Terrestrial Navigation Introduction

This was designed to help prepare yourself to pass the Coast Guard exam on Terrestrial Navigation, or if you are just interested in learning about terrestrial navigation. I will try and make it as easy as possible and easy to understand. I will give you step by step instructions for doing all these problems. You will need Plotting Sheets # 5089 or 5090, Dividers, Parallel Rules, Triangles, Calculator, reprints from Light List and Coast Pilot 1993, and Tide and Current Tables 1983.

Terrestrial Navigation for 3rd and 2nd Mate, Master / Mate 200 - 1600 Ton Inspected Vessels Near Coastal / Oceans. I have tried to design it for the applicant testing for the math / celestial test (5 /10 question - 90%) required by the Coast Guard. I will cover Compass Problems, Finding Deviation or Gyro Error, Distance Off Problems, Radar Plotting, Tide and Current Problems, Fuel Consumption, and Speed by Wheel Calculations.

Master or Mate 25 - 100 Ton - Inland or Near Coastal. I will cover the required USCG subject areas such as: Rules of the Road, Chart Navigation which covers Nautical Publications, Chart Reading, Compass, Time, Speed and Distance Calculations, ETA’s, Course Made Good / Speed Made Good, Types of Fixes, Finding the Set and Drift of the Current, Checking the Deviation Table on a Range, Finding a Course to Steer with a Known Set and Drift, and Computing the Height of the Tide and Velocity of the Tidal Current. I also will cover Navigation General and the related information used with chart work.
This site will be updated and under construction.
