I like the graphs produced by JTides. Here's a link:
http://www.arachnoid.com/JTides/. In addition to plotting the tide and
current predictions, it graphically shows sunrise, sunset, and twilight.
The author requests no money for the program; you'll have to read for
yourself what he wants in return: http://www.arachnoid.com/careware/.

The program is written in Java, so you'll need the Java Runtime Environment
(http://www.java.com/) at the minimum on your computer to make JTides go.

Good luck.

I'm trying to find tide details in graphical form for my local area - any
ideas? (I sail a Waarship 24 and I'm getting sick of running aground)
