Do not know anything about HO208.  Any chance of filling in yet another gap
in my education?


I believe HO-208 was designed by Lichter? And HO-211 was designed by Ageton.
HO-208 uses the same basic format as does HO-211 and in reality is most
likely an older method than HO-211. It is a more convoluted system to use
than is HO-211. I will provide a link that gives downloadable worksheets and
rules to HO-208 and HO-211 and may provide the data pages for HO-211 also.
HO-211 is not hard to use or very slow to reduce sights for LOPs at all. If
you learned the rules to use the HO-214,229 or 249 reduction formats and
became proficient in using them then HO-211 can be learned and used in about
the same amount of time. Just as in using the HO-229 or 249 formats to get
fast,dependable results one must practice using them to do so. It is just a
different format to accomplish the same thing. Both systems(208 + 211)are
based to reduce sights by using t(MA)instead of the way the newer tabulation
methods,except HO-214,are formatted. What is really nice about the HO-211
system is a person only needs the HO-211 data book (35 pgs) and a NA to
reduce sights from any band of latitude. One can forget about carrying all
the volumes of the newer systems onboard. And both are just as "accurate" as
are the newer tabulation methods of sight reduction "in the real world".
When I was 1st taught reduction HO-208 was used by the mariners who taught
me. When I sat for my 1st CG exam for CN the method they used during testing
was HO-214 so I had to learn that method even though by that time HO-229 was
used almost exclusively in the fleet. So I also had to learn HO-229 after I
passed the exam and went back to work in the fleet. Yes, I've used them all
and each method has its strong and weak points to use but each gets the
