Overview

The Raymarine A28162 is a 30 m masthead cable assembly with base for Raymarine wind instrument installations using ST60 and i70 displays.

It is used to run the masthead wind transducer connection from the top of the mast down to the instrument system, giving the installer 30 m, or 98.4 ft, of cable for routing through the mast and onward to the display or wind interface. For many sailboats, this is the cable and base assembly needed when replacing a worn masthead connection, refreshing an older ST60 wind setup, or supporting an i70 wind display installation.

The base is part of the assembly, so the masthead connection point can be renewed at the same time as the cable. That matters on boats where the existing cable has seen years of movement, moisture, UV exposure near the masthead, or service work during a rig pull.

Key features

• 30 m, or 98.4 ft, cable length for routing from the masthead down through the mast and toward the instrument system.
• Includes the masthead base as part of the cable assembly, useful when renewing the connection point at the top of the rig.
• Made for Raymarine ST60 and i70 wind instrument installations, helping maintain a correct fit within those systems.
• Supports masthead wind transducer installations where wind speed and direction data need a clean connection from the sensor location to the helm display system.
• Suited to service work during a rig pull, mast rewiring, wind transducer replacement, or troubleshooting of an aging masthead cable run.

Installation and setup

Plan the cable route before the masthead base is fitted. On most sailboats, the cable is routed inside the mast where it is protected from deck traffic and line handling, with attention paid to chafe points, sharp exits, and movement at spreaders or mast fittings.

A drip loop should be considered where the cable exits or enters enclosed areas, so moisture is less likely to follow the cable directly into a connector or instrument space. Any unused cable length should be managed neatly rather than left loose inside the rig, where it can slap, rub, or become difficult to service later.

Compatibility and fit

This assembly is intended for Raymarine masthead wind installations associated with ST60 and i70 instrument systems. Before ordering, check the existing wind transducer, display setup, and cable path on the vessel, especially on refits where older ST60 equipment may have been mixed with newer instruments or interface modules.

The 30 m length is a practical fit for many mast installations, but the required run depends on mast height, deck exit location, service loops, and the route from the mast base to the instrument area. Measuring the existing run or the planned route is the safest way to confirm length before the mast is stepped.

Use cases on board

This cable and base assembly is a good match for owners maintaining Raymarine wind instruments on cruising sailboats, club racers, and refit projects where the masthead connection needs to be replaced rather than patched. It is also useful when intermittent wind readings point to a tired cable run, corrosion at the masthead base, or damage found during rig service.
