Overview

The Raymarine E70670 is an RSW Wired Smart Wind transducer with a short arm and 30 m mast cable for collecting calibrated wind speed and wind direction data at the masthead. It is made for wired sailing instrument systems where dependable apparent and true wind information matters for trimming sails, steering to a target, and reading changing conditions from the cockpit.

This transducer runs from a 12 V DC SeaTalk NG supply with a 9 V to 16 V DC operating range and draws less than 100 mW. It has NMEA 2000 LEN 1 network loading, so it can be integrated into a properly powered SeaTalk NG or compatible NMEA 2000 backbone without adding a heavy electrical load.

The masthead unit is rated IPx6/IPx7 for exposure to spray, rain, and washdowns, while the wired gateway is rated IPx3 for protected installation below deck. The included 30 m cable gives enough length for many mast runs, and the Smart Wind wired gateway handles the connection back into the onboard network.

Key features

• Short-arm RSW Wired Smart Wind transducer for masthead wind speed and direction measurement on sailing vessels.
• Supplied with a 30 m Smart Wind mast cable for routing down the mast to the gateway.
• Runs on 12 V DC via SeaTalk NG, with a 9 V to 16 V DC operating range and power consumption under 100 mW.
• NMEA 2000 LEN 1 network load for integration into a correctly fused marine data backbone.
• Smart Wind technology works without a separate wind processor or lengthy setup routine.
• Wind tunnel tuned for consistent readings from the masthead, including true wind use with Raymarine Alpha Performance Displays and Axiom chartplotters.
• Wind transducer rating of IPx6/IPx7, with operation from -25°C to +55°C for exposed sailing conditions.
• Rated for wind speeds up to 115 mph, with vibration testing to EN 60945:2002 exposed requirements.

Installation and system integration

The wind transducer mounts at the masthead and connects through the supplied 30 m mast cable to the Smart Wind wired gateway. The gateway then connects into the vessel network using the included SeaTalk NG to DeviceNet adaptor cable. The SeaTalk NG backbone should be protected by a 5 A fuse.

When installed with compatible Raymarine displays, the sensor data can be used for wind, speed, true wind, and sailing performance calculations. This makes it a strong fit for cruising sailboats and performance-focused boats that already use Raymarine instruments or Axiom chartplotters.

Dimensions and environment

The wind transducer measures 657.762 mm long including cable, 540.712 mm long excluding cable, 46.96 mm wide, and 305.86 mm high. The wired gateway measures 155.61 mm long, 47.38 mm wide, and 30.61 mm high, so it can be mounted in a protected service area with access to the network backbone.

The masthead sensor is rated for 100% relative humidity, while the below-deck gateway is rated up to 93% relative humidity at 40°C. Storage temperature range is -30°C to +70°C, which helps cover seasonal layup and harsh cabin or locker temperatures.
