5. Slide 5 The Piloting Course A pilot is a mariner who guides ships through dangerous or congested waters, such as harbors or river mouths. Pilots specifically use pilotage techniques relying on nearby visual reference points and local knowledge of tides, swells, currents, depths and shoals that might not be readily identifiable on nautical charts without first hand experience in the waters in question. Why are we worrying about piloting when we don’t fly airplanes?

6. Slide 6 The Piloting Course  Based on Electronic Navigation Know where you are! Emphasis planning & how to use  Aimed at the Recreational boater Must know basics Electronics failure  Open book examination Homework Practice Cruise The art of Navigation with the aid of landmarks and navigation aids (AtoN’s) performed near land (coastal & inland), where navigation is most challenging. website – msi.nga.mil Maritime Safety Information at National Geospatial Intelligence Agency select “Publications”

8. Slide 8 Basic Terms  Course (track) The line that your boat should follow (line of motion) Intended – expected direction Made Good – resultant direction Over Ground – actual direction relative to ground Dead Reckoning – intended course as plotted  Cross Track Error Distance off course (XTE, TKE)  Bearing A horizontal line of direction (line of position) from an observer to a known charted object expressed as an angle from a reference direction, e.g. compass bearing, magnetic bearing, true bearing, relative bearing and ball bearing.

13. Slide 13 Labeling – Planning Step 1. Label waypoints, use unique symbol when not charted AtoN. 2. Draw and measure course lines (length & direction). 3. Qualify course. 4. Label course and reciprocal. 5. Label distance near midpoint. 6. Enter in GPS. Start End (Symbol when not NavAid)

14. Slide 14 Labeling – Underway Step 1. Once underway, label speed for each leg and times for each position. 2. Hourly or when needed, plot GPS position and when possible check with bearing. 3. If GPS is suspect, determine position from bearings or last know good position. 4. Proceed using DR navigation. ?

15. Slide 15 Labeling – DR plotting DR formulas: 60D=ST 1. D = ST / 60 (known speed and time, find distance) 2. S = 60D / T (known distance and time, find speed) 3. T = 60D / S (known distance and speed, find time) S = 6.0 T = 1400 – 1300 = 60min D = 6.0 x 60 / 60 Distance = 6.0nm What is Distance to 1421? What is Distance to 1500? T = 1549 – 1500 = 49min D = 5.3nm S = 60 x 5.3 / 49 SMG = 6.49 = 6.5kn D = 6.2nm S = 5.0kts T = 60 x 6.2 / 5.0 T = 74.4 = 74min ETA = 1549 + 74 = 1703

29. Slide 29 Measuring Long Distances  When the dividers cannot reach from start to destination Select a convenient distance on dividers Start at one end of the course line… Pivot the dividers and count the # of pivots For the final increment, set the dividers to reach the end… Measure the final distance and add the prior increments.

31. 1. Estimate the course (at least to 0- 90, 90-180, etc). 2. Put a pencil or divider tip on one of the course points. 3. Bring the top edge of the plotter around so it goes between the two points. 4. Slide the plotter along the course line until the plotter bulls-eye is on a horizontal or vertical grid line. (Having the pencil or divider on one of the course points makes it easier to slide the plotter while keeping it aligned with the course line.) 5. Read your direction on the compass where it crosses the grid line. Look at the four possible course readings, pick the one that fits your estimate of the course.
