Raymarine Micronet Race Master Wireless Instrument System

Overview

The Raymarine Race Master Wireless System is a solar powered wireless tactical race compass range for sailboat racing, with compass-only and system configurations available for 868 MHz or 916 MHz wireless regions. It gives the helm and crew a clear view of heading, wind shift, lift and header information, line bias, and race timer functions from a dual LCD display that can be read from either side of the boat.

This range fits racing sailors who want useful tactical data without running instrument cables through the hull or down the mast. The Race Master can work as a standalone compass, while the system versions add hull data through a T910 through-hull depth, speed, and temperature triducer and a T121 hull transmitter.

Key features

• Wireless Micronet instrument platform reduces cabling work during installation and keeps the cockpit or mast area cleaner.
• Solar powered Race Master display supports long use on deck without a routine charging step.
• Two high-contrast LCD displays are angled for viewing from both sides of the boat while racing.
• Integrated heading sensor supports race-focused functions including RaceTimer, Wind Shift, and Line Bias.
• Bar graph display can show analog-style information for wind shift, speed trim, or depth when the system is configured with compatible data sources.
• Available in 868 MHz versions for Europe and 916 MHz versions for the Americas, Asia, and Australasia.
• System configurations can add depth, speed, and temperature data using the included T910 through-hull triducer and T121 hull transmitter.
• Compatible with the T113 Wireless Remote Control for onboard control away from the display location.

Variants

The Race Master Wireless System is offered in compass-only and expanded system configurations. The main differences are the wireless frequency and whether the package includes the hull data components used for speed, depth, and temperature.

The 868 MHz variants are for Europe, while the 916 MHz variants are for the Americas, Asia, and Australasia. The compass variants center on the Race Master display itself, while the system variants add through-hull sensor and transmitter hardware for a more complete racing instrument setup.

• T070-916: Compass configuration with 916 MHz wireless frequency. This version suits boats in 916 MHz regions that need the Race Master compass and tactical display functions without the added hull data package.
• T070-868: Compass configuration with 868 MHz wireless frequency. This version suits boats in European 868 MHz regions that need the Race Master compass and tactical display functions without the added hull data package.
• T074-868: System configuration with triducer and solar panel, using 868 MHz wireless frequency. This version includes the T910 through-hull depth, speed, and temperature triducer with flush mount fitting, the T121 hull transmitter, and the T138 external solar panel for the hull transmitter.
• T074-916: System configuration with triducer, using 916 MHz wireless frequency. This version includes the T910 through-hull depth, speed, and temperature triducer with flush mount fitting and the T121 hull transmitter for adding hull data to the Race Master setup.

Installation and setup

The wireless layout is useful on race boats where keeping weight, cable runs, and deck clutter under control matters. The compass display can be positioned for cockpit visibility, and the system versions add through-hull hardware for boats that also need speed, depth, and water temperature data in the instrument network.

For the system versions, installation planning should include the through-hull triducer location, hull transmitter placement, and the correct wireless frequency for the sailing region. The T074-868 configuration also includes an external solar panel for powering the hull transmitter, which should be placed where it can receive useful light during normal use.

Use cases on board

This range is a strong match for dinghy, keelboat, and club racing crews who want tactical compass information at a glance during starts, upwind legs, and downwind gybes. The display helps the crew track shifts, compare heading against the mean course, and judge line bias without relying on a handheld compass or a wired cockpit display.

The system configurations are better suited to boats that need Race Master functions along with hull-based speed and depth data. The compass-only configurations keep the setup simpler for boats that only need heading and tactical race information.
