Awesome, awesome, awesome.... Need we say more! This IS the must have App for sailors with an iPhone. I found several weather stations within just a few miles of our marina (Tampa, FL) within minutes of installing this on my iPhone 3G. It has a very useful/intuitive layout and is worth every bit of $1.99. This app can be found in the iTunes store. There is a free version that is add supported, but go ahead and splurge for the two bucks... trust us!
