PRE OWNED SIMRAD AP-11 SIMRAD AP-11 MARINE AUTOPILOT

PRODUCT OVERVIEW

The Simrad AP11 is an intuitive autopilot system that combines legendary Robertson steering software with a user-friendly interface. Designed for both power and sail vessels, it features advanced proportional rate rudder control and automatic sea state adjustments. This allows the AP11 to maintain a steady course even as conditions change, without requiring constant manual fine-tuning.

The system is highly modular, typically centered around the AP11 Control Head (P/N 22085237) and a J3000X Junction Unit. Its "Plug and Play" nature for its era, combined with NMEA 0183 support, makes it a popular choice for refitting older vessels where a dependable, standalone autopilot is required.

KEY FEATURES & APPLICATIONS

-- Simple Four-Button Operation: Designed for ease of use in heavy weather, allowing the operator to switch between Compass, Wind, or Navigator modes with one touch.

-- Adaptive Sea State Filter: Automatically compensates for changing sea conditions to provide smooth, proportional rate rudder control.

-- Dual Station Capability: Supports the addition of a second full-function control head or a handheld remote (R3000X) for steering from the flybridge or deck.

-- Chartplotter Integration: Connects via NMEA 0183 to follow pre-set routes. For safety, it includes a waypoint arrival alarm that requires manual confirmation before changing course.

-- Automatic Compass Calibration: Simplifies the installation process by automatically compensating for fixed heading errors during the initial sea trial.

-- Flexible Drive Support: Can control a wide variety of drive units, including reversible hydraulic pumps and mechanical linear rams.

TYPICAL CONDITION (USED/REFURBISHED)

Refurbished AP11 units from ship-recycling yards are thoroughly bench-tested using a J3000X test jig. We verify the LCD for any missing pixels or "sun-burn" and ensure all four tactile buttons are responsive. The NMEA 0183 input is checked for successful communication with GPS navigators. Since these units are often used as critical spares for existing systems, we pay special attention to the terminal blocks and the rear connector pins for any signs of salt-air corrosion.
