Consider a Delorme Inreach. Uses the Iridium network. But since it doesn't keep a constant connection like a satphone or GO, it seems to be much less twitchy about antenna
. I just leave mine on the chart table below. It works fine through the fiberglass
overhead. Sometimes there's a 30-60 second delay sending a message while it waits for a satelite but nothing remotely like the connection problems of satphones or SSB/Ham.
They have recently released a marine weather forecast
service. Certainly not equal to a GRIB but it's only $1 for a forecast
DeLorme inReach - Two-way satellite text messaging, tracking and SOS anywhere in the world
I also have a friend ashore who I can email
with the Inreach who will send me back a weather forecast off the Internet
. He just abbreviates the report to fit in one or two 160 character messages.
