Check out this new app. You put in your starting point and your ending point and it plots the route for you, taking into account wind and currents. It's in beta testing and they are looking for input. There are some known bugs. Mobile apps for android and iOS are already in development.

I tried to look at it but was asked for my email address even before I saw a list of features and any benefits the program might have. I am curious how the program knows the polar specs for a boat and what the upload of grib info looks like but won't trade my email address to find out. Sorry.
