NavCal History
NavCal Inc. was first incorporated as a small business corporation in Valley,
Alabama on 6 June 1988 to design, produce, and sell software and hardware products that
enhanced marine safety for recreational and professional boaters. It has now been
reactivated as NavCal Marine Services LLC with offices at 8016 Ellisville Lane, Knoxville,
Tennessee
Today NavCal primarily operates TRACE 1, our passenger vessel from 300 Neyland
Drive, Knoxville, Tennessee. The dedication to safety that has always driven the
Company (see below) still exists today in our vessel operations. Our commitment to making
recreational and commercial boating safer and more enjoyable for everyone has not
changer in over 20 years. Today's Company employees have a combined record of over 70
years of vessel operations experience in both fresh and salt water on commercial and
recreational vessels. Let us put this experience to work for you. 
NavCal's first product was NCDRLOG a DOS based software program that took
latitude, longitude, course, and speed from a LORAN receiver and generated a Coast Guard
approved Dead Reckoning Log of a vessels course. It would automatically record the
information every 1, 5, 15, 30, or 60 minutes plus allowing the captain to enter comments
whenever he wanted to do so. It stored this data in a file that could be printed but not
changed.
LORAN was slow to respond and not as accurate as the GPS receivers we have today. The updated software is still available today but not being marketed. Lack of time because of commitments to Micro Services Group (see above left, a Microsoft certified computer consulting company) and the Alabama Air National Guard forced the old corporation to become dormant after the 1990 tax year.
