T&T: a killer good shirt pocket chartplotter

[Paul M. Konnersman]

I have used GPSnavX (same developer as iNavX) on my notebook for 
sometime and Maptech's Offshore Navigator before that. While both of 
these products are missing some features that I would like to see, they 
are both solid applications (at least to the extent that anyone can 
build a solid application on top of MS Windows).

However, I recently installed Raymarine E120 displays with Navionics 
PlatinumPlus charts. Based on this experience I am extremely skeptical 
of any Navionics product recommendation. While some of my disappointment 
is attributable to the Raymarine product (e.g., a "clutter on/clutter 
of" toggle rather than multiple layers of data that can be selected 
independently, inability to use any charts other than Navionics,) the 
Navionics charts, at least for the Bahamas, are pathetic. They appear to 
be based on a collection of old and incomplete data from multiple 
sources compiled with absolutely no editing (e.g., depth contours that 
change abruptly along a straight join, inconsistent color coding of 
depth, use of the same style black line with no labeling to represent 
everything from routes to contours to restricted area boundaries.
