Raymarine i40 Wind Display System w/Rotavecta Transducer

Enhance Your Boating with Precise Wind Data

Imagine gliding across open water, confidently trimming sails or adjusting throttle based on real-time wind insights. The Raymarine i40 Wind Display System, paired with the reliable Rotavecta transducer, delivers exactly that. This compact powerhouse mounts neatly on your helm, providing crystal-clear readings of apparent and true wind speed and direction—essential for sailors honing their skills or powerboaters navigating tricky gusts.

Crafted for smaller vessels like RIBs, day sailers, and weekend cruisers, it stands out with its oversized 28mm digits on a sharp segmented LCD. Whether you're racing competitively or leisurely exploring, the red backlighting ensures visibility from dawn patrols to midnight runs, cutting through fog, spray, or twilight haze.

Standout Features for Everyday Seamanship

• Analog-Style Virtual Needle: Instant wind direction at a glance, mimicking traditional gauges but with digital precision.
• Dual Wind Modes: Switch seamlessly between apparent wind (what you feel) and true wind (actual conditions), unlocking optimal performance when linked with speed and compass data.
• Customizable High-Wind Alarm: Get alerted to sudden squalls, helping you reef sails proactively or seek shelter.
• Ultra-Low Power Draw: Sips just 25mA at 12V, extending battery life on long passages without compromising reliability.
• Built-In Transducer Ready: The Rotavecta masthead unit—a lightweight 3-cup anemometer—connects directly, simplifying setup over generic sensors.
• Rugged Build: IPX6 waterproofing shrugs off heavy downpours, with a -20°C to +55°C operating range for all-season adventures.

Three intuitive buttons handle it all: no fumbling with complex menus mid-maneuver. Plus, the sleek design blends with Raymarine's aXs, C, and E-Series multifunction displays, creating a unified helm aesthetic.

Seamless Integration into Your Marine Setup

SeaTalk networking is the secret sauce here. Plug into your existing Raymarine autopilot or chartplotter, and watch data flow effortlessly—repeat wind info across displays or feed it to auto-trim functions for hands-free wind-angle sailing. It's backward-compatible with older ST40 footprints, easing upgrades on legacy boats.

Dimensions are helm-friendly at about 5 inches wide, 2.8 inches tall, and 1.4 inches deep, with included surface-mount hardware and a protective sun cover. For dash cuts, the optional trunnion kit offers flexibility without permanent mods.

Practical Tips for Peak Performance

Mount the Rotavecta high on your mast, away from rigging shadows, for unerring accuracy up to 100 knots. Calibrate for your boat's heel angle to fine-tune true wind calculations—sailors swear by this for tactical edges in club races. Low power means it's ideal for solar setups on offshore tenders, and the dimmable backlight prevents night blindness while preserving battery.

Users rave about its stability in chop: no fluttering readings like cheaper vane sensors. Pair it with an i40 Speed or BiData for a full environmental picture, turning your console into a pro-level station without the bulk.
