I am the reciprocal of that ? right ?
Or do I have to account for variation from GPS to chart? or is that
a red herring?

You stated that the bearing to the center of the compass rose was
98T, i.e., 98 degrees relative to TRUE north. That means the
bearing from the compass rose looking out to your boat is the
reciprocal, 278T. No allowance for magnetic variation is required
when dealing with (T)rue bearings.

Most GPS units can be setup to give headings and bearings in either
(T)rue or (M)agnetic degrees. Which one you use is mostly a matter
of personal preference but you must be consistent.


Thanks Wayne.
Bottle almost gone but I'm not in charge of a vehicle or on a vessel.
I think I look for traps where there are none when I'm dealing with
examiners.
Part of being educated by Servite Priests (one step below Jesuits in
my opinion when it comes to devious)

Lay the bottle on it's side and give it a spin, the neck will give you
your
true course, so allow for variation.


Hadn't thought of that one. Will try it out. LOL
