I want to go faster than other boats, at this point dinghies and small keel boats. I know the very basics (try to get all tell tales flying, try to keep the luff of the spinnaker right on the edge of curling). Now I want to learn how to manipulate everything (jib cars, traveler, boom vang, outhaul, etc) to get the sails working together as well as possible, and I want to learn the science behind everything as well.
Has anyone had any experience with an online course or resource that not only teaches you what you should be doing to trim sails, but also the reasons why all the trim adjustments matter?
I'm looking at NauticEd, I like how they have animations of how different adjustments change airflow. Just not sure if they're good or if anyone knows of something better.
