Navtex.

SSB to laptop, free software. Works great.

You can dig into the NWS web site and find the same text forecasts and use saildocs to retrieve them using e-mail over your sat phone, but Navtex is FREE and you don't have to burn sat phone minutes, or even have a phone.

sail fast and eat well, dave
