Stay Balanced: The Best Clinometers for Your Boat
Clinometers: see how much you're actually heeling. A clinometer measures your boat's angle of heel, how far it lists to port or starboard. Sounds simple, and it is, but your perception can deceive you: on board, you're heeling along with the boat, and then ten degrees can easily feel like twice as much.
For sailors, it's a trim question. Every sailboat has an optimal angle of heel, for most yachts somewhere around fifteen to twenty degrees. Above that, you lose speed: the rudder has to work harder, the hull is less favorably positioned in the water, and you create unnecessary leeway. A clinometer shows when it's time to reef, instead of having to guess.
For motorboaters, it's a stability question. A persistent list indicates uneven loading, a shifted tank, or water where it shouldn't be. A clinometer makes this visible before it becomes a problem, and helps with evenly distributing weight.
Our clinometers work on gravity: a damped liquid or a weighted pointer that indicates the angle, without power and without calibration. This makes them indestructible and always available.
Available in brass, chrome-plated brass, and stainless steel, to be mounted on the bulkhead where you can see them while sailing. Classic in form and thus round, these instruments have hardly changed over the years, except that the quality remains. Also check out compasses or the complete overview under navigation & sailing.

Frequently asked questions
A clinometer, also known as an inclinometer, measures the angle of slope or tilt relative to a horizontal plane. It is often used on boats to monitor stability and heel angles.
A clinometer helps you see how much your boat is heeling while sailing or at rest. This is important for safety, comfort, and optimizing the boat's performance.
Most inclinometers are easy to mount. They are usually attached to a flat, visible spot, such as on the dashboard or against a wall. Check the manual for specific installation instructions.
There are analog inclinometers with a mechanical scale and digital inclinometers that measure the angle of inclination electronically. Choose a model that suits your needs and the situation on board.
Indeed, that's right! Inclinometers are specifically designed for use on moving vehicles such as boats. They remain accurate thanks to gravity-based or gyroscopic mechanisms, even with slight movement.
