Raymarine Masthead Only Wind Arm Vane & Cups – R28170

The Raymarine Masthead Only Wind Arm Vane & Cups (R28170) is a marine-grade wind speed and direction sensor designed to mount at your vessel’s masthead to accurately capture apparent wind data underway or at anchor. It includes the wind vane, rotating cups, and standard mounting arm, but does not include cables — making it ideal as a replacement for existing installations on compatible Raymarine systems.
