It will be. I'm sorry. I thought I was more clear.

Would you recommend Calder's book as a good source to learn not just how to read a chart but how to figure course, set, drift, accounting for currents, tides, etc. and all those other things that I should know but don't yet know that I should know?
I don't remember offhand if it teaches you how to figure out your course with current set and drift. I think I left my copy on the boat in my nav bag. Boater's Bowditch has a brief explanation.
