How to Choose the Best Boat Compass: The Ultimate  Buying Guide

A boat compass is one of the simplest yet most crucial gadgets to have with you as you explore the open waters. While most boats may come fitted with an electronic navigation system, it’s still important to carry a compass with you so that you may never lose your way. With the widespread popularity of Global Positioning Systems (GPS), many outdoor lovers have opted out when it comes to compasses. But your GPS may lose its signal due to interference, and a good old compass and map will come in handy.

How Does a Boat Compass Work?

Every marine compass has a lubber line which points to the direction on the compass card. The compass card sits at a degree on the bearing and easily rotates as you change directions. The compass card is kept in a liquid to ensure that it moves freely. The most common type of compass that you are likely to come across is a magnetic compass that always gets its bearing from the magnetic north.

Types of Norths

To fully understand how a compass works, it’s important to differentiate between the three types of North that are crucial when navigating. They are;

Grid North – When navigating, you always need to carry a map. The vertical grid line that is running east of the United Kingdom on your map is the grid north.

True North – This is the end of the earth’s axis and has a negligible difference from the grid north.

Magnetic North – This is the direction that all magnetic compasses point to and is usually shifts about 6 meters per year due to the earth’s forces.

Mounting Compasses

Marine compasses are categorized depending on their mounting style which can be;

  • Flush Mount – This is where the boat compass is in a cutout on a horizontal surface where half of it is on the surface while the rest is below.
  • Bracket Mount – These types of compasses are quite versatile since they allow you to mount using different tilt angles and are easily removed for storage.
  • Surface Mount – They usually rest on the top of a surface and can be removed easily by pressing a button and don’t need holes to mount.

Factors to Consider When Choosing a Boat Compass

There are several factors to keep in mind as you shop around for the ideal boat compass to help you with navigation. They are;

  • Type – Most sailors opt for magnetic compasses compared to the electronic ones since they are rarely affected by electric signals. That said, electric compasses can be fitted with sophisticated sensors that help provide a more accurate reading.
  • Accuracy – A properly calibrated compass will get you home safe. Ensure that your choice can be easily calibrated and doesn’t need constant adjusting as this may complicate navigation due to inaccurate readings.
  • Mounting style – As discussed above, there are various ways that you can mount your compass. Your choice will depend on your dashboard and the type of boat you own.
  • Shape – You will come across three shapes when looking for a marine compass; flat, conical, and cylindrical. The flat compasses are best suited for large vessels since they are more stable and don’t keep toppling over when in rough water. If you love sitting on the helm of your boat, then the conical compass is the best choice.
  • Readability – Larger compasses are easier to read and interpret. It’s also important to ensure that the compass can be easily read in bright sunlight and even in the dark.


With a well-calibrated compass and a maritime chart, you will rarely get lost out there. Compasses have been used for centuries, and sailors have always depended on their accuracy to find their way home. We have featured the best boat compasses that you can count on for your expeditions out in the water.
