I have spent a fair amount of time boating on the Big Water (Michigan, Huron, & Superior). The marine VHF weather channels are geared specifically towards boaters. It is similar to the All Hazard Radio but repeats marine weather observations, forecasts, current conditions, air temp, wave height, winds, and also climate. I would never be on the water without it.
Very cool you picked up the EC. We picked it up when in Georgian Bay and North Channel, it is very similar to US marine weather.
