...you don't need a (relatively) expensive single sideband set and radio-nerd tendencies to pick up weather data offshore where you live? That is pretty great if so. Would that there were more of it.
This is stuff like fishing recommendations by species, sea surface heights, temperature contors, 30m deep temperature condors, plankton concentrations, weather radar, storm tracks, wave heights, and more and then integrated into common Garmin, Raymarine, Lowrance, Simrad, and other equipment that many boats would already have. All of that data constantly updated and refreshed live even when you're miles out to sea and can't pick up common line of sight style transmissions.
Its not just a METAR weather report from an airport kinda near the shore.
