The big picture: If you want onboard Internet for work, pleasure, or actual boating-related information-or, like many of us, all of the above-2009 is a very good year.

And thanks to improving nonmarine mobile technologies, namely WiFi and cellular data, more and more nearshore boaters can get online reasonably well using just the devices and services they already take on the road. But for the areas in between, both in terms of location and budget, online strategies remain a confusing mélange of conventional and marine-specific possibilities. Let me explain with specifics.
