Errata for
Navigation Workbook 18465 Tr, 8th printing
| 3 | The Chapter 2 notes recommend reading the introduction to the Light Lisst, but looking at the lates available in Jan 2026, we get a note that they are working on an update. So for now you can read an archived version at this link Light List Front Matter. All traditional paper charts made by NOAA were discontinued at the end of 2024, and with that they discontinued all the Chart Catalogs. So Exercise 2-20 and 2-21 are no longer valid. Here are new versions to work on: 2-20. Use starpath.com/getcharts item 1.1 to learn: (A) what Electronic Navigational Chart (ENC) numbers cover Neah Bay at the western end of the Strait of Juan de Fuca, on the US side? Meaning the ones with the largest scales. And (B) what is the chart scale for the charts? Answers: (A) US5WA2YC, US5WA2XC; (B) 1:12,000. Note: Beside using /getcharts, you can use qtVlm with Training Mode installed. Just search on Neah Bay, then go there and you will see the two charts. Alternatively, with qtVlm, go to Neah Bay, then draw a box around the full Bay, right click and load the NOAA Catalog, and it will show all charts that cover that box, organized by scale. This is a super convenient tool in qtVlm that applies to anywhere in US waters. 2-21. Use www.starpath.com/getcharts, item 1.5 to zoom and view the chart from 2-20 to answer this questions: Zoom in till you see the breakwater and docks of the Neah Bay Marina and then answer (A) How many lights are on the break water? (B) What are their colors? (C) Use the measure tool to determine the distance between the two on the longest section of the breakwater? A answers: (A) 3; (B) G, Y,Y (C) 0.18 nmi. |
| 4 | 2-26(d) Change "5 mi due east of" to "about 5 miles SE of." |
| 4 | Figure 2-25 has several numbers mixed up. The 44 should be 2.1 and the 56.4 should be 54.1 |
| 6 | 3-10. Reference to using the Light List means compare the latest version of the Light List with what is on our training chart from 1998. |
| 13 | 6-1. Change distance to light from 4.2 nmi to 4.4 nmi |
| 22 | New exercise 9-14:
9-14. A running fix with course changes and in a current. Here is the logbook. We are navigating by log and compass, so there is no speed recorded here, but generally that would be included in the logbook. We use 20.0ÂșE for all 18465Tr work. Part A. Find your position at log 56.8 assuming no current. |
| 33, 94 | 11-2. Question and answer: We get the chart number right on our training chart, printed in Port Angeles Bay, but that does not tell us the scale of that chart. The answer was 18468, which is printed right on 18465tr at Port Angeles Bay. But that did not tell us its scale (1:10,000, a large scale chart). Our present answer says scale can be found in the Chart Catalog or Coast Pilot. But this is no longer true because this chart and all other traditional printed charts no longer exist. Going forward for your own navigation, the only paper charts that will be available are called NOAA custom charts (NCC) and unfortunately these charts will not have any printed hints about what chart to use for more detail (larger scale) in any location. We will have to learn that from the NCC creation tool, that lets us zoom in on any region to see what is available and then we make or by one at the largest possible scale. See www.starpath.com/NCC which has video links to the process. |
| 78 | 3-9. Answer, change [CP page 189] to [CP 190] 3-10. Answer. LL data given are what they were from about 2000 to 2025. These two lights got updated nominal ranges shortly after the chart was frozen in 1998. For this exercise the right answer uses the charted ranges, but in practice after 2024 the chart (ENC) will always have the latest correct value. |
| 78 | 3-15. Clarify source: 9 ft, see paragraph [CP 193] in the Coast Pilot |
| 82 | 5-18. A more precise answer to 5-18(a) is 48° 22.73'N, 123° 19.07' W. |
| 83 | 6-1. A more precise answer to 6-1(a) is 48° 22.53'N, 123° 18.58' W. |
| 85 | 8-8 (C) need tide of >3ft available from 0600 to 2300 PDT. |
| 88 | 8-16 solution: add this link to a note on NOAA current graphs |
| 89 | 9-5 answer has a typo 13V = 13° |
| 90 | Top right table are the answers to 9-11, not 9-12 |
| 91 | Part A. No current fix = 48.287,-123.585; Part B. With current fix = 48.288,-123.579 Plot of the solution. |
