There Is A Lot Of Movement On Board A Ship At Sea. What Happens To The Compass Then?

To stop the needle and card from swinging wildly on board ship, even early compasses were gimbal mounted in a square box by an attachment with swivelling rings. This means that the compass is hung in a way that makes it unaffected by the movement of the ship on the sea. The remains of one such compass, housed in a special stand called a binnacle, was found in the wreck of King Henry VIII's flagship, the Mary Rose, which sank in 1546. At that time, the compass would have been lit at night by a candle.


By the 19th century, the ships compass had become the familiar large, gimbal mounted instrument, enclosed in a binnacle with its own light.
