Navigating busy waterways demands reliability and visibility, especially when conditions turn challenging. The Simrad RS40-B stands out as a fixed-mount VHF radio that combines powerful communication with advanced situational awareness. Its built-in Class B AIS transceiver not only tracks nearby vessels but also broadcasts your position, ensuring you're visible to others in fog, darkness, or high-traffic zones. Paired with the included GPS-500 antenna, it delivers precise location data to enhance every trip, whether you're cruising coastal waters or exploring inland routes.
Class B AIS sets this radio apart for recreational and smaller commercial boats. Unlike receive-only systems, the RS40-B actively transmits your vessel's data—position, speed, course, and MMSI—using efficient SOTDMA or CS-TDMA protocols to minimize interference. Receive AIS signals from larger ships equipped with Class A systems, overlaying targets directly on the radio's display or sending data via NMEA 2000 to your chartplotter for a unified view.
Real-world mariners report fewer close calls in marinas and shipping lanes, crediting AIS for that extra layer of confidence during night passages or reduced visibility.
The clever removable fist mic transforms installation challenges into simple solutions. Connect it to the front panel for compact setups or the rear with extension cables for overhead mounts—no dangling wires to snag gear. At just 7.92 inches wide and 3.85 inches high when flush-mounted, it fits tight consoles without dominating space.
Expand functionality with up to two optional wireless handsets. Place one at the helm, another in the cabin or cockpit—these HS40 units mirror the main display and controls, perfect for larger boats. They even enable intercom mode for crew coordination without shouting over engine noise.
Cover all international, Canadian, US, and WX channels with selectable 25W or 1W output for versatile range control. Class D Digital Selective Calling (DSC) automates distress signals, position sharing, and individual calls, approved for safety worldwide. Built-in GPS ensures accurate coordinates without external reliance, though the GPS-500 boosts reception in obstructed areas like canyons or under hardtops.
Plug into NMEA 0183 or NMEA 2000 networks to share GPS, AIS, and VHF data across your electronics suite. Sync with autopilots for waypoint navigation, radars for ARPA-like tracking, or apps via Wi-Fi gateways. This connectivity future-proofs your boat, letting data flow from radio to dashboard effortlessly.

Stay safer on the water with this VHF marine radio featuring a Class B AIS transceiver, and built-in GPS. See and be seen by nearby AIS-equipped vessels thanks to an integrated Class B AIS transceiver, and add up to two optional wireless handsets to stay connected from anywhere on board. Bundled with GPS-500 for enhanced GPS performance. See and Be Seen with Integrated AIS: The RS40-B features a Class B AIS transceiver, which not only receives AIS targets but also transmits your boat's position to nearby AIS-equipped vessels. This helps other mariners to spot your boat through any conditions, day or night. A built-in AIS receiver monitors the position of other AIS-equipped vessels, helping you to proactively avoid collisions in crowded harbors and waterways. AIS information can be viewed on the radio’s built-in screen, or overlaid on your chart or radar screen through a compatible multifunction display. Removable Fist Mic: The RS40-B's removable fist mic can be connected to the front or rear of the radio, and optional extension cables allow the mic and radio to be mounted separately. This offers a simple and cost-effective solution for any mounting location, with no cable clutter. For example, the RS40-B can be mounted overhead, with no hanging cables, while the mic is connected to an extension socket on the dash below.
