Total sailing line from an experimental precision mapping of Wreck 1, Lundeborg (blue double circle) (see Figure 8), for which only an approximate position was known. Two other wreck features were observed (blue single circles); the westernmost is most likely Wreck 2, Lundeborg, which represents one half of another medieval ship; the other may represent the “missing” half of Wreck 2 or a third wreck. The sailing pattern represents approximately 10 hours of sailing time at the location. This illustration has been produced by Grøn and Boldreel.
