There is a program called the Visual Passage Planner that I have used to figure out best routes. It contains the stats for wind, current, weather from the pilot charts and figures out best routes based upon the characteristics of your boat and your preference for speed or comfort. It is being used both by ocean sailboat racers and commercial freighters and tankers. It does not work very smoothly, but it does work pretty well for offshore legs.
