The Raymarine i40 Wind offers small-boat sailors vital wind information in a convenient, compact format. The instrument displays apparent wind speed (e.g., in knots) and the direction from which the wind is blowing relative to the boat’s bow, via a clear pointer or digital indicator. If connected to the onboard system (e.g., through SeaTalk to a network with a speed sensor), the i40 Wind can compute and show true wind speed/angle as well, accounting for the boat’s motion. With its extremely low power draw, the unit is suitable for small boats where electrical power is at a premium – you can leave it on throughout your sail without worry. The i40 Wind also has the valuable ability to work in tandem with an autopilot: by providing its data into the SeaTalk network, it enables the autopilot to hold a course relative to the wind, which is especially handy when sailing single-handed or on long legs where you want the boat to maintain a set wind angle automatically. Installation of the instrument is straightforward – it can be flush-mounted on a bulkhead or installed on a bracket, and the display’s large numbers and symbols are easy to see. In summary, the i40 Wind is a "small but mighty" tool that enhances the safety and comfort of sailing on smaller yachts, delivering wind information akin to larger systems.
- Recommended for small sailing yachts and sport boats (up to ~33 ft) that need basic yet reliable wind data without the complexity of larger systems
- Excellent instrument for training and recreational sailing – helps the crew understand and react to wind changes, even on boats with minimal electronics
- Allows integration into existing SeaTalk networks on older boats – for example, it can replace or supplement an old wind gauge while remaining compatible with other equipment onboard
- Often used as an economical wind measurement solution – operates standalone with its included wind vane sensor (Rotavecta) or as a repeater for a larger yacht’s main system (e.g., at a second helm station or on a tender)
