Swinging the Compass on a [Tiny] Containership

Показать описание

Simplified description of swinging a compass on a ship. Everything with a magnetic compass has to do this to maintain accuracy, so it's pretty important to know.

Thanks for sharing, it's fun for us on land to learn a little bit about the various tasks that keep our nautical friends safe and employed!

Very nice episode on the importance of verifying the magnetic compass corrections on the “compass bridge”. I bet you have a whole lot of retired sailors with ball cap envy now that you have shown us your new cover on monkey island! Carry on!

Good lesson for those who’ve never been there….you always explain so everyone can understand. Most people don’t know how few crew is on the smaller ships . And the responsibility s are shared …good sailing Maddie, all my time was spent in the other half of the globe….haha.keep us informed when you can…….

Thanks for the compass lesson and good to know you won't go astray! Always enjoy your videos.

clearly a modicum of joy in the rain.
Yay

I loved doing an amplitude at sunset to check gyro error.

I did some work on the USN Mercy the white decks were brutal on the eyes if you didn’t have our sunglasses.

All Matson ships should be blessing their vessels the Hawaiian way:

1. Fill a small bowl with fresh water (salt water is used for cleansing).
2. Obtain a long leaf (ti leaf if possible, fern leaf is next best, but any leaf will do).
3. Hang some kind of lei over the gangway or entrance to the boat (flowers or leaves, real or symbolic. In Hawaii maile vine would be used if possible).
4. Announce to all present the purpose of the blessing.
5. Cut or undo the lei (this is like cutting the navel cord).
6. Dip the leaf in the bowl and sprinkle all areas of the boat while giving some sort of blessing ("May this boat be blessed with love, power, and success" (in Hawaiian: E ho'omaika'i i keia wa'a me ke aloha, me ka mana, me ka pono).
7. Have everyone present hold hands on or near the boat and give a personal blessing for the boat and the owners/operators.
8. End the blessing with a song, a chant, or a simple "Thank you" and a hug.
9. Finish with a luau, a "pupu" (snack) party, or some kind of refreshments.

I understand the magnetic compass will work when power is out unlike the primary compass that needs electricity. But to what end? If the ship loses power it won't have propulsion nor rudder control.

I learned something new! I had to use Google’s “bard” AI to learn more about deviation card, local magnetic anomalies, etc. One of my favorite books? Longitude by Dava Sobel. A short read but very interesting.

Great show again. When you "Swing the magnetic compass" you are recording the error right? You are not adjusting the magnetic compass with little magnets, Right? I have seen small magnets used on small boats. Are ships Degaussed any more?

Just curious if you use GPS to validate everything to compensate for N/S deviation?

I remember when we used Dr and set and drift...

How will the earth's geomagnetic excursion of the poles affect your magnetic compass readings? The magnetic poles started moving back in 1850 and the speed of the movement has been increasing drastically. The magnetic poles have shifted further in the past 23 years than they had in the previous 150 years. Will you have to swing the compass more than once a year?
