As a Professional navigator and weather router for racing yachts, Digital Atmosphere is the tool I was looking for to gain an edge over the competition.  We have had the ability to display model data (limited to surface and 50KPa fields) for some time with our navigation software which has led to the unsafe practice of relying solely on model data.  With Digital Atmosphere I have access to the most current observations worldwide in one simple download.  Now, thanks to DA, while others are blindly following the model I am fine tuning my strategy with real data.   Eric Holden Holden Met Services
