What is the difference between compass and binnacle?
is that compass is a magnetic or electronic device used to determine the cardinal directions (usually magnetic or true north) while binnacle is (nautical) the wooden housing for a ship's compass, with its corrector magnets and illuminating arrangements; the log and other equipment for measuring the ship's speed is also stowed there.

Why do we put compass correctors?
Correctors may be permanent magnets or soft iron, which are placed adjacent to the compass. This creates equal, but opposing magnetic fields, thus nullifying the deviating fields around the compass, enabling it to align correctly.
Do ships still use compasses?
Despite advancements with GPS, the compass is still a valuable tool. Many airplanes and ships still use highly advanced compasses as navigational instruments.
How many compasses are there in a ship?
There are two types of compasses in use. The dry card compass is generally used as a standard compass & the wet card compass as a steering compass. The dry card compass is very sensitive.
How does a compass work on a steel ship?
A ship made of steel contain magnetic properties. It therefore has an inherent effect on magnetic compass. Compass needle on board does not lie on the magnetic meridian but is deflected on one side or the other because of the ship's magnetism.
Who invented the ship's compass?
No one is exactly sure who invented it (probably the Chinese, but the Greeks also understood about magnetism in ancient times), but the magnetic compass as a shipboard navigational instrument first shows up in the historical record in the early 1400s, when the Chinese explorer Zheng He (1371-1435) used them to lead a ...

A binnacle is the housing for a ship’s compass. The idea behind a binnacle is to counter the magnetic deviation caused by the ship being made of iron ...
How was the compass illuminated?
The compass would have been illuminated by an electric light that was housed inside the binnacle, below the compass. On the front of the binnacle is a clinometer which is filled with liquid and is used to give the list (angle) of the ship up to 50 degrees.
What could throw off the Titanic compass?
Even a small piece of iron such as a nail or screw could throw the compass off. The Olympic, sister ship to the Titanic, utilized four different binnacles to assist in navigating the high seas. The first one was on the navigating bridge.
What is the hood on a binnacle?
The top of the binnacle has a brass hood . This was used to protect the compass and cut down the amount of light at night so that anyone working around it would not lose their night vision. The hood also has two access sliding doors; one is on the back side and the other is on the right side.
Where was the fourth binnacle?
Further back on the docking bridge was the fourth binnacle. The binnacles in these last two locations were completely exposed to the elements so they would be covered when not in operation. It is quite possible that this particular binnacle was located on either the Olympic’s wheelhouse or compass platform.
Where are the binnacles on a ship?
Binnacles are typically made of wood or brass or other non-ferrous metals. They are located in a place on the ship to allow the ship’s navigator to determine position and course. They may be located near the helm so that the sailor steering the ship can maintain the correct course.
What is the magnetic field around a compass?
The compass contains a magnet (or magnets) that orient predictably to the magnetic field of the earth. In an ideal situation the compass would respond only to the earth’s magnetic field and would indeed always point to the Magnetic North Pole. In reality however, the compass magnet responds to the local magnetic field around it. That local field is a combination of the earth’s field modified by nearby magnetic influences. Anything containing iron— everything from ballast stones with high iron content to ferrous (iron containing) metals such as nails and other fasteners, rigging, electrical equipment, engines and other machinery and of course iron and steel hulls— distort the local magnetic field around a compass. Ships with hulls made of iron or steel have very significant local distortion but even wooden (or fiberglass) vessels contain sufficient ferrous metals to influence the local magnetic field around the compass.
What is a compass house?
This “little house” helps to protect the delicate compass from the elements. They usually contain a gimbal arrangement to hold the compass card horizontal despite the motion of the ship. In addition the binnacle usually contains a light of some sort to illuminate the compass face to facilitate reading it in the dark and shades to make reading it in sunlight easier. Binnacles are typically made of wood or brass or other non-ferrous metals. They are located in a place on the ship to allow the ship’s navigator to determine position and course. They may be located near the helm so that the sailor steering the ship can maintain the correct course.
How often do ships need a compass?
International maritime treaty regulations require that all ships carry a compass that has been swung at least every two years. [3] Requirements and Guidance for Magnetic Compasses according to Chapter V, Regulation 19 of the Safety Of Lives At Sea (SOLAS) Convention under the International Maritime Organisation (IMO). Even so, it is a regular part of the “Day’s work” for the Ship’s Navigator to check the accuracy of the compass by piloting methods if close to land and methods of celestial observation while at sea. [4] Nathaniel Bowditch, “American Practical Navigator, HO No. 9,” 1947. This regular check ensures that the accuracy of the compass has not been lost inadvertently and unnoticed by some event which has altered the local magnetic field of the ship or the adjusters. If errors are found they would be noted and used to correct compass bearings. If gross errors (as might be expected after a lightning strike or physical damage to the binnacle) are discovered then the navigator would need to be prepared to make compass adjustments at any time during a voyage.
What is the purpose of a compass?
At night, or otherwise out of sight of familiar landmarks, a compass provides vital information for the navigator. The compass on ships is often mounted in a binnacle which is a stand or housing. Its delightful name Binnacle derives from Latin habitaculum meaning “little dwelling place”.
Why would the compass need adjustment?
But why would the compass need adjustment, it is always supposed to point North, right? The reason is that as a critical piece of navigational equipment the accuracy of a ship’s compass can literally mean the difference between life and death for a ship and her crew. The compass’ accuracy must be maintained at the highest possible precision while at sea.
Where is the binnacle on the Wavertree?
You will notice that on Wavertree the binnacle is located on a platform up over the deck and away from other structures. This is in an attempt to minimize the effects of the magnetic properties of the iron ship and to place the compass close to the magnetic center of the ship. The binnacle located on the catwalk of the 1885 cargo ship Wavertree.

