Best fixed compasses: 6 options for binnacle and bulkhead mounted units
Every sailor needs a reliable and dependable fixed compass in the cockpit, allowing safe navigation while keeping on a straight heading. We pick out 6 of the best fixed compasses, both binnacle and bulkhead mounted....
Fixed compasses are an essential piece of kit that every yacht needs They are especially good in this day & age, as they do not need any electrical power to run. They can get you where you are going and back home again safely, even in the event of an onboard power outage.
Operation
Under the compass card is a small magnet which lines up north/south using the Earth’s magnetic field. Then the whole compass is encased in a damping fluid to give a stable heading at sea.
Deviation
Many things may alter the compass alignment. Deviation is caused by onboard metal, such as your engine, cockpit speakers and even the wires supplying power to your compass light. Consequently, all compasses then need to be adjusted using small compensating magnets inside the compass. Usually, this needs the hand of an experienced compass adjuster, during a process called “swinging the compass”.
Compass Styles
Traditionally, binnacle compasses are mounted directly in front of the wheel. These compasses have a flat card, which is only viewed from above. Usually they are mounted on a platform, to raise them up from the pivot point of the wheel. Also they tend to be larger, giving a clearer vision
Smaller yachts and those with tiller steering, usually have bulkhead mounted compasses at the front of the cockpit, to one side of the companionway. One advantage of these, is they mostly come with a built in clinometer, showing your angle of heel. Knowing this, also helps you to decide when to put that reef in. Many of these have hybrid dials. This allows you to read the compass from above, as well as when stood in the cockpit at the helm.
The downside is, you need a hole to be cut in your boat to fit the compass.
