Raymarine ST60 Long Arm Masthead Transducer w/30m Cable

Description

The Raymarine ST60 Long Arm Masthead Unit is a wired wind sensor for sailing boats replacing an existing masthead vane or anemometer. It measures apparent wind speed and direction, then sends that information to a compatible Raymarine instrument or interface module. This is a sensor-only product, so it does not include a display, charting, or standalone wind-processing electronics.

The long 570mm arm helps place the sensor clear of mast turbulence, while the supplied 30m cable gives useful reach on taller cruising yachts. Wind direction resolution is under one degree, and speed is measured to 0.1 knots. The five-wire analog connection feeds an i60, ST60+, or ITC-5 system. For NMEA 2000, the ITC-5 is required, so this is not a direct NMEA 2000 sensor.

Key Features

• Apparent wind speed and angle – Provides the core wind data used by compatible Raymarine instruments.
• Under 1° direction and 0.1-knot speed resolution – Gives useful precision for sailing trim and basic wind monitoring.
• 570mm long arm – Helps position the sensor above mast turbulence.
• 30m cable included – Provides reach for taller masts and longer cable runs.
• IPX6 protection – Suits exposed masthead installation in marine conditions.

Who Is This For?

This Raymarine masthead wind transducer suits cruising yachts and sailboats replacing a compatible ST60 wind sensor. It is not ideal for a new system without an i60, ST60+, or ITC-5 connection, because the sensor has no display and uses a proprietary five-wire analog interface.

Compatibility

Confirmed compatibility includes Raymarine i60 Wind, ST60+, and ITC-5 through the analog connection. NMEA 2000 operation requires the ITC-5 interface. The supplied information does not identify direct Garmin, B&G, Simrad, NMEA 0183, or third-party display compatibility. No named incompatible system was provided.

Warranty & Support

Raymarine provides a 2-year standard warranty. The supplied specifications do not state warranty exclusions or service procedures.

The ST60 long-arm sensor is the practical choice when the existing Raymarine wind display and wiring are still usable. Its trade-off is the older analog architecture: it is a direct replacement for the specified Raymarine system, but not a universal NMEA 2000 wind sensor. Choose it when compatibility with i60, ST60+, or ITC-5 equipment is confirmed.
