If you are coming to these concepts for the first time, Slide 11 will surely have you scratching your head
and eventually cussing someone out. I'm betting that's not the only rough spot in there.
I know you said you didn't want any ASA
stuff, and I agree with you about the textbooks. There are mistakes
in the others, too, including Rousmaniere's "Annapolis Book...etc". The 101 - 104 texts are being replaced, and I haven't seen the new ones. But my wife and I took the ASA navigation course (105?) and thought it did an excellent job of presenting the basics. There are mistakes
there, too, especially in the problems section (doesn't anyone ever check these things?) but the concepts are very clear.
We took it as a home-study course with test and certification
at an ASA school
for, IIRC, $100. If you're not interested in certification
, the book alone will cost around $70. Not cheap
, but we thought it did a good job. The book is Mike Pyzel's "Coastal Navigation - Advanced Cruising Techniques" and is available (I think) only from ASA. Good luck, and please let us know what you find.
