Raymarine RCU-1 Wireless Autopilot Remote: A Game-Changer for Shorthanded Sailors

Raymarine has finally cut the cord on autopilot remotes with the new RCU-1, a wireless control unit for the Evolution autopilot range scheduled for Q2 2026 release. At $549.99 for the starter kit, it lands in a sweet spot between Raymarine's existing wired remotes and the more elaborate watch-style controllers from competitors. For shorthanded offshore sailors, the headline feature isn't the convenience of remote steering — it's the integrated solo-sailor MOB safety mode.

What's in the Box

The starter kit ships with one RCU-1 fob, a charging dock, and a wireless gateway that plugs into the existing SeaTalk-NG backbone. Range is rated at 98 feet, which covers the working length of any production cruising boat under 50 feet and most cockpit-to-foredeck use cases on bigger yachts. The fob is IPX7 rated, runs on a rechargeable lithium cell, and weighs less than three ounces — light enough to clip to a PFD harness without being annoying.

Controls are deliberately simple: course-up and course-down rocker, mode toggle (auto, standby, wind, track), tack button, and the dedicated MOB trigger under a hinged guard. The hinged guard is the right choice; nobody wants to accidentally drop the autopilot into MOB mode while reaching for a halyard.

The Real Innovation: Solo MOB Mode

Here's what makes the RCU-1 interesting for bluewater sailors. When a single-handed sailor goes overboard wearing the fob, the loss of wireless signal triggers the autopilot to immediately bear away, drop the chute (if a Raymarine actuator is configured), and broadcast an MOB alert via the network — sounding the chartplotter alarm, dropping a waypoint, and if connected, transmitting a DSC alert via VHF.

The fob itself starts flashing a high-intensity strobe and emitting a 90-decibel signal once it hits saltwater. For solo passagemakers, this addresses the single biggest fear of offshore sailing: falling off the back of the boat with the autopilot dutifully steering away into the night. Whether the boat actually returns to you is a separate question — the RCU-1 doesn't have a return-to-MOB autonomous function — but the alert chain it triggers is significantly more robust than what most cruisers currently run.

Compatibility and Installation

The RCU-1 works with all Evolution autopilot computers (EV-100, EV-150, EV-200, EV-400) running firmware 4.7 or later. The wireless gateway connects via a single SeaTalk-NG backbone tap and draws negligible power. Installation should take any reasonably handy owner about an hour, mostly spent finding a dry, central location for the gateway antenna.

If your boat runs an older SPX or S-series autopilot, you're out of luck — Raymarine has not back-ported support, and the underlying CAN-bus messaging is different. An Evolution upgrade is roughly $1,800 plus installation, which puts the total cost of getting RCU-1 functionality on an older boat closer to $2,400.

What's Missing

A few notable omissions. There's no charting or position display on the fob, so you cannot use it as a true secondary helm station the way you can with B&G's H5000 wireless or the Garmin Reactor remote. There's no return-to-MOB autonomous behavior. And the fob doesn't talk to non-Raymarine multifunction displays, so Garmin or Furuno-equipped boats won't see the alerts on their plotters.

Verdict

For Raymarine-equipped cruisers running Evolution pilots, the RCU-1 is an easy upgrade and the solo MOB feature alone justifies the price for shorthanded sailors. For mixed-electronics boats or those running older Raymarine pilots, the value proposition is weaker. Pre-orders open through Raymarine dealers in May, with first shipments expected in late June.
