NavPac

The NavPac series is intended to increase the efficiency and accuracy of competent
navigators.  It is NOT a subsitute for a comprehensive Boating Course.  If you have 
not already done so, PennSoft HIGHLY RECOMMENDS that you atleast take one of the
many Boating Courses offered by the United States Power Squadron, The Coast Guard
Reserve, and many states.  If you have difficulty locating a course in your area, try
contacting Boat U.S.  They are advertized in most boating magazines and are widely
known to the boating fraternity.  Call their 800 number.  They will direct you to the
next available course.  They will even pass your name and phone number to the local
organization if you wish.  Anyone who operates a boat of any size, dingy or yatch,
without proper training is a hazard to themselves, their guests, and other boaters.

PennSoft assumes NO LIABILITY for the incorrect or improper use of these programs.
PennSoft assumes NO LIABILITY for the accuracy of these programs.  Every experienced
navigator knows that they must be prepared to take over all functions MANUALLY at ALL
TIMES.  Electronic equipment and water are definitely incompatible.  In other words,
PennSoft stands by the ancient saying, "When Sailing, Critical Equipment FAILS at the
most Critical Time".

The TVMDC program converts courses and bearings from True to Compass and from
Compass to True.  It use is simplicity itself.  Simply enter the numbers you know.  The
program will calculate unknown values and complete the table.  Be sure to enter East
or West for Variation and Deviation.  If the program is not calculating the variables you
want, place a question mark "?" in the field you want calculated.  This will force TVMDC
to calculate the designated variable.
