Actually, I find that many in the group are more current and up to
date on many areas of navigation, than I am.

Correct!

And very correct if your talking about
navigation with no external imputs!

What can you use the following bow and beam bearings to find?

22-34, 25-41 , 26&1/2-45, 27-46 , 29-51 , 32-59 .

All numbers are degrees off your bow.

And you travel 5 miles between the bearings.

These are not "bow and beam" bearings. What they are, are a set of
bearings that if you mark the time of each set, the distance run between
them will be the distance off when abeam. (5 mi.)
These come from "Special cases" and include "bow and beam", "doubling
the angle on the bow", "7 tenths rule", "7/3rd rule"

OMG!!! I really don't believe it!


Are you saying that these are figures that are useful to people who are
"mathematically challenged"? ... Like Rednecks???


Are there people out there who are too stupid to take a running fix????

Not sure what you're grumbling about. These are "shortcuts" and means of
estimating a distance you will be off when abeam of an object and are
all part of and ways of, performing a running fix, with quick math
solutions.
They've been used by many sailors for years .... mayhaps you should try
to learn to use them .... add to your knowledge base, as it were.....

I would always double check my calculations anyway(with a proper plot) ....
wouldn't you?

So I wouldn't save any time by using the short cut!!!

It only takes a few seconds to plot a running fix. Why would you bother
with a short cut?

These are proper plots, part of a running fix, with quick estimates to
back up other parts of your plot and calculations, for distance off
estimates.

G The idea is not to save time ....it's to quickly gain some useful
information to back up other aspects of your running fix and especially
useful if you only have the single charted point that you can use to get
your fix.

with a short cut?

It's called "cross checking" or "double checking" ..... most good
navigators use things like this as backup checks on what they are seeing
or doing ..... cost nothing and keeps you busy and focused.
