He was a Professor who taught Navigation, marine focused Wireless Communications, and Naval History. He was also one of the best Compass Adjusters on the West Coast. He died of cancer in 1993. His name was Robert E. Larson. I was just a baby when I first met the sea Twas my father, grandfather, the Skipper, and me. The salty sea splashed me, I started to cry. Grandfather smiled, then laughed and asked why "That means the sea likes you; she gave you a kiss. So blow a kiss back and say 'Thanks' for the mist." Now, all these years later, on the South Salish Sea, With memories of father, grandfather, and me, I stand on the deck of the Samish ferry Getting salty sea kisses from my Lady, the sea.

That's called a deviation chart. It's easy for electronics to take a reading, apply the deviation and obtain a true result. For people, that extra step is a pain in the butt, so correcting the sensor is preferable.

That was absolutely fascinating- a far more complicated set-up than I had previously thought. I've searched my now-fading memory, but I do not remember magnetic compasses on any of the ships upon which I sailed, although I have seen these binnacles elsewhere. I remember the gyrocompasses. Iron ore from Canada was a frequent cargo, so I imagine that prior compensation for that would be very difficult for magnetic compasses.

Great explanation of “Swinging the Compass”. The same kinds of problems occur on airplanes as well. We have to record the errors that remain on a small card that is kept with the compass for our Cessna 172. We also want to take into consideration that vertical component that will cause a compass card to dip as one gets closer to one of the poles. The dipping of the card can actually cause the compass card to get stuck and not spin toward its new reading in some cases.

Damn. Ingenious and yet so simple. So 'simple' I wouldn't have thought it was a problem until I ran into a reef. Institutional knowledge is fantastic (and humbling). Thanks so much for sharing!

Wow, I knew the approximate function of a binacle, but no idea how it actually did the compensation. That's a fascinating technology, and much more complex than I imagined.

I had a magnetic compass in my car many years ago and the effects of chassis magnetism were significant. It was educational to watch the compass needle jump when I hit the starter and 500 amps flowed thru the battery cable and the motor's windings below the transmission.
