Here is another lovely example of a program playing the role of Captain while you are merely a deckhand to the computer overlord. Hurricane Chris is looming to the NW of the boat and the computer is suggesting that the GREEN boat should head up into the hurricane and sail on its navigable semicircle.
Why? Because the hurricane is predicted to move straight and this would give you favorable winds to sail quickly.
What if the hurricane turns Easterly? Now what?
Weather routing software is nice to confirm what you have already decided is prudent and best. It can be used to run out theories in your head, but it should not by any means be the Captain of the ship. The software runs under the premise that the forecast is correct and as we all know, the forecast is never correct. This means that the suggested route is not going to be as expected!
If you still feel the need to have a program tell you where to go, don’t go to sea yet. Take some classes on weather and weather routing, read some books, and learn the material yourself. First, so that you can judge if the electronic information is prudent, and second, so that you can still navigate the weather should your electronic leader die at sea.
