Raymarine 30' Seatalk Cable ST-50 Style

Extend your marine electronics network with confidence using this robust 30-foot SeaTalk cable, designed in the classic ST-50 style for seamless integration into Raymarine systems. Perfect for boaters who need reliable connectivity across larger cockpits or between helm stations, this cable bridges the gap between instruments without signal loss or interruptions, keeping your navigation data flowing smoothly even in rough seas.

Built for the Demands of the Water

Crafted with marine-grade materials, this cable withstands saltwater exposure, UV rays, and constant vibration—common challenges on any vessel. The twisted-pair construction minimizes electromagnetic interference, ensuring clear communication between your depth sounders, wind instruments, and autopilots. At 30 feet, it offers ample reach for multi-station setups, from sailboats to power yachts, without the bulk of shorter extensions requiring daisy-chaining.

Effortless Compatibility with Raymarine Gear

This ST-50 style cable mates perfectly with legacy and newer Raymarine components that use the SeaTalk protocol. Think ST50 series displays, tiller pilots, and smart transducers—it's the go-to link for expanding older systems or tying in modern upgrades. The proprietary 3-pin connectors snap in securely, supporting both power and bidirectional data over a single run, simplifying your wiring harness.

• Precise Fit: ST-50 compatible plugs for plug-and-play installation.
• Extended Reach: 30 feet of flexible, low-profile cabling.
• Reference: Matches Raymarine D131 specifications for authenticity.
• Rugged Sheathing: TPE jacket resists abrasion and chemicals.

Real-World Benefits for Skippers and Crew

Imagine glancing at your wind data from the flybridge while your autopilot holds course below— this cable makes it possible without compromising accuracy. Boaters report fewer glitches during long passages, thanks to its shielded design that blocks out engine noise and radio interference. It's not just wire; it's the backbone of a responsive helm that responds to your every command, enhancing safety and enjoyment on the water.

For DIY installers, routing is straightforward: strip the ends only if splicing, secure with cable ties away from heat sources, and test continuity with a multimeter. Pro tip: Pair it with inline fuses for added protection against shorts in wet bilges.

Long-Lasting Performance Tips

To maximize lifespan, avoid sharp bends under 2-inch radius and coil loosely when stowed. Regular inspections for chafe points near bulkheads keep it performing season after season. Unlike generic alternatives, this cable's quality construction means no frequent replacements, saving time and hassle during critical voyages.

Equip your boat with connectivity that lasts—reliable, versatile, and ready for adventure.
