PRE OWNED SIMRAD AP-35 SIMRAD AP-35 MARINE AUTOPILOT

The Simrad Robertson AP35 is a heavy-duty, commercial-grade autopilot specifically engineered for the rigorous demands of the fishing industry and workboat sectors. In the Bhavnagar and Alang markets, it is highly prized for its "Work Mode" and its rugged aluminum construction, which stands up to the harshest maritime environments.

SIMRAD ROBERTSON AP35 COMMERCIAL AUTOPILOT

PRODUCT OVERVIEW

The Simrad AP35 is a dedicated professional autopilot that prioritizes simple, tactile operation. Unlike leisure models, it features a solid aluminum casing and large, dedicated push buttons for every major function, allowing for reliable use even when wearing gloves or in rough seas. It is a preferred partner for small-crew fishing vessels that require precise steering during both high-speed transit and low-speed work operations.

The system is famous for its WORK Mode, which allows the autopilot to immediately adapt to specialized tasks like trawling or hauling gear. In this mode, the rudder response is automatically increased to maintain a steady heading against the drag of fishing nets or heavy loads. Combined with its rotary course selector knob—a hallmark of Simrad Robertson precision—the AP35 offers the perfect balance of manual control and automated accuracy.

KEY FEATURES & APPLICATIONS

-- Dedicated WORK Mode: Automatically adjusts steering parameters for slow-speed operations and increased rudder response, making it ideal for fishing and towing.

-- Manual Rudder Trim: Provides immediate access to offset the rudder, allowing the operator to compensate for side-forces like wind or prop-walk that might pull the boat off course.

-- Rotary Course Selector: A highly valued feature for commercial mariners, allowing for quick and precise 1-degree or 10-degree course changes without looking at the screen.

-- Automated Maneuvers: Includes easy-to-activate U-Turn and C-Turn (continuous circle) functions with adjustable radius settings for search patterns or net setting.

-- Multistation Reliability: Utilizing the Robnet data network, multiple AP35 stations can be linked. A safety "Lock" feature prevents other stations from taking control during critical maneuvers.

-- Navigation Mode (NAV): When connected to a GPS or Chartplotter via NMEA 0183, the AP35 can steer along complex pre-planned routes with arrival alarms at each waypoint.

TYPICAL CONDITION (USED/REFURBISHED)

Refurbished AP35 units from Alang are exceptionally durable. We verify the "WORK" and "AUTO" button responsiveness and ensure the rotary encoder provides a distinct "click" for every degree of course change. The LCD is checked for clarity and backlight uniformity, and the Robnet ports are tested for communication with J300X junction units. Since these are often installed on workboats, we also inspect the aluminum housing and seals to ensure the IP56 water resistance remains intact.
