"Using clues he gleaned from the Icelandic Sagas, his experience as a professional navigator, and from his voyages on "Borgunknarren"—a 60' Viking ship replica—Leif K. Karlsen reveals the secrets of Viking navigation. Karlsen has done extensive research on the Viking "sunstone" and "horizon board" and explains how they work. This is an interesting, valuable, and educational contribution to the understanding of the Vikings' success as navigators and seamen."
