The Risk of Touchscreen-Only Navigation and What You Should be Using Instead

Marine navigation systems have come a long way, especially as larger displays and touchscreen interfaces have become more common across vessel bridges. At first glance, it might seem like touchscreens could replace everything else, but once you step into actual marine conditions, a different problem shows up.

Touch-based systems highly depend on stability. Marine environments cannot always guarantee this. Movement on marine vessels, weather, and constant motion make it hard to rely on touch systems alone, especially when accuracy and safety are at stake. That is why trackballs and keyboards are still widely used — they solve problems that touchscreens cannot.

We’ll break down what works, what doesn’t, and how to choose the right input setup for your vessel.

The Problem With Relying on Only Touchscreen for Marine Vessels

When operators rely only on touchscreens for data entry, minor disruptions can turn into larger inefficiencies.

Vessel movement, changing weather conditions, and the need for precision can make it harder to input accurate information.

Leading to issues on board like:

Slower data entry when typing on a touchscreen.
Increased errors when entering coordinates or navigation details.
Difficulty making edits to routes.
Interruptions when switching between different tasks or systems.
Reduced efficiency during longer operations where repeated input is required.

Although these challenges may seem minor at first, over time they affect workflow and increase the likelihood of mistakes. Making it harder for operators to stay focused on navigation and system management.

In environments where logging, reporting, and system interaction are routine, inconsistent input methods can create unnecessary friction and slow everything down.

The Solution? A Stable Input System

The challenges of unstable control are solved by using input devices that are designed for marine conditions, not adapted to them.

Trackballs and keyboards work together to create a system that will remain usable even when conditions are not ideal.

Each one of these tools solves a different part of the problem. Together they provide a level of control and consistency that a touchscreen alone cannot match.

Trackballs support a more precise system control by allowing vessel operators to move the cursor without relying on a steady surface or hand position. This makes it easier to interact with tools like radar, ECDIS, sonar, and camera systems. At the same time, keyboards provide a more reliable way to handle structured input.

Tasks like logging data, entering coordinates, editing routes, and managing system inputs can be done more accurately and efficiently when there is a dedicated input method that is designed for that purpose.

When keyboard and trackball are combined, they create a balanced system that supports your vessel.

How these systems support your operations:

Provide stable cursor control during vessel movement.
Enable faster execution across systems.
Reduce possible input errors during critical operations.
Create a consistent workflow that holds up over time.

This is why marine navigation systems are built with multiple input methods. It is not about preference — it is about maintaining control, accuracy, and efficiency across changing conditions.

What to Look for in Marine Keyboard and Trackball Devices

Not all trackballs and keyboards are built for marine environments, so it is important to look at the standards that guarantee long-term performance.

Buyers should pay attention to:

IP ratings such as IP65 or IP67 for protection against water and dust.
MIL-STD-810 testing for shock and vibration resistance.
Salt fog testing to prevent corrosion over time.
EMC and EMI compliance to avoid interference with other onboard systems.
Backlighting and NVIS compatibility for low-light or night operation.

These features are not optional for marine use. They help guarantee that the equipment continues to perform under the conditions it will actually face.

When control matters, the input device you choose needs to perform consistently. Check out our top marine trackball and keyboard solutions below.