What is the purpose of a binnacle?
Its traditional purpose was to hold the ship's magnetic compass, mounted in gimbals to keep it level while the ship pitched and rolled. A binnacle may be subdivided into sections and its contents typically include one or more compasses and an oil lamp or other light source. Other devices such as a sand timer for estimating speed may have been stored in the binnacle as well.
Why were binnacles used?
The construction of many early (mid-18th century) binnacles used iron nails, which were later discovered to cause magnetic deviations in compass readings. As the development of the compass and understanding of magnetism progressed, greater attention was given to binnacle construction to avoid compass disturbances caused by iron.
Who invented the binnacle?
In 1854, a new type of binnacle was patented by John Gray of Liverpool which directly incorporated adjustable correcting magnets on screws or rack and pinions. This was improved again when Lord Kelvin patented in the 1880s another system of compass and which incorporated two compensating spheres.

Can you move a Garmin 640 compass away from the helm?
I'd never move the compass away from the helm. It's one of the items that you should frequently compare with your GPS heading if you are using one. There are numerous options if real estate is at a premium. The new Garmin 640 touch screen is hardly larger than the unit itself. Imagine where you want the unit, chances are there is a Ram Mount that will get you there.
Can you rely on a compass after a lightening strike?
Nice try, but lightening strikes have massive magnetic pulses too that tend remagnetize and throw off a compass. After a strike you cannot rely on your compass without verifying it.
Do you need lightning to ruin a compass?
Heck, you don't need lightning to ruin a binnacle compass. That's one reason why genuine "Navy" belt buckles are BRASS. Yes, compasses have been driven mad by simple belt buckles.#N#Fishsticks, the main reason I was thinking "binnacle" for the plotter instead of having it bolted on, or mounted on an arm, etc. is that it is next to impossible for a stray loop of line to rip the top off a binnacle. But easy to rip off any kind of mount or arm. One less thing to foul, one less thing to fail.#N#I suppose the compass could be mounted like a giant deck prism in the cockpit floor itself.<G>
