How to measure distance on a nautical chart.
How to measure distance on a chart and work out the time it will take to travel. Nautical navigation. Watersports training
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.
A slick way to do echart navigation on google earth, as well as viewing all NOAA charts and even a fast way to download the RNC versions. Main link at NOAA describing the process http://www.nauticalcharts.noaa.gov/csdl/seamlessraster.html Direct link to the Google Earth file we need http://nosimagery.noaa.gov/rnc/noaa_rncs.kmz
Northern California has a storied, 500-year history of sailing. But despite this rich heritage, scientists and boat designers continue to learn more each day about what makes a sail boat move. Contrary to what you might expect, the physics of sailing still present some mysteries to modern sailors.
We talk about a vehicle "log" and a "rate of knots", but where did the terms come from? As Rob explains, they date back to the equipment on sailing ships.
Calculate the distance between two cities.
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.
TabletClass.com - http://www.tabletclass.com Math. This video explains the basics of how math is used in celestial navigation. When people first started to navigate by stars a massive explosion in trade and culture developed. Celestial navigation requires the use of a sextant, clock and nautical table but most importantly it requires mathematics.
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.

What is NAUTICAL MILE? What does NAUTICAL MILE mean? NAUTICAL MILE meaning - NAUTICAL MILE definition -NAUTICAL MILE length - NAUTICAL MILE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. 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. Graphic scale from a Mercator projection world map, showing the change with latitude It is a non-SI unit (although accepted for use in the International System of Unit...
In this tutorial, I will demonstrate how to distance between Kilometers and Statute or Nautical miles using the Jeppesen E6B mechanical flight computer. If you find any mistakes, please point them out. Feel free to leave questions, comments, and feedback below. Good luck on your journey to becoming a pilot!
During this lightwind session I was giving the nautical mile distance a shot and reached 30,58kn in ~25kn of wind with a 90l Starboard Isonic and a 6.0m² Severne Overdrive 2010 with a 29" fin. The session was done as part of the German Speed King, check out GPS-speedsurfing.com for more information. Shots were taken 100% on the GoPro Hero 3+ Silver, check my channel for more windsurf related videos if you enjoyed the video.
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
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.

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.
Learn how to plot a course per standard compass on a paper nautical chart from the experts at U.S. Captains Training. Captain Neil Smith demonstrates finding points using the longitude and latitude scales, taking proper measurement on the compass rose with parallel rules, and converting degrees True to Compass. Practice along on a 1983 Block Island Sound chart to prepare for your upcoming U.S. Captains Training class and test.
