Sorry for the bandwidth, but I thought this would be a good time to restate
some Silicon Sea usage to any newcomers.
John's answers all correct. When the problem answers are posted you will
see slight differences between the answers. This comes from the use of
different methods used. As long as your answer is within the circle of
error the answer is correct. The error is your visible horizon. On Silicon
Sea that works out to 3.3 mi using United States data - Dist to Horizon =
1.17 x SQRT HE(height of eye). If your system uses another standard don't
worry about it, use it. The answer is still correct. That's the way
practical navigation at sea works. In fact when I cruise I round all Lat &
Lon to the nearest whole degree.
Because of minimal information on the Mediterranean I am ignoring cruising
details, including the Oil Platforms we will be passing shortly. Because I
don't want my Grandson to inherit this project I will be making big jumps
in passages after the next couple of problems. The Suez Canal transit will
be a worlds record.
  Cheers,
