Re: Active Captain & iPad Aarghhhhhh
Technical politics aside, I like eseachart quite a lot. It's cheap and has raster charts, which I enjoy. It has quite a few usability issues, but my main purposes are at route planning at home and activecaptain while underway. With the iPad being poor at best in daylight, I wouldn't use much of the chart plotting underway.
The other thing is that I like using eseachart to look at distant places. I can explore key west, my old stomping grounds on the great lakes and NY harbor, with AC info, without buying more charts.
It doesn't replace more full featured options, but it suits my needs.
