B&G WS740S Vertical Wind Sensor - 1800 mm

The WS740S Ocean Spec wind transducer features a 1.8-meter high-modulus carbon mast designed to position the vane in undisturbed airflow and minimize disturbances. Its one-piece vane design, developed over more than 200,000 hours, ensures high aerodynamics and stability for precise wind measurement, particularly suited to racing sailboats and demanding cruising.

The WS740S Ocean Spec wind sensor is supplied with a 1800 mm (1.8 m) carbon mast.

The WS740S wind sensor can connect directly to B&G H5000 or WTP3 systems.

The WS740S transducer transmits NMEA 0183 MWV,R sentences at a 10 Hz frequency.

Yes, the WS740S sensor can integrate with NMEA 2000® systems. A NMEA 0183 to NMEA 2000® gateway is required for this integration, as the sensor outputs in NMEA 0183.

The one-piece design of the WS740S wind transducer, resulting from extensive wind tunnel testing, ensures superior aerodynamics and stability. This enables extremely precise measurement of wind angle and speed, essential for optimal sailing performance and autopilot reliability.

Yes, the WS740S sensor is fitted with a high-modulus carbon mast of "Ocean Spec" type, designed to provide increased robustness and durability suitable for harsh marine environments and competitive racing.

The 1800 mm mast length allows positioning the sensor’s wind transducer/vane anemometer in the least disturbed airflow. This minimizes interference from the sail plan or mast, ensuring more accurate and reliable true wind measurement.

The WS740S Ocean Spec wind transducer is primarily designed for racing sailboats and demanding cruising where wind data accuracy and reliability are critical for performance and safety.

Installing the WS740S sensor requires a suitable mast mount. The sensor is designed to be mounted at the masthead to optimize wind measurement. Specific mounts (such as the BGH030008 listed in the documentation for a masthead mount) are typically used for secure attachment.

A masthead bracket such as the BGH030008, compatible with the WS740S, weighs 160 g (0.35 lbs).

The BGH030008 mast bracket is made of HS 30 aluminum with a hard black anodized finish.

The product is described as the "vertical wind sensor only". Although a connection cable is required for its operation, the provided information does not specify whether it is included or must be purchased separately. It is advisable to check the exact list of items included in the packaging.

The BGH030008 mast mount is black.

Like any marine electronic instrument, the WS740S sensor requires a power supply. It is designed to be powered by the system it is connected to (B&G H5000, WTP3, or via an NMEA 2000® gateway), which typically provides a standard 12V DC supply for marine equipment.

The accuracy of the wind angle and speed data provided by the WS740S wind sensor is critical for the autopilot. Reliable wind data enables the autopilot to maintain a more precise course relative to the wind, optimize sail trim, and improve overall sailing efficiency.

Yes, the WS740S sensor is "Ocean Spec" rated and designed for racing sailing and demanding cruising. Its high-modulus carbon mast and robust design make it suitable for harsh marine environments.

The WS740S wind transducer must be mounted at the masthead. This elevated position, combined with its 1.8-meter mast length, ensures the vane anemometer captures wind in an undisturbed airflow, free from interference by sails or the boat's structure, thereby guaranteeing optimal measurements.

Yes, the WS740S Ocean Spec Vertical Wind Sensor is a B&G product, known for its marine navigation instruments.

For racing navigation, accurate wind data (angle and speed) is fundamental. It enables sailors to make informed decisions about sail changes, helm adjustments, and race strategies, leading to more reliable race calls and better overall performance.
