B&G VMHU Mast Cable - 36m

Enhance Your Sailing Instrumentation with Reliable Masthead Connectivity

Navigating challenging waters demands precision from every component on your vessel. The VMHU Mast Cable steps in as a critical link, delivering uninterrupted data from your masthead sensors to the cockpit displays. Spanning a generous length, this cable accommodates taller masts common on performance yachts and cruising boats, ensuring wind speed, direction, and other vital readings flow seamlessly without signal loss or interference.

Crafted for the harsh marine environment, it resists saltwater corrosion, UV exposure, and constant flexing from mast movement. Sailors trust this setup for consistent performance during long passages, races, or casual outings, minimizing downtime and maximizing data accuracy that informs every sail trim decision.

Key Features Tailored for Serious Sailors

• Extended Reach: Ideal for masts requiring substantial cable runs, providing flexibility without splicing or makeshift extensions.
• Vertical Arm Compatibility: Specifically engineered for B&G vertical arm masthead units, guaranteeing a secure, plug-and-play fit.
• Shielded Construction: Protects against electromagnetic interference from onboard electronics, delivering clean NMEA 0183 or 2000 signals.
• Durable Marine-Grade Materials: Waterproof connectors and rugged outer jacket withstand years of exposure to wind, rain, and spray.
• Easy Routing: Slim profile slips neatly through mast conduits, reducing installation headaches.

Why Upgrade Your Mast Cable Matters for Performance Sailing

A subpar cable can introduce noise into your wind data, leading to erratic readings that throw off your polar diagrams or autopilot adjustments. This specialized cable eliminates those risks, supporting B&G's ecosystem of instruments like Triton displays or Zeus chartplotters. Whether retrofitting an older setup or building a new race boat rig, it ensures your masthead anemometer or vane performs at peak efficiency.

Boat owners report fewer sensor recalibrations and sharper response times after installation, translating to better boat speed and safer maneuvers in gusty conditions. Pair it with proper masthead unit alignment for optimal airflow readings that give you the edge over competitors.

Practical Installation Insights for DIY Enthusiasts

Start by powering down all electronics. Disconnect the old cable at both ends, noting connector orientations. Feed the new cable from the masthead down through the existing path, securing with cable ties every meter to prevent chafing. At the deck gland, apply marine sealant for a watertight seal. Test continuity with a multimeter before finalizing connections at the network hub.

Pro tip: Label ends clearly for future access, and consider adding inline strain relief where the cable exits the mast base. This straightforward swap typically takes under two hours, restoring full functionality without specialist tools.

Long-Term Maintenance for Peak Reliability

Inspect annually for frays or connector corrosion, especially after offshore trips. Rinse with fresh water post-sail to flush salt buildup. If signal issues arise, check for kinks rather than assuming sensor failure—often, it's the cable taking the brunt of mast vibes.
