Autopilot Accessories

RAI ANALOG METER

Part No. 20360023

The analog rudder angle indicator is a backlit 76mm (3in) gauge displaying the actual position of a vessels rudder. All ComNav Autopilots come with built in electronics to drive at least three meters without additional interfacing.

Highlights of the RAI include:

• Flush Mount

• Water Resistant front face

• Supply voltage for lighting 10-40VDC

• Optional Bezel Kit (P/N:30360004)

• Optional Wheelhouse Case (P/N:20360017)

• Optional Watertight Case (P/N:20360016)

RAI WATERTIGHT CASE

Part No. 20360016

The Rudder Angle Indicator Watertight Case is a good alternative for outdoor applications where flush mounting the RAI may not be possible. In these cases or, when the back of the RAI may be exposed to moisture, we recommend the watertight case. The kit comes complete with case, O-ring seals, screws and two watertight cable glands.

STAND ALONE RUDDER ANGLE INDICATOR SYSTEM

Part No. 10360001

Complete single station RAI System typically used on vessels that do not have a ComNav autopilot or, in cases where a separate RAI system is required (such as Hydraulic Full Follow-up steering systems). The Stand Alone System consists of three components:

• ComNav Rudder Follower w 15.2m(50ft) cable and linkage kit

• RAI Distribution Box with special circuitry

• ComNav 76mm (3in) Rudder Angle Indicator

These motors are usually found on older reversing electric pump sets or mechanical drive autopilots. The box is transistorized "reverse pulse" braking control box. Retrofits existing 3-wire motors.

Highlights of the CT3 Drive box include:

• Solid state circuitry

• Anodized aluminum housing (watertight if installed correctly)

• 10 - 40VDC

• Rated 20 Ampere

CT4 AC INTERFACE - AC 115-220VAC

Part No. 20350003

The ComNav CT4 is used in situations with the steering interface that has 115 or 220VAC solenoids.

Highlights of the CT4 drive box include:

• Solid state circuitry

• Anodized aluminum housing (watertight if installed correctly)

• Uses zero crossing to detect triacs for maximum reliability (ensure noise is not generated in the 115/220VAC system)

CT5 DRIVE BOX - TWO SPEED DRIVE

Part No. 20350004

The ComNav CT5 Drive Box is used to connect ComNav Autopilots to vessels using two speed (dual rate) DC solenoid valve systems. The CT5 is a recommended accessory for any Two-speed Uniblock manifolds steering system.

The Drive Box will simultaneously control a directional solenoid valve as well as a rate valve which is used for changing the flow from a low pre-set speed to a high (maximum flow) speed. The rate output will control any additional electro-hydraulic 4-way solenoid valve.

Highlights of the CT5 Drive Box include:

• Solid state circuitry

• 10 - 40VDC operation range

• Cast aluminum construction

• Operates a rate valve (dual speed) in addition to a standard 4-way directional valve

MEDIUM DUTY RUDDER Follower/Feedback & Linkage

Part No. 20330008 & 20330007

The ComNav Medium Duty Rudder Follower, or Rotary Feedback, provides the Autopilot with information about the physical position of the rudder. This is necessary to provide optimum steering performance and accuracy. The rudder follower package includes rudder follower, 15.2cm (50ft) cable, rudderpost arm, and adjustable linkage.

Features include:

• Horizontal or vertical mounting positions

• Snap together assembly

• Stainless steel, brass and plastic construction

• Watertight glass fiber reinforced housing

LINEAR Rudder Feedback - OUTBOARD Feedback

Part No. 20330002

The linear feedback works with all ComNav Autopilots except the 2001. The Linear Feedback uses a simple, stainless steel, band clamp to attach to the cylinder. The Linear Feedback can be used with hydraulic cylinders from 3.18 - 5.72cm(1.25-2.25in) diameter with strokes up to 25.4cm(10in) 9.1cm (30ft) of cable in included.

LINEAR ACTUATOR - DRIVE FOR SAIL BOATS (Mechanical Steering)

The Linear Actuator is for use with the existing mechanical steering systems and consists of a hydraulic steering cylinder, a reversing pump set, a lockup solenoid valve (electrical by-pass valve). It is economic; easy to install and even comes pre-filled with hydraulic oil. The Linear Actuator engages automatically when the autopilot is in use. It also offers the additional benefit of being an independent steering system providing a safety backup if the mechanical steering fails. For 1001/22001 Autopilots add a CT2 P/N 20350001.
