ONWA K-Astral & ONWA KM: two MFD lines, each with its own application
ONWA offers two full-fledged Multifunction Displays (MFDs) with the K‑Astral Series and the KM‑Series. Both series are built on the same ONWA foundation: reliable hardware, extensive navigation functions, and support for common chart formats.
The main difference lies in operation, system setup, and application area.
ONWA K‑Astral Series
Modern touchscreen MFD with a focus on ease of use
The K‑Astral Series is designed as a modern, clear MFD for users who want to work quickly and intuitively. The high-quality touchscreen forms the basis of the operation, supplemented by physical buttons for situations where that is desired.
Features
- 8″ or 12″ high-brightness touchscreen (sunlight-readable)
- Operation via touch, zoom, and swipe
- Support for K‑Chart (free), Navionics+, and C‑MAP Discover X / Reveal X
- Connections for NMEA0183 and NMEA2000
- Available in versions with AIS, fishfinder, and radar support
Positioning The K‑Astral is intended as a standalone navigation center or as part of a simple network. The focus is on clarity, speed, and direct interaction with the chart and sensors.
Typical applications
- Recreational sailing and motorboats
- Modern yachts with one primary MFD
- Users transitioning from tablet navigation to a fixed installation
- Situations where simplicity and clarity are more important than system complexity
In short
The K‑Astral Series is suitable for those looking for a modern, easy-to-use MFD without unnecessary system complexity.
ONWA KM‑Series
Full-fledged system MFD for integration and expansion
The KM‑Series was developed as an extensive system MFD, with integration and network functionality at its core. This series is suitable for installations where multiple sensors, screens, and data streams come together.
Features
- Operation primarily via buttons and rotary knobs
- Support for NMEA0183, NMEA2000, and ONENET (IP network)
- Can function as a data hub and protocol converter
- Interconnection of multiple KM‑MFDs possible
- Variants with built-in Class B+ AIS, fishfinder, and radar functionality
Positioning The KM‑Series is designed as a central component within a larger navigation system. Radar, sonar, and AIS data can be shared between multiple displays on board.
Typical applications
- Larger sailing and motor yachts
- Vessels with multiple helms or displays
- Long-distance and intensive use
- Workboats, training vessels, and technical applications
In short
The KM‑Series is intended for users seeking maximum integration, expandability, and system reliability.
Similarities
Both series offer:
- Professional quality ONWA hardware
- 8″ and 12″ high-brightness displays
- Support for AIS, radar, and fishfinder (depending on the version)
- Compatibility with K‑Chart, Navionics+, and C‑MAP
- Suitable for 12V and 24V systems
Which series is the best fit?
| K‑Astral Series | KM‑Series | |
|---|---|---|
| Operation | Touchscreen + buttons | Buttons |
| Focus | Ease of use and overview | Integration and system operation |
| Network | Simple / optional | Core functionality |
| Installation | Relatively simple | System-oriented |
| Application | Recreational | Advanced / professional |
