I don't know how long this has been around but its pretty cool. You get a little bit more detail of the possible weather where you might be fishing. Instead of the big block area that the text forecasts cover. You just hover over the time you plan on being out and you can see the forecast for wind or wave or almost anything else. It forecasts in 3 hour intervals and give you a 12 hour window that you can advance in 12 hour increments. err something says that its experimental so who knows how accurate it is.
