LCJ CV7-C-RM-STBG rotating mast wind system
LCJ CV7-C-RM-STBG combines the CV7-C ultrasonic wind-sensor configuration with an STBG rotating-mast interface for compatible Raymarine and B&G wind systems. It is intended where movement of the mast needs to be taken into account before wind direction is presented to the vessel instruments. F&C Marine can help confirm the sensor, mast-angle source, interface and existing equipment before supply.
Ultrasonic wind measurement and mast rotation
The CV7 family measures airflow electronically without conventional rotating cups or a mechanical vane. The sensor’s directional reference still moves with a rotating mast, so accurate mast-angle information is required to correct the result to the vessel reference. The sensor also needs clean airflow and correct physical alignment. Nearby rigging, aerials and mast structures should have the least practical influence on the measuring area.
STBG instrument integration
The STBG configuration is intended for specified compatible Raymarine and B&G equipment. Before ordering, record the exact wind displays, instrument servers and any existing converters. Photograph the present rotating-mast interface and wiring where possible. Mixed-generation equipment and previous alterations are common on refitted vessels, so the complete signal path should be confirmed rather than assuming that brand compatibility alone is enough.
Mast-angle, power and cable installation
The sensor, mast-angle source and interface all require reliable electrical and data connections. Install and calibrate the mast-angle equipment according to manufacturer documentation and protect cables from chafe, repeated movement and water ingress. Areas close to a rotating mast deserve particular attention because wiring may be exposed to continual flexing. Label raw wind, mast-angle and corrected-output connections so future service engineers can understand the system without tracing every conductor.
Commissioning corrected wind direction
After fitting, check wind speed and corrected direction through a useful range of mast positions. Compare physical mast angle with the value used by the interface and verify that displayed wind direction remains consistent as the mast moves. Where practical, test under realistic sailing conditions. Compare data across connected displays and record the sensor orientation, mast reference, interface model and calibration settings for future maintenance.
Maintenance and fault finding
If the corrected wind direction becomes unreliable, test the installation in stages. Confirm the wind sensor, mast-angle source, interface power and wiring and receiving instruments separately. A failed or miscalibrated angle source can make a healthy wind sensor appear wrong. Inspect cables around moving areas for wear and corrosion and compare current settings with the commissioning record before changing components.

Before ordering LCJ CV7-C-RM-STBG
Send the vessel type, rotating-mast details, current wind sensor, mast-angle equipment, exact Raymarine or B&G instrument models, photographs and wiring information. If replacing a fault, include symptoms and tests already completed. F&C Marine can then help confirm whether LCJ CV7-C-RM-STBG is the correct configuration and identify any additional interface, mounting or installation requirements before quotation.
