In these days of high-tech communications on land we have multiple options to do anything. However once a boat leaves the main shores, vhf, tv, cell phone signals and wifi hotspots are absent. There are still options to prevent us being totally isolated: we can use either low tech (and expensive) but cranky SSB (single side band - radio) or high tech (expensive) satellite communications. We researched for quite a while, and had hoped to install SSB.
Once we decided what we wanted of our SSB, and had it priced out ($5,000 - $7,000) - we rapidly changed our mind. For now we will use satellite phone minutes (sparingly) when away from land/cell phone signals. Here is Kyle calling home to his mom on a shake down trip off the east coast USA (the Atlantic). This same phone we can hook up to the computer (email, weather, etc), and sometimes it even decides to work!
