Pop Jeff ,

Invaluable for boating!

I've used this app for almost 3 years now and rely on it so much I feel guilty I've never provided a review.

I use this mainly for boating in the Upper Chesapeake. Power boating, not sail boating. In the upper bay both wind direction and wind speed play a role in how rough the water will be and I can use this app to show me when the tucking into a certain section of the bay or scooting into the Susquehanna River will find more protected waters at a given time.

I am a sailor, this app really works for me

Spend a little time learning the features and this app will become your first choice for passage planning.

You will find that you can minimize the download file size by selecting the area you are interested in, the parameters you want to see, and the number of days that are of interest.

Really good, easy to use app.

I have used this app for years. When I think about a passage I go here to check the conditions I will encounter. Easy to use. High on my list of really good apps.
