E22078 Short Arm Vane Transmitter for i60/iTC-5/ST60+/ST60

The E22078 Short Arm Vane is Raymarine’s standard masthead anemometer/vane designed to mount atop the mast of sailing vessels. Its short arm (~300 mm) makes it suitable for boats where longer wind sensors aren’t necessary – for example, vessels up to about 12–15 m in length, or whenever reduced sensor motion and vibration are desired. This unit accurately captures wind direction using a lightweight vane and measures wind speed via a spinning cup assembly (anemometer cups).

• Precise wind readings: The Short Arm wind vane provides instant information on the angle of the wind relative to the boat’s bow, as well as the wind speed in knots. Its sensitive wind vane arrow responds even to slight breezes, and the three-cup anemometer ensures smooth rotation regardless of wind direction. This is crucial for proper sail trim and tactical decisions during races.
• Rugged marine-grade construction: The sensor is built to withstand continuous exposure to the elements – intense sun, salt spray, vibrations, and even bird strikes. The arm and vane are made of lightweight yet durable materials (aluminum and reinforced plastic) which ensure balance and minimal weight, reducing strain on the masthead. The rotating mechanism features low-friction bearings, guaranteeing long life and accuracy.
• Easy system integration: The E22078 Short Arm Vane comes with a 30 m (98 ft) cable that runs down the mast to connect into your system. For classic ST60/ST60+ Wind displays, the connection is direct (analog input). For newer i60 displays, the signal is fed through an ITC-5 converter, which translates the analog data into SeaTalkNG digital format. Once connected, the sensor immediately provides wind data that can be viewed on a dedicated wind instrument and utilized by the autopilot or multi-function displays.
• Optimal size for standard yachts: With its ~30 cm arm, this sensor strikes a balance between sensitivity and sturdiness. The short arm means less swaying in a pitching mast and lower risk of snagging on overhangs (e.g., during transport or winter storage). It delivers the accurate wind information needed for safe and efficient sailing without the complications that can come with longer sensors.

The E22078 Short Arm Vane is a proven choice for most cruising and racing yachts equipped with Raymarine wind instruments. Its combination of reliability, easy compatibility, and straightforward installation makes it a favored component when upgrading or replacing existing wind vanes. With this sensor, you’ll have a continuous “eyes on the wind” – absolutely vital for any journey under sail.
