Hi Jim,
Wow! A whole new level of complexity to keep me awake at night! [grin] I've
never heard of anybody degaussing the keel, let alone the trailer.
All I ever did was "swing" the compass according to the instructions in the
owner's manual and to find the constant error, if any. (Swinging the compass
= a process in which you turn both the compass and the boat 180 degrees
together repeatedly... and iteratively adjust the compass to offset the
errors).
If you "swing" the compass, would it really matter if the keel was magnitized
or not? Wouldn't you get a table of constant errors (or find out you had no
constant errors)?
Best,
Judy B.
