Overview

The Raymarine T137 is a single mast bracket for Micronet displays and Race Master sailing instruments. It is the T137 slug mast bracket, a 1-up mounting option for Digital, Dual, Analog and Master range displays where a clean mast-mounted instrument position is needed.

This bracket gives sailors a practical way to keep key data visible from the cockpit or rail, especially on race boats and performance cruising sailboats where mast-mounted displays are easier to read at a glance. The black powder-coated finish keeps the installation looking tidy against most mast sections, while the corrosion-free construction suits exposed deck and rigging areas.

Key features

• Single 1-up mast bracket for one compatible Raymarine Micronet or Race Master display.
• Fits Raymarine T110 Digital Display, T111 Dual Digital Display, T112 Analog Display, T070 Race Master and T075 Race Master System.
• Black powder-coated finish for a low-glare look on deck and at the mast.
• Corrosion-free construction for use in exposed marine mounting locations.
• Strong structure with low weight, useful where extra weight on the mast should be kept down.
• Fixed mast mounting position helps keep sailing instrument data visible while trimming, helming or moving around the cockpit.

Compatibility and fit

The T137 is intended for Raymarine Micronet displays and Race Master instruments rather than general-purpose chartplotters or GPS displays. It is a good match when replacing a worn bracket, adding a single mast display, or standardizing an older Micronet or Race Master installation.

Before fitting, confirm that the display model matches the supported Raymarine instrument range and that the mast location gives clear visibility without interfering with halyards, reefing lines, sail covers or other deck hardware.

Installation and use on board

This is a fixed mast bracket, so placement matters. Install it where the display can be read from the helm and working cockpit positions, while still leaving room for sail handling and mast work. On racing boats, that usually means a position that keeps performance data in view during trimming and maneuvers.

As with any mast-mounted electronics hardware, check the mounting area, fasteners and display attachment periodically. Salt, vibration and repeated rig movement can loosen hardware over time, so routine inspection helps keep the instrument secure through coastal sailing, club racing and longer passages.

Materials and care

The black powder-coated surface should be rinsed with fresh water after heavy salt exposure and cleaned with mild soap when needed. Avoid abrasive cleaners around the bracket and nearby display housing, since they can mark the finish and make future cleaning harder.
