Garmin Mast Cable - 40M (131')
Garmin Mast Cable - 40M (131') Product Description
Enhance your sailing setup with the robust extension cable designed specifically for Garmin's gWind and gWind Race wind transducers. Stretching an impressive 131 feet (40 meters), this black 6-pin mast cable delivers reliable connectivity from your masthead sensor down to your chartplotter or display unit. Sailors trust it for seamless data transmission in harsh marine environments, ensuring accurate wind speed and direction readings even on taller masts or complex rigging setups.
Why Sailors Choose This Mast Extension Cable
Unlike standard cables that falter under constant exposure to salt spray, UV rays, and vibration, this purpose-built extension maintains signal integrity over long distances. It eliminates the hassle of splicing wires or dealing with unreliable adapters, providing a clean, professional installation that withstands the rigors of offshore racing or coastal cruising.
- Precision Engineering: 6-pin design ensures full compatibility and zero data loss for gWind transducers.
- Durability First: Marine-grade construction resists corrosion and abrasion, ideal for mast runs.
- Flexible Routing: Slim profile navigates tight spaces around spreaders and halyards effortlessly.
- Peace of Mind: Backed by Garmin's commitment to quality, with a focus on longevity in wet, windy conditions.
Perfect Fit for Your Garmin Ecosystem
This cable pairs flawlessly with gWind™ and gWind Race models, extending reach without compromising performance. Whether you're upgrading a compact daysailer or outfitting a bluewater cruiser, it integrates smoothly into NMEA 2000 networks for real-time wind data on multifunction displays.
Quick Installation Tips for Optimal Performance
- Secure the cable along the mast with UV-resistant ties, avoiding sharp bends near the transducer base.
- Route through existing conduits or aft stays to minimize windage and chafe points.
- Connect to your Garmin marine network hub—plug-and-play simplicity means you're sailing sooner.
- Test connections offshore: Verify wind angles and speeds match visual cues for calibration confidence.
Pro tip: Pair with dielectric grease on connectors to fend off moisture ingress during prolonged exposure.
Elevate Your On-Water Experience
Imagine tacking through a fleet with pinpoint apparent wind data feeding your autopilot and tactician's tablet. This extension cable turns raw sensor signals into actionable insights, helping skippers optimize sail trim, plot perfect laylines, and shave minutes off race times. Cruisers benefit too, with reliable inputs for weather routing and safe passage planning amid shifting breezes.
Its length accommodates superyacht masts or multi-spreader rigs, where shorter cables fall short. Boaters report fewer dropouts and truer readings compared to generic extensions, making it a staple for regatta pros and weekend warriors alike.
Long-Term Reliability and Care
To maximize lifespan, inspect the cable annually for frays or saltwater buildup. Rinse with fresh water after every outing, and store coiled loosely during layups. This simple routine keeps connections crisp season after season, supporting Garmin's reputation for gear that endures.
