Raymarine i50 Speed Display System

Upgrade your boating experience with the Raymarine i50 Speed Display, a compact powerhouse designed for sailors and powerboaters who demand precise speed data at a glance. Whether you're racing competitively, cruising coastal waters, or navigating open seas, this instrument delivers essential metrics like speed through water, GPS speed over ground, velocity made good (VMG), average and maximum speeds, trip logs, distance logs, and sea surface temperature. It even includes practical timers—a count-up timer plus two race-start timers—to keep you on pace during regattas.

Why Boaters Trust the i50 Speed for Reliable Performance

Crafted with Raymarine's renowned engineering, the i50 Speed stands out in harsh marine environments thanks to its IPX6 waterproof rating and rugged construction. The oversized digits on the high-contrast LCD ensure readability from wide angles, day or night, while the red backlighting minimizes eye strain during evening passages. Low power draw—under 1W as a repeater—makes it ideal for battery-conscious setups on smaller vessels like RIBs, yachts, or sailboats.

What sets it apart from basic gauges? Seamless networking flexibility. Connect directly to a speed transducer or use it as a repeater pulling data from your existing SeaTalkng backbone, NMEA2000 systems, or even legacy SeaTalk setups. This modularity lets you expand your helm without rewiring everything, integrating effortlessly with Raymarine autopilots, multifunction displays like the Axiom series, or i70 color instruments for a cohesive dashboard.

Key Features That Enhance Every Voyage

• Comprehensive Speed Insights: Track through-water speed, SOG (with GPS input), VMG for upwind/downwind optimization, averages, peaks, logs, and temp—all switchable via intuitive keypad controls.
• Superior Visibility: Extra-large numerals, anti-glare LCD, and adjustable red night backlighting with local or group dimming.
• Versatile Connectivity: Built-in transducer port, dual SeaTalkng ports; adaptable to NMEA2000 and SeaTalk1 for hybrid systems.
• Compact and Tough: Slim 110mm x 115mm footprint matches ST60+ cutouts; surface or optional trunnion mount; survives -20°C to +55°C operations.
• Efficient Power: 12V DC operation, minimal consumption even with transducer (max 200mA).

Effortless Integration and Customization

Install it as a standalone master unit with its own paddlewheel transducer for direct speed and temp readings, or network multiple i50 Speed displays as repeaters for redundancy across the cockpit. Pair it with i50 Depth or Tridata for a full analog-style suite that complements modern MFDs. The front-mount design simplifies retrofits, and silicone sun covers protect against UV exposure. Boaters often praise how it eliminates data conflicts by prioritizing multiple sources intelligently, ensuring accurate info when it matters most—like fine-tuning sail trim or monitoring fuel efficiency via SOG.

Pro tip from seasoned installers: Calibrate your transducer offset for hull deadrise to get pinpoint accuracy, especially in choppy conditions where through-water speed trumps GPS for true performance metrics.
