Sailors will argue about which weather app is best, but MyWeather gets high marks from most. It's free and easy to use; it provides forecasts as well as information about current weather conditions. You can see predictions for dinner tonight or as far as ahead as 10 days. If you have a MyWeather.com account, you can sync it with your iPhone app.
MyWeather is boater-friendly. You can adjust its radar images to show expected wind speeds. It will give you weather information for exact map coordinates rather than just cities and towns. It's easy to switch between the location where you are and the one where you're heading so you'll know what to expect.
Of course, boating doesn't begin and end on the water. Keep reading to learn about an app that can help you keep all the details shipshape.
