Excellent advise. Thanks

On warships we would at least once a year hit the compass course and swing the ships magnetic compass

Brilliant. Thanks Tom.

Tom, it is not evident from the video, which direction to point the HB compass when comparing with boat one. From video it seems to be pointed to castle again, but it doesn´t make a sense of course.

Thank you for a nice video again How you make sure when compearing the compasses that your bearing compass is exactly on bow direction

Stunning! I never thought about it but to my excuse I am not a boater.
Is there no way to calibrate the compass to compensate for the misseeading?
Or is the deviation so inhomogeneous that you cant do a compensation and need the table for every quadrant as it is a diffrent reading?
Thanks for the education, great job to get my brain working on this .

Your method is OK if you have a crew member to run the hand bearing compass, and if it can truly be guaranteed that somewhere on your boat will be free of deviation, and that the hand bearing compass does not suffer from lag due to internal friction.
As a solo sailor I use a combination of known transits (as published or plotted from paper charts) and GPS to satisfy myself that the main steering compass is within 2 or 3 degrees – which is close enough, given the unknown effects of drift etc.
In the narrower reaches of the river where I sometimes sail I have seen external magnetic influences such as ships, tank installations and overhead power lines cause compass errors, and of course the effects of electrical equipment must be considered. If you sail at night there’s no point in swinging the compass by day with internal compass lighting off, but on the other hand if it’s swung with lighting on, the deviation card is only valid for that condition.

You don't keep going 60miles without rereading so no yoi dont accumulate 60 miles of 5 degrees off.

Brilliantly explained – and I've learned a new word: chunkling 🙂
