Raymarine Masthead Cable and Base, For R28170 and R28171 Mastheads, 50m

Overview

The Raymarine A28163 is a 50 m masthead cable and base for Raymarine R28170 and R28171 mastheads. It is made for wind instrument installations where the cable run needs to travel from the masthead down through the spar and into the vessel’s instrument system.

At 50 m, or about 164 ft, this cable suits taller masts and longer routing paths where a shorter lead would not reach cleanly. It is a practical replacement part when the original masthead cable is damaged, has aged, or needs to be renewed during mast work, rig refit, or wind transducer service.

Key features

• 50 m cable length gives enough reach for masthead-to-display routing on many sailboat installations.
• Compatible with Raymarine R28170 and R28171 mastheads.
• Supplied with the masthead base, so the cable and base connection can be replaced together.
• Supports wind instrument signal routing from the masthead position to the vessel’s Raymarine instrument setup.
• Useful for service work during mast removal, rigging updates, or replacement of an older masthead cable.

Installation and fit

Before ordering, match the masthead model on the boat to the R28170 or R28171 reference and confirm that a 50 m run is appropriate for the mast height and routing path. This is not a general-purpose network cable, so fit should be checked against the wind transducer hardware rather than only by length.

During installation, route the cable where it is protected from chafe, sharp turns, and compression inside the mast. Leave a practical service loop at accessible points, especially near the mast base, so future rigging work can be handled without putting strain on the cable.

Use on board

This cable is a good match for sailboats using compatible Raymarine masthead wind hardware, particularly when restoring wind data after cable damage or replacing parts during a refit. It helps keep the wind sensor connection consistent from the top of the mast to the instrument system used at the helm or navigation station.
