SEA Currents: SSV Corwith Cramer

A navigation adventure

Dr. John Huth, Prof. Physics, Harvard University

C-256a Colleague Cruise

DR rhumb line using the traverse board (dotted line) and rhumb line from GPS (solid). Some of the difference may be due to leeway and currents, although the inherent imprecision of the travserse board should be considered. The gray oval corresponds to the region where the Vieques light and the Culabrita lights were simultaneously observable - when I was on bow watch.
