The DECCA had our fix as being 10NM inland. I have never trusted ENS since and still to this day insist that crew members pass a basic navigation test before being allowed on board :) many people in pleasure craft these days think there iPhone or Android Tablet have superseded the need for basic navigation and radio. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
