Bowditch's "The American Practical Navigator" is available online at the 
following website . You can download the entire document at once or a chapter 
at a time. This should get you started without spending any $. This is the 
reference or at least one of the references you should have. It contains a 
wealth of information. There are several other documents at this site which 
may be of interest to you as well.

Enjoy!

Subject: DIY plotting charts


 the books i'm trying to learn from mention that it is
possible to make your own plotting charts on graph or
blank paper, but they don't give any more info...

 it seems like i will need to create a map projection
for the needed lattitude...i'm not sure how i go about
scaling lattitude to longitude at different
lattitudes...is there a formula that does this??

 (i would rather not be dependent on buying and
stowing a bunch of plotting charts)

 thanks, m
