Overview

The B&G BGH030006 is a 36 m (118 ft) mast cable for B&G vertical arm masthead units. It runs between the wind sensor at the masthead and the rest of your B&G instrument system, carrying wind data down the rig without needing splices or extensions.

A 36 m length suits taller masts and gives room for clean routing through the spar, a deck gland, and a proper service loop at the mast base. It also makes sense as a like-for-like replacement when an older cable has been chafed inside the mast or damaged during a de-mast.

Key features

• 36 m (118 ft) cable length for full mast runs on taller rigs
• Intended for B&G vertical arm masthead units (VMHU-style wind sensors)
• Single continuous run to avoid extra joins that can create intermittent readings
• Extra length to allow for tidy routing, strain relief, and service loops at the mast base

Compatibility and fit

This cable is meant for B&G vertical arm masthead units. Before ordering, confirm your masthead sensor style and that your existing cable is the dedicated mast cable for that unit, not a network backbone or a standard drop cable.

For fit, plan the full path from the masthead to the instrument entry point, including any internal conduits, exit holes, deck glands, and the slack needed at the mast step for stepping and unstepping the mast.

Installation and setup

Most installs are easiest with the mast down, using a messenger line to pull the cable through the spar. Inside the mast, protect the run anywhere it could rub on rivets, sharp cutouts, or halyards, and leave enough slack so the cable is not supporting its own weight at the masthead connection.

At the deck or cabin entry, use a proper gland or boot and route the cable so water does not track along it into the boat. If you are reusing an existing passage, check that the bend is gentle and that the cable is not forced through a tight radius.

Use cases on board

This is a good match for cruising and performance sailboats that rely on a vertical arm wind sensor and need a full-length replacement cable during a re-rig, mast service, or instrument refit. It is also useful when mast height or routing changes leave the original cable too short to dress and secure correctly.

Maintenance and care

After installation, recheck the cable at the mast base and any exit points after a few sails to confirm it is not moving, chafing, or pulling under load. Periodically inspect the run where it passes through deck hardware and keep the connector area clean and dry during service work to reduce corrosion-related connection issues.
