Author Topic: Electronic Charts

In doing lesson 1, for chapters 1,2,3, - I noticed that the electronic chart does not match the questions. For example on the electronic chart 18465, questions 1-2 and 1-3 refer to buoy Y "R" on the chart. However, it is buoy YB "R."

Question 1-5 and 1-6: There is no buoy R "4" listed on the electronic chart 18465. Please advise, I also have a copy of the paper chart with the buoys marked. Are the echarts not to be used to answer the questions? Fred

Thanks for pointing this out. I think this is discussed in several places in the discussion groups. There is some inconsisteny in the charts.


also try searching both discussion forums on "buoy R4"


As for question answers, you can use either chart for most of the questions. and you may want to just add add a mark on the electronic chart where you need buoys... actually a good exercise as this might come up underway.
