Imagine gliding through open waters with a seamless panoramic view of your charts, wind data, and navigation tools—all without the clutter of bezels interrupting your focus. The B&G Zeus S 12″ 3012UW Ultrawide chartplotter redefines how sailors interact with their helm station. Its expansive SolarMAX IPS touchscreen stretches your data across a breathtaking 1920 x 720 resolution, making split-screen layouts feel natural and effortless. Whether you’re plotting a coastal cruise or fine-tuning tactics mid-race, this unit pulls you deeper into the experience, turning raw data into intuitive decisions.
Sailors often struggle with cramped displays that force constant zooming and scrolling. Here, the ultrawide format shines by accommodating full SailSteer overlays alongside laylines, course-up radar, and instrument readouts simultaneously. It’s not just bigger—it’s smarter, with modes tailored to cruising relaxation, high-stakes racing, or secure anchoring.
Award-Winning Sailing Tools at Your Fingertips
What sets this chartplotter apart for serious sailors? Dive into features born from real-world racing feedback. SailSteer visualizes your optimal path with wind shifts in mind, while dynamic laylines adjust to true wind angles, helping you nail tacks and gybes. Race modes activate StartLine tools for precise timing and RacePanel for wind calls—essentials for club races or offshore campaigns.
Cruising Mode: Simplified dashboards with weather overlays and anchor alarm zones for worry-free day sails.
Racing Mode: Instant access to polar-matched routes, heading/lift indicators, and virtual start lines.
Anchoring Mode: Swing radius predictions and depth alarms to protect your boat at low tide.
Pair it with B&G wind sensors for live true wind data that feeds into autopilot adjustments, keeping you on the optimal angle without constant helm tweaks.
Next-Level Charting with C-MAP X-Gen Precision
Navigation demands clarity, and the integrated C-MAP DISCOVER X charts (North America coverage) deliver stunning detail—from shaded bathymetry to custom shading for reefs and ledges. Zoom seamlessly across vast areas or drill into harbors with high-res local intel. Night mode preserves your vision during overnight passages, while Safety Alerts ping hazards like shallows or uncharted rocks before they become problems.
Upgrade to REVEAL X for satellite overlays that blend real-world imagery with vector charts, ideal for unfamiliar anchorages. The onboard X-Chart Manager is a game-changer: select regions for instant wireless updates, no laptop required. Keep your charts evolving with seasonal depth changes and new buoy placements.
Seamless Boat-Wide Networking
This isn’t a standalone screen—it’s the nerve center of your vessel. NMEA 2000 connectivity links Triton instruments, Nemesis dashes, and Hercules processors for unified data flow. Ethernet ports hook up HALO radars for pulse-compression clarity in fog or traffic. Add IP cameras for 360-degree situational awareness, or stream SiriusXM weather in U.S. waters.
Wi-Fi and Bluetooth open wireless control via the B&G app, letting crew check charts from below deck. A 12-month premium app subscription sweetens the deal upon chart registration, unlocking advanced planning tools onshore.
Rugged Build for Harsh Marine Conditions
Engineered to thrive where others falter: IPX6/IPX7 waterproofing shrugs off spray and submersion, while 1000+ nits brightness cuts through direct sun—even with polarized lenses. Operating from -15°C to 55°C ensures reliability from tropics to high latitudes. Vibration-tested to 20G, it’s race-ready for choppy seas.
