Celestial Navigation
Knowledge of celestial navigation is required for any license endorsed for
an oceans route; meaning more than 200 nautical miles from shore.
USCG courses in Celestial Navigation are designed to meet exam
requirements and rarely contain any practical sextant use. These courses
focus on use of the Nautical Almanac, sight reduction tables and position
fixing using running fixes on universal plot sheets. For licenses over 200
tons the course should include instruction in the sailings, time zones,
route planning and star identification.
The course length indicated is considered to me the minimum amount of
time required to complete the course. Few students are capable of
completing a celestial navigation course successfully in the minimum time
frame unless they have spent considerable time preparing or have
previous experience with the subject material. To be successful in any
celestial navigation course students should:
- Have good basic math skills for addition, subtraction, multiplication
and division.
- Have the ability to read and interpolate numbers from different
tables.
- Have good plotting skills and understand concepts for DR plotting
and running fixes.
- Have the ability to take good notes and keep information in a neat
and orderly manner.
- Have an understanding of the basic concepts and terminology used
in celestial navigation.
The best study material for any Celestial Navigation course is to get a
copy of PUB 9 - American Practical Navigator (BOWDITCH) and the
version of the Nautical Almanac used in the USCG exam questions. Both
of these references can be downloaded from the Internet for free.

government publications regarding marine navigation can be
downloaded for free, including the American Practical Navigator.

Deck Exam Questions page. Select PUBLICATIONS from the menu
and the "Nautical Almanac - For Deck Examination Purposes Only"
can be downloaded for free.
Columbia Pacific Maritime Courses
All Celestial Navigation courses taught at Columbia Pacific Maritime are self-
paced courses; meaning the student completes workbook lessons at their
own pace under the guidance of a qualified instructor. Basic math skills
and the ability to read, understand, and follow instructions and example
problems are required for successful completion of these courses.
Celestial Navigation (200 TONS)
Any applicant who has successfully completed your 60-hour Celestial
Navigation (200 Tons) course and who presents your Certificate of

Any applicant who has successfully completed your 80-hour Celestial
Navigation course will either satisfy the celestial navigation problems
examination requirements to increase the scope of a license as Mate
500/1600 Gross Tons from Near Coastal to Oceans (exam module

requirements to increase the scope of a license as Master 500/1600
Gross Tons from Near Coastal to Oceans (exam module 206XX). This
course will not satisfy the Navigation General or Deck & Navigation
