Overview

The Raymarine T210 is a solar-powered Micronet wireless Maxi display for performance sailing and racing yachts. It gives the crew a large mast-mounted readout without running instrument cables through the mast or hull, with 50 mm digits that are easy to read from the cockpit, rail, or working deck.

This display is built around Raymarine’s Micronet wireless instrument system, so it can show sailing and navigation data from the onboard network while keeping installation lighter and cleaner than a wired mast display. It uses solar charging with an internal lithium battery and can run for up to 300 hours in daylight operation, with night operation supported by selectable red or amber backlighting.

The unit weighs 365 g and is made for exposed sailing use, including spray, rain, and wet deck conditions. It operates from -10° to +60°C and uses 868 MHz or 916 MHz wireless frequency, depending on the regional version.

Key features

• Micronet wireless data display reduces the need to route instrument wiring through the mast or hull.
• Large 50 mm digits help the helm, tactician, and trimmers read key numbers from a distance.
• Solar power with internal battery support gives up to 300 hours of autonomy in normal daylight use.
• Three backlight levels with red or amber options support night sailing while limiting glare.
• Auto Leg function can show different data pages for different stages of a race course.
• Page hiding lets crews keep only the useful pages in rotation, reducing button presses during racing or short-handed sailing.
• Start Line, Line Bias, Wind Shift, Race Timer, Set, Drift, Turn, and Course to Steer functions support tactical sailing and tidal decision-making.
• Remote configuration and control are supported through a compatible Raymarine Wireless Remote Display.
• Sealed waterproof construction is rated for submersion to 10 m, useful for exposed mast and deck mounting.
• Audible alarms can be used for depth, wind, cross track error, and waypoint arrival when supported by the connected system.

Installation and setup

The wireless layout is a major advantage on racing yachts, especially when adding a mast display to an existing boat. With no instrument cable to chase down the mast, installation is cleaner and there is less weight aloft. The display is commonly used where the crew needs a clear readout from multiple positions, such as the mast, cockpit, or companionway area.

Configuration is handled through the Micronet system. A compatible Raymarine Wireless Remote Display is required for full setup and calibration, while the single control button on the Maxi display gives limited local control. For a boat with several mast displays, each unit can be set up to show different pages so the crew is not looking at duplicated information.

Display and race functions

The high-contrast LCD is intended for quick reading under changing light, from bright daylight to night watches. At night, the black display background and selectable red or amber digits help keep the numbers visible without flooding the cockpit with light.

For racing crews, the display is especially useful when timing starts, tracking wind shifts, and managing course legs. Auto Leg can change the displayed information as the boat moves through the race sequence, while page hiding keeps the data set focused so the crew can move through pages faster.

Marine use and maintenance

This display is a good match for sailors who want mast-visible data with minimal wiring work, including club racers, offshore race boats, and performance cruising boats already using a Raymarine Micronet wireless instrument network. It is not a standalone sensor; it relies on compatible network data sources for speed, wind, depth, heading, navigation, and alarm information.

For storage over winter or long idle periods, the internal battery should be charged in natural daylight before the display is put away. Artificial light should not be used for charging. Keeping the solar area clean and the display free of salt buildup helps maintain charging performance and screen readability.
