advanSea Wind-a S400 Analog Complete System — Precision Wind at a Glance

The advanSea Wind-a S400 Analog Complete System brings advanced wind sensing into a compact, rugged package that sailors can rely on in any condition. With a 360° analog wind-direction display paired with a wide-angle digital readout, you get fast, unambiguous weather insight at a glance—perfect for cruising days, club racing, or offshore passages.

Why this system stands out

• 360° wind direction in an instant: A full-circle analog dial keeps you oriented no matter where the wind shifts, even when glare, spray, or rain are high.
• Clear, wide-angle LCD: A transflective monochrome display provides a large, legible digital readout in bright sun or dim cockpit lighting, ensuring you don’t miss critical gusts or changes.
• Precise wind metrics: Measures wind speed from 0–199 knots with 1-degree directional resolution, capturing subtle shifts that can affect sail trim and course.
• Contextual wind data: View apparent wind angle and speed alongside true wind metrics and velocity made good (VMG) to optimize sail selection and real-time routing.
• Wind trend indicators: Visual cues show whether wind is rising or falling, helping you anticipate shifts and adjust sails proactively.
• Safety and reliability: Wind-speed alarms and a low-battery alert keep you informed as conditions evolve or power wanes.
• Flexible integration: Stand-alone operation or NMEA0183 compatibility with intelligent transducers (Airmar or Plastimo) for seamless chartplotter and instrument network integration.
• Durable, legible design: IP66 front seal, anti-fog coating, and backlit amber keys deliver dependable visibility in spray, heat, or nighttime conditions.
• Efficient power use: Low current draw ensures this instrument stays reliable on long passages where power is precious.
• Ready-to-install package: Supplied as a complete masthead system with 25 m cable, designed for quick mounting on most sailboats; it can also function as a display-only unit to expand an existing setup.
• Peace of mind with support: Two-year warranty and global assistance through the Plastimo network mean confident voyaging.

Whether you’re chasing a race-driven position, cruising for comfort, or navigating offshore legs, the Wind-a S400 translates complex wind data into actionable, real-world decisions. Trim smarter, steer with certainty, and sail with clarity—day or night, in calm seas or gusty squalls.

Ideal use scenarios

Dockside daysailers and weekend cruisers will appreciate the simplicity of a single, integrated wind readout that still provides the depth of data needed for precise sail trim. Competitive sailors gain a reliable means to monitor wind shifts, optimize VMG, and adjust tactics on the fly. Offshore crews benefit from a robust, easy-to-read instrument that performs in challenging environments and maintains readability when spray and sun are intense.

How it helps you sail better

The Wind-a S400’s combination of 360° directional clarity, high-contrast digital readouts, and contextual wind metrics gives you a practical edge. By understanding both apparent and true wind, plus VMG and wind trends, you can time main and jib adjustments more accurately, choose foils and sail plans that suit current conditions, and set a course that consistently aligns with your performance goals or comfort thresholds.

Practical tips for best results

• Install the masthead unit where it’s shielded from direct spray but exposed to prevailing wind to capture representative conditions.
• Pair the Wind-a S400 with compatible transducers and chartplotters to unlock integrated navigation views and synchronized data across your cockpit instruments.
• Route the 25 m cable with minimal sharp bends to preserve signal integrity and minimize voltage drop on long installs.
• Take a baseline reading in steady seas to compare apparent wind with known boat speed, helping you fine-tune sail trim and heading for optimal VMG.

Brand assurance: Advansea combines tested marine electronics engineering with practical sailing insight, delivering instruments that excel in real-world conditions. The Wind-a S400 is built to endure spray, heat, and long voyages while remaining easy to interpret, day or night.
