Cecil Green, Gulf of Thailand -
The above picturess are curtesy of John Wishney. One picture
shows John and the Green standing on a shoal in the Gulf of
Thailand, circa 1973.
The bridge fathometer had been miscalibrated in Singapore. Some
basic math on the Geonav display made that evident, but no one
believed it. At about 3am the inevitabel happened and the Green
ran aground. Not a great deal of damage was done other than the
Geonav transducer was smashed through its seals, thereby flooding
the hold which John had to dive into and close the leak.
Maybe some folks will recognize themselves in the photos.
