the parallel ruler we transfer the 0900 LOP to the blue mark. As we notice, the two LOPs intercept at the point RF. This is our Running Fix position.

A Fix can also be obtained by combining a compass bearing and a distance of the same lighthouse. You can determine the distance knowing the height and the vertical sextant angle of the lighthouse. Let's assume you sail near the coast and, looking on your nautical chart, you spot the lighthouse A. Among the characteristics of the lighthouse, you read that it has a charted height of 103 meters or 338 feet. This is the height above mean high water spring tide. After calculating the height of tide at that time, the corrected height of the lighthouse is 105 meters or 345 feet. Use the sextant and measure the vertical angle of the lighthouse. Let's assume, after applying the index error, that the vertical angle is 2 degrees and 30 minutes. Knowing the corrected height and the corrected vertical sextant angle of the lighthouse, calculate the distance, using the formula: D is equal to h times 0.565, divided by v, where D is the Distance in nautical miles, h is the Height of the Lighthouse in feet, and v is the Vertical sextant angle in minutes. In our case, 345 feet times 0.565 divided by 150 equals 1.3 nautical miles.

How do you measure a distance that is longer that the span of your dividers? Assume that you are sailing from point A to point B. The true course is 110°, and you want to know how many nautical miles it is from A to B. However, the distance to be measured is greater than the divider's span. Use the dividers and span a distance of 10 miles on the latitude scale which is closest to point A and B. Walk the dividers along the course as many times as needed until you get close to point B, and mark the last point as point X. In our case we need to walk the dividers three times. That makes 3 times 10 miles, equalling 30 miles. Now measure the distance from point X to point B and apply this span on the latitude scale which is closest to point B. On the scale you find that in this case the distance is 4 minutes or 4 nautical miles. So the distance from A to B is 34 nautical miles; 30 miles plus 4 miles.

The Office of Naval Research (ONR) demonstrates the Navy's electromagnetic railgun initial rep-rate fires of multi-shot salvos at the Naval Surface Warfare Center Dahlgren Division. The revolutionary railgun relies on a massive electrical pulse, rather than gunpowder or other chemical propellants, to launch projectiles at distances over 100 nautical miles – and at speeds that exceed Mach 6.
