Axiom+ 12, Multi-Function 12″ Display
Best for tech-forward boaters who want high performance and sharp visuals. The Axiom+ 12 uses a powerful quad-core processor with increased onboard storage for apps and data. IPS technology provides wide viewing angles and strong contrast at high resolution, while the nano-coated glass resists water, oil, and smudges for accurate touch controls. This display is well suited for sailors who rely on multitasking on screen and need reliable touch input in rough conditions.
Who it’s best for: captains who run charting, radar, and apps on one display and demand fast responses. Limitation: higher data requirements may necessitate careful network setup and power management.
Raymarine i70s Multifunction Instrument Display
Best for upgrading older systems with a compact, trusted instrument display. The i70s line is a well-regarded choice for straightforward instrument readouts, offering reliable performance in a smaller form factor. It’s suitable for boats that need a practical, proven solution without the need for large-screen multitasking.
Who it’s best for: boaters who want dependable instrument data in a compact display. Limitation: simple feature set compared to larger multitasking MFDs.
Part Synergy TD 50 Replacement 5″ MFD
Best for budget-minded buyers seeking a direct-fit 5″ touchscreen option. The TD 50 replacement provides a bright display (1200 nits) with IPX7 water resistance, making it a practical upgrade for smaller dashboards or as a spare unit. It is a solid entry point for basic navigation and engine monitoring in harsh marine environments.
Who it’s best for: boaters needing a compact, bright touchscreen without premium features. Limitation: limited multitasking compared to larger MFDs.
FILFEEL High-Quality Engine Instrument Panel
Best for robust engine-focused monitoring with wide operating ranges. This instrument panel provides precise readings for engine RPM, temperature, oil, fuel pressure, and voltage. It features a stainless-steel bezel and an IP67 rating, designed to withstand harsh marine conditions and temperature extremes. The compact footprint helps conserve dash space while delivering essential engine data.
Who it’s best for: operators needing comprehensive engine metrics in a rugged, weatherproof panel. Limitation: primarily engine data, with less emphasis on navigational multitasking.
Lewmar Single Boat Joystick Control
Best for precise, ergonomic control in tight berths or docking situations. The Lewmar system offers an ergonomic control pad with tactile feedback and a sealed membrane switch panel to resist dust and moisture. It’s a solid option when joystick control and multi-function LED display capabilities are needed on compact consoles.
Who it’s best for: boaters prioritizing ease of docking and weatherproof switch panels. Limitation: primarily a control and display console component rather than a full MFD.
Bluetooth Marine Boat Radio Receiver
Best for adding reliable audio capabilities to a marine cockpit. The Bluetooth-enabled radio supports AM/FM, USB, AUX-in, and built-in EQ for customizable sound. It’s suitable for boats where integrated audio is a priority, and where water exposure warrants IP-rated protection. Note: does not include CD playback.
Who it’s best for: owners wanting an all-in-one audio system on deck or in cabins. Limitation: not a navigation or engine data display; separate MFDs are still required for full marine data.
LED Marine Navigation Light
Best for simple, high-visibility navigation lighting. This digital multifunction light offers adjustable mounting and a visible lubber line for accurate directional readings. It provides ease of installation and reliable daytime/nighttime readability, with the option to connect to external power supplies as needed.
Who it’s best for: boaters needing visible navigation lighting with straightforward mounting. Limitation: not a display unit; complements MFDs rather than replaces them.
Part Synergy Remote Control For MFD
Best for expanding control options on a primary MFD. This remote control is designed to work with NavNet TZtouch and related displays, enabling flush-mount setups with a compact 9x5x4 inch footprint. It helps captains manage display navigation without reaching for the helm compared to traditional controls.
Who it’s best for: boats needing flexible, remote display navigation. Limitation: compatibility varies by system; verify existing MFD compatibility before purchase.
Buying Guide: Key Considerations
- Display size and visibility: Larger screens are easier to read at a distance, especially in bright sun. Consider IPS or high-brightness panels for better legibility.
- Processing power and storage: High-performance MFDs handle simultaneous charting, radar, sonar, and apps. Ensure onboard storage meets your data and app needs.
- Durability and protection: Look for IP ratings, anti-glare coatings, and resistant glass to withstand salt spray and cleaning solvents.
- Integration: Check compatibility with your existing gear (radar, autopilot, instrument clusters, and network protocols).
- Power and mounting: Verify voltage requirements and mounting options. Some displays are better suited for flush mounts in tight cockpits.
- User interface: Touch vs. physical controls. Touch can be versatile, but some helm layouts benefit from tactile instrument clusters.
- Audio and auxiliary features: If you want music or alerts, consider models with Bluetooth or integrated audio options and easy alert visibility.
FAQ
- What is an MFD and why do I need one?
An MFD consolidates navigation, engine data, and sensor information into a single display, simplifying monitoring and decision-making while at sea.
- Which MFD size is best for small boats?
Smaller boats often benefit from compact 5″ to 9″ displays for easy cockpit integration without crowding the dash.
- Do MFDs require special networks or wiring?
Most needs involve NMEA 2000 or similar networks and adequate power. Verify compatibility with existing gear during selection.
- Are waterproof ratings essential for MFDs?
Yes. IP ratings help ensure operation in spray-heavy environments and during rain or washdowns.
- Can I mix brands for an MFD setup?
Yes, but ensure network compatibility and supported interfaces to avoid data loss or poor performance.
- What is the advantage of an IPS panel?
IPS panels offer wide viewing angles and stable color accuracy, making it easier to read data from various helm seating positions.
