Six of us are sailing a 38 foot from Wellington New Zealand down to Fiordland, 500 nautical miles one way. While in transit we will have an Iridium phone for obtaining weather data. The phone will allow us to send and receive Text messages. A little experimenting on shore we have discovered that Iridium sends text messages as an email. Therefore using an email forwarding service would allow us to send one update and have it forwarded onto all our friends and family saving us the difficulty of sending 30 or so messages in a rocking boat.
