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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eReplacement windvane and anemometer cup set for Raymarine ST50, ST60, and ST80 masthead transducers.\u003c\/li\u003e\n\u003cli\u003eHelps restore wind direction and wind speed sensing when the original masthead vane or cups are damaged or worn.\u003c\/li\u003e\n\u003cli\u003eIncludes the directional feather and counterweight used for the wind direction side of the transducer.\u003c\/li\u003e\n\u003cli\u003eIncludes replacement speed cups for the anemometer side of the masthead unit.\u003c\/li\u003e\n\u003cli\u003eSet screws and an allen key wrench are included for securing the replacement parts during installation.\u003c\/li\u003e\n\u003cli\u003eUseful for sailboats that rely on Raymarine legacy wind instruments for trim decisions, watchkeeping, and cockpit wind data.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003cp\u003eOnce 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.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eDirectional feather\u003c\/li\u003e\n\u003cli\u003eCounterweight\u003c\/li\u003e\n\u003cli\u003eSpeed cups\u003c\/li\u003e\n\u003cli\u003eSet screws\u003c\/li\u003e\n\u003cli\u003eAllen key wrench\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Raymarine","offers":[{"title":"Default Title","offer_id":52023830872245,"sku":"QBP950582","price":29.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1331132_qbp950582.webp?v=1780192025","url":"https:\/\/www.qualityboatparts.com\/products\/qbp950582","provider":"Quality Boat Parts","version":"1.0","type":"link"}
