PRE OWNED FURUNO NAVI 4000 SPERRY MARINE NAVI 4000 MARINE AUTOPILOT

PRODUCT OVERVIEW

The Sperry Marine NAVIPILOT 4000 is a next-generation autopilot system that uses advanced network technology to ensure safe and efficient vessel navigation. Its standout feature is its continuous self-tuning adaptation, which allows the pilot to automatically adjust to the vessel's load, trim, and prevailing weather conditions. This unique adaptive capability significantly reduces rudder activity, leading to less mechanical wear and lower fuel costs.

The system is built on the NAVINET 4000 steering control network, offering a modular design that integrates seamlessly with other Sperry Marine bridge equipment. With a large, high-contrast graphical LCD and an intuitive menu structure, the NAVIPILOT 4000 provides bridge officers with clear situational data and easy control over complex steering maneuvers.

KEY FEATURES & APPLICATIONS

-- Self-Tuning Adaptive Logic: Automatically learns vessel response to optimize steering performance, which is particularly effective for ships with varying load characteristics.

-- Fuel Efficiency Mode: Minimizes rudder movements to reduce hydrodynamic drag, resulting in measurable fuel savings over long-distance transits.

-- Track Control Category B/C: When interfaced with a VisionMaster FT ECDIS, the system can autonomously steer along a programmed voyage plan.

-- High-Speed Craft (HSC) Features: Type-approved for high-speed vessels, providing the rapid response times required for safe navigation at elevated speeds.

-- Ergonomic Control Disk: Features a traditional cardinal control disk for analog selection of heading, combined with soft-keys for menu-driven parameter adjustments.

-- Modular Network Design: Utilizes CAN bus technology (NAVINET 4000) for easy installation and the addition of multiple remote control stations.

TYPICAL CONDITION (USED/REFURBISHED)

Our refurbished NAVIPILOT 4000 sets from the Alang/Bhavnagar yards are subject to comprehensive technical audits. We verify the "Self-Tuning" memory to ensure the unit correctly stores vessel parameters. The LCD is inspected for backlight consistency and graphical clarity. We bench-test the Steering Control Unit (SCU) and the Control Display Unit (CDU) to ensure the CAN bus communication is stable and the NMEA 0183 ports are parsing data correctly.
