Types of Boat Compasses

As we’ve outlined in our top boat compass picks above, compasses come in a variety of shapes, sizes and mounting options for boaters. 

To provide you with a little more background on each type, the following section breaks down what you can expect when choosing the right compass for your watercraft. 

• Flush mount – A flush mount compass is installed directly into an existing hole or cutout on your boat. The compass literally drops into place, providing a clean and streamlined look that is both professional and highly aesthetic. With a flush mount compass, the compass lies flush against your boat’s surface, providing a more integrated feel for boaters. 
• Surface mount – A surface mount compass looks to mimic the streamlined design of a flush mount compass on vessels where installing a cutout simply isn’t possible for one reason or another. Surface mount compasses sit on top of a section on your boat and can be held down with brackets, fasteners or glues. They are extremely easy to install and provide a quality mounting option for boats that can’t or don’t facilitate an easy solution for existing instrument cutouts. 
• Bracket/Dash Mount – Dash mount compasses are built to be mounted on a boat’s dashboard or console, which provides easy and effective viewing for boat captains. Often times they are offered with a bracket setup the allows for an adjustable viewing angle. They are popular options on smaller powerboats and help to provide a clear reading of navigational headings without having to compromise on space or more challenging installation options. 
• Instrument Dash Mount – Instrument dash-mounted boat compasses are installed and integrated into existing instrument panels on a boat to help save space onboard. They are often mounted directly next to other instruments for easy, all-in-one access to critical maritime functions. 
• Illuminated Compasses – Illuminated compasses are pretty straightforward and obvious. They provide effective nighttime illumination that allows boaters to take accurate navigational readings in day, night, and low light conditions at sea. While most compasses now come with some sort of option for nighttime readings, it is important to consider this feature if you are running any type of nighttime operation as a recreational boater.  
• Bulkhead Mount – A bulkhead mount compass is installed on a vertical surface or bulkhead, hence the name. Often these compasses are installed in a boat cabin or helm area and are traditionally very popular on recreational sailing vessels where accurate navigational readings are necessary even in times when a sailboat is on heel.  

How Does a Boat Compass Work?

A compass is a critical navigational tool that works using Earth’s magnetic field. 

At a basic perspective, it helps determine direction by pointing to Earth’s magnetic North Pole. 

Some of the ways the a compass works include:

1. Earth’s Magnetic Field: Our beautiful planet Earth acts as one giant magnet with its magnetic field extending from the North to the South pole. The magnetic field interacts with the magnetized needle which is a primary component of a boat compass. 
2. Magnetized Needle: Made of a lightweight material like steel or aluminum, the primary component of any boat compass is a magnetized needle. This magnetized needle is mounted or balanced on a pivot point that allows it to rotate and turn freely. 
3. Aligns with Magnetic North: Once the magnetized needle is free-floating, it automatically aligns itself with Earth’s magnetic field, helping to point to magnetic north and south poles. 
4. Reading the compass: To accurately read a compass, you simply observe the direction in which the “north” end of the magnetized needle is pointing. This provides you with a reference to magnetic North, which can in turn help you determine your relative heading in relation to the magnetic north. 
5. Accurate readings: In reading a compass it is important to note that there is a difference between magnetic north and true or geographic north. This is where declination is critical with compasses, as declination adjustments can help you correct for differences to help obtain a true north reading. Similarly, magnetic disturbances can take place in compasses, which can affect the accuracy of readings. For more precise readings, it is essential to make sure that your compass is properly calibrated.  

Boat Compass Buying Guide & Important Considerations

Having a reliable boat compass can make all the difference to boaters on the water.

Not only do they help lead you home on the right course, but they provide critical peace of mind to help back up many of today’s modern technology onboard boats including chart plotters and GPS.

While purchasing your next boat compass is pretty easy to do with all of the options online today, there are a number of factors that you may need to consider in order to choose the best-fit model for your unique boating life.

Some of these important considerations include:

Boat Size & Type:

How big is your boat?

Are you navigating a 70-foot motorsailer or choosing a compass for a 13-foot Boston Whaler?

Larger vessels require totally different compass requirements than smaller boats, so it is important to select a boat compass that is specially suited to your boat’s unique design, shape and size.

Mounting Location & Size:

One of the most critical components of choosing a new boat compass comes down to the mounting option you need to best fit your boat.

We have covered this in the section above, but it’s critical to know how your new compass will best be mounted to your boat for both accurate readings and easy viewing.

Any mounting location should be planned to help provide clear visibility with convenient viewing for anyone at the helm.

Navigational Needs:

How will you be using your compass onboard your boat?

Are you choosing a new compass for offshore use? Lakes and rivers? Or coastal cruising?

Knowing how you intend to use your new boat compass will help to point you in the right direction in terms of your chosen boating environment.

Illumination Capabilities:

Do you plan on navigating in nighttime or low-light conditions?

If so, choosing a boat compass that provides a solution for illumination of your navigational readings is critical.

Built-in LED lighting is a great solution for boaters who want to make sure that navigational readings can be made easily, quickly, and accurately in any lighting conditions on the water

Global Balancing:

If you are one of those rare boaters who are planning for extensive voyages across the hemispheres, then choosing a boat compass that has a built-in global balancing feature is a must-have.

Global balancing provides consistent accuracy for boaters in an extended capacity that can be absolutely critical for extended long range crusing.

Clear Compass Card & Dial:

Any compass should be easily visible and readable to help provide accurate navigational readings.

Before purchasing your new boat compass be sure to make sure that the compass card and dial are clearly visible and include a high-contrast design to help make your navigational readings a breeze.

Gimballed Mounting:

Next up on our list of important considerations is the feature of gimballed mounting options that allow compasses to stay accurate and level even in extreme weather and rough sea conditions.

You want to be able to have an accurate navigational reading even when your boat is tilting, so choosing a boat compass that is built with a gimballed mounting can be critical for boaters.

Adjustable Deviation:

Different magnetic disturbances can influence precise readings in your boat compasses.

Be sure to choose a boat compass that allows you to fine-tune deviations in the compass readings to account for different magnetic disturbances.

Compass Size & Visibility:

Next up on the list of critical factors in choosing a new boat compass comes down to the size and overall visibility of a boat compass.

Making sure to choose a compass that is appropriately sized to fit both your mounting style and boat size can make all the difference in terms of choosing a best-fit option for your boating needs.  

Compensators & Correctors:

Some more advanced compasses can include compensators to help account for changes in the Earth’s magnetic field. 

Choosing an option that includes compensators and correctors is especially helpful in long-range cruising and more advanced navigation needs for more professional boaters and Captains. 

Cost and Warranty:

Next up on our buying guide for the best boat compasses is the consideration of cost and warranty.

While obvious, it is critical to choose a system that fits your budget while providing the necessary features and functions to keep you safe on the water.

Similarly, since this is a critical piece of technology on your boat look out for products that include a no-questions-asked warranty so that you can have the peace of mind needed while on the water.
