Dr David Lewis gave details of traditional navigation in the Pacific in several books - "We, the Navigators" being the most focussed on this. There are also several books on "emergency navigation" which are interesting (the stand-out being the one by David Burch). From memory, there was a pull-out appendix to one edition of "Survive the Savage Sea" which had quite of lot of info, too. As to practical sailing experience, once into ocean swells you can steer minute-by-minute by swell, but over a day you need sun or stars as well. Lewis says that the Pacific navigators found that the best way to sense swells is to stand up and let the swing of your testes tell you...though that could just be a cock-and-bull story.
