I don’t have to go topside and turn on weather channel or fire up PC or TV… I just open this app and my nearshore weather and forecast is there and in a very pleasing format. I love it!

Able to find all my local and regional marine forecasts. Also great for planning longer voyages to waters outside my local area.
