Raymarine Anemometer Cups and Feather Kit, For ST50 ST60 ST80 Masthead Transducers

Overview

The Raymarine E28081 is a replacement windvane and anemometer cup set for Raymarine ST50, ST60, and ST80 masthead transducers. It replaces the moving wind-sensing parts at the masthead, helping the instrument system read wind direction and wind speed again when the original vane or cups are worn, damaged, or missing.

This is a small but important service item for boats that depend on apparent wind data for sailing trim, route planning, autopilot use, and general awareness in changing conditions. The kit includes the directional feather, counterweight, speed cups, set screws, and an allen key wrench, so the main replacement pieces needed for this repair are in the package.

Key features

• Replacement windvane and anemometer cup set for Raymarine ST50, ST60, and ST80 masthead transducers.
• Helps restore wind direction and wind speed sensing when the original masthead vane or cups are damaged or worn.
• Includes the directional feather and counterweight used for the wind direction side of the transducer.
• Includes replacement speed cups for the anemometer side of the masthead unit.
• Set screws and an allen key wrench are included for securing the replacement parts during installation.
• Useful for sailboats that rely on Raymarine legacy wind instruments for trim decisions, watchkeeping, and cockpit wind data.

Installation and fit

This set is intended for compatible Raymarine masthead wind transducers in the ST50, ST60, and ST80 instrument families. Before ordering, check the masthead unit on the boat and confirm that the existing wind sensor matches one of those systems, especially on vessels with older or mixed instrument installations.

Installation is typically done at the masthead, so plan for safe access before starting the job. The replacement cups and vane should move freely after fitting, and the set screws should be tightened securely without forcing the small parts out of alignment.

Use on board

This replacement set is a practical match for sailboat owners maintaining a Raymarine legacy wind system rather than replacing the full instrument package. It is especially useful after storm damage, UV aging, bird strikes, rig work, or any service where the exposed wind sensor parts at the masthead have been disturbed.

Once installed, the wind instrument system should be checked from the display to confirm that wind speed and wind angle respond normally before relying on the readings underway.
