Do you know the name of the book?

Thanks for your help. This is all Greek to me, so clearly a little education is in order.

For those of you who think I've lost my mind. Please understand that it can be miserably hot and sticky here in the South and all my camping questions really relate to cruising on my Tiki in the Keys. Unfortunately, it is sometimes necessary to stop off at the edge of the Everglades. Camping in the 'glades must be experienced to be understood! <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />

A more basic problem has to do with power for navigation lights and electronics. It takes a lot of battteries to cruise for a week, even for a Garmin Geko!
