Overview

The B&G 213-10-056 is a replacement wind vane for the 608 masthead unit (MHU) wind sensor, used to bring wind direction readings back to normal when the original vane is damaged or missing. It replaces the vane moulding that the sensor uses to track wind direction, which helps steady apparent wind angle and the wind calculations your instruments depend on.

This vane fits the B&G 213, 496, 508, 608, and VMHU wind sensors. It is the wind vane component only, and it does not replace wind cups, bearings, or the electronics inside the masthead unit.

This part is a good match for sailors keeping a legacy B&G masthead sensor in service on a cruising boat or a race boat, especially when the rest of the sensor is still in good shape and only the vane needs attention.

Key features

• Replacement vane moulding for B&G 213, 496, 508, 608, and VMHU masthead wind sensors
• Restores wind direction sensing when the original vane is bent, cracked, or missing
• Replaces the wind vane only; wind cups and bearing assemblies are serviced separately
• Small spare part that stores easily on board for masthead repairs

Compatibility and fit

Confirm the model of your masthead wind sensor before ordering. This vane is used across several B&G sensor families, including the 608 MHU, and it is intended to match the vane mounting used on the 213, 496, 508, 608, and VMHU sensors.

If your wind sensor is giving unstable direction data, inspect the vane and its mounting for cracks, UV damage, or impact marks. If the vane moves freely but the readings still jump or stick, the issue may be in the direction bearing assembly rather than the vane itself.

Installation and checks

Replacing a masthead vane is typically a short job once you have safe access aloft. Secure small parts with a lanyard, and make sure the vane can swing without rubbing on the sensor body after it is fitted.

After installation, verify that the vane rotates smoothly through a full sweep and that the display tracks direction changes consistently. Depending on your instrument setup, you may want to confirm alignment and calibration settings after the physical repair.

Maintenance and care

The masthead is a harsh spot for any exposed component, so regular visual checks help. Rinse salt spray when practical, and look for signs of cracking or looseness during routine rig inspections, especially after heavy weather or mast work.
