Enhance Your On-Water Safety with Advanced AIS Integration
Navigating busy waterways or foggy conditions demands more than just a standard VHF radio. The Simrad RS40-B stands out by combining robust communication with a built-in Class B AIS transceiver and GPS receiver. This setup lets you broadcast your vessel’s position while receiving real-time data from nearby AIS-equipped boats, creating a clearer picture of potential hazards. Whether you’re dodging traffic in a congested marina or crossing shipping lanes at dusk, this radio turns reactive hailing into proactive awareness.
Imagine threading through a fleet of fishing boats at dawn—your position pings on their screens, and theirs appear on yours, reducing guesswork and close calls. The large, sunlight-readable display ensures you can glance and react without fumbling, even with wet hands after a sudden squall.
Flexible Mounting and Control Options for Any Vessel
Installation headaches? Not here. The clever removable fist microphone connects to the front or rear, with optional extension cables letting you tuck the main unit overhead while keeping the mic handy at the helm. No dangling wires to snag gear or distract during maneuvers. Its compact footprint—about 8 inches wide and under 4 inches high when flush-mounted—fits seamlessly on consoles, bulkheads, or even tight flybridge setups.
For larger boats, pair it with up to two wireless handsets. These HS40 companions mirror the full display and controls, perfect for checking channels from the bow while reeling in a catch or coordinating with crew in the cabin. They even transform the system into an onboard intercom, streamlining shouts across decks.
Power Through Channels and Emergencies with Confidence
Class D Digital Selective Calling (DSC) approval means instant distress signals with your GPS coordinates, alerting rescuers precisely where you need them. Switch between 25 watts for long-range punch and 1 watt for local chatter, covering all international, USA, Canadian, and weather (WX) channels complete with alerts for incoming storms.
The 30-watt hailer blasts commands over foghorns or bridges, or hook up an external speaker for cabin-wide announcements. NMEA 0183 and NMEA 2000 connectivity overlays AIS data onto your chartplotter or radar, integrating effortlessly into modern Simrad networks for a unified helm experience.
Practical Tips for Seamless Setup and Daily Use
Start by securing the flush mount or bracket in a spot with clear antenna line-of-sight—higher is better for range. Power it via 12-24V DC, and wire NMEA drop cables for data sharing. Test AIS transmission post-install by verifying your MMSI on a buddy’s display. For handsets, charge them fully before first use to ensure reliable roaming range up to 30 meters line-of-sight.
Daily, scan WX channels during offshore runs; the auto-alert chimes cut through engine noise. In crowded anchorages, toggle AIS to SOTDMA mode for priority updates if traffic thickens, keeping you visible amid the chaos.
