Marine VHF Radio

Having a handheld or fixed-mount VHF radio onboard is a must for most every type of boater. Whether you need to contact marinas, other vessels, or emergency services, having a VHF radio ensures you're connected when it matters most. Models with GPS-enabled DSC (Digital Selective Calling) add an extra layer of safety by allowing you to send your location during distress situations.

Who can benefit: Handheld VHF radios are ideal for kayaks, inflatable dinghies, and small runabouts. Larger boats benefit from fixed-mount VHFs which offer extended range, owing to the height of their antennas.

Dedicated Fishfinder

If fishing is part of your boating routine, a fishfinder is a must-have. These compact devices use sonar technology to identify underwater structures and locate fish. Despite their small size and relatively low cost, a small dedicated fishfinder can pack a punch with advanced features like CHIRP and down- and side-scan imaging, offering excellent performance and value for anglers.

GARMIN STRIKER Plus 4 Fishfinder with Dual-Beam CHIRP Transducer

Who can benefit: The small size of dedicated fishfinders makes them a great choice for kayaks, inflatable dinghies, and small runabouts, where space and simplicity are key. Owners of these small craft can enjoy enhanced fishing experiences without the need for larger, more expensive systems.

Fishfinder/Chartplotter Combo

Fishfinder/GPS chartplotter combos combine advanced fishfinder technology (CHIRP, side scan, down scan, etc.) with detailed marine maps for real-time location tracking and route planning. These dual-purpose devices not only help anglers locate fish but also provide essential navigation features for any boater. With a single unit, you can monitor the underwater environment while ensuring you stay on course, making these a versatile and space-saving option. Advanced models often include features like 3D mapping and auto-routing, further enhancing functionality and convenience.

Who can benefit: Most any boat used for fishing, provided it has enough space at the helm, is a good candidate for a fishfinder/chartplotter combo.

Radar

Radar is an invaluable tool for boaters who navigate in low-visibility conditions, such as fog, heavy rain, or at night. Coastal and offshore boats can all benefit from radar which can detect nearby vessels, landmasses, and obstacles, enhancing situational awareness and collision avoidance.

Who can benefit: Small offshore fishing boats, large offshore fishing boats, cruising sailboats and motor yachts can all benefit from the increased safety and situational awareness that radar provides.

Multi-Function Packages

If you have a larger boat and value integration and efficiency, an MFD can be a game-changer. These devices display information from multiple systems—GPS, radar, sonar, and AIS—into one interface. With available inputs, they can also be used for monitoring engine data, video boat surveillance, remote steering, and more. They’re ideal for larger vessels or those with more complex navigation needs, streamlining control and data access in one sleek unit. Tip: If you are planning on adding radar to your boat, consider a multi-function package, like what you see below, which combines radar with a multi-function display.

GARMIN GPSMAP® 1243xsv Multifunction Display with Navionics+ US Coastal and Inland Charts and GMR 18 HD3 Radar Bundle

Who can benefit: Large offshore fishing boats, motor yachts and cruising sailboats with multiple systems onboard can benefit significantly from the integration capabilities of MFDs, making them ideal for enhancing navigation and control.

AIS (Automatic Identification System)

AIS provides information about nearby vessels, such as position, speed, and course, helping you avoid potential collisions. This system is especially useful in crowded waterways or during night passages, complementing radar to give you a comprehensive picture of your surroundings. For serious cruisers, it’s a worthwhile investment. Note: To view AIS information on your boat, you'll need an AIS receiver or transceiver (Class A or B) and a compatible display unit like a chartplotter, multi-function display, or AIS screen. Additionally, a VHF antenna or antenna splitter is required to transmit and receive AIS signals.

Who can benefit: Small offshore fishing boats, large offshore fishing boats, and cruising sailboats operating in busy waterways or near major shipping lanes can use AIS to enhance safety and situational awareness.

EPIRB or PLB (Emergency Position Indicating Radio Beacon or Personal Locator Beacon)

Safety is paramount on the water, and an EPIRB or PLB can be a lifesaver. An EPIRB is registered to your vessel and transmits its location during distress situations, while a PLB is registered to an individual and offers similar functionality. Offshore boaters should consider these devices essential, but even coastal cruisers can benefit from the added safety.

Who can benefit: PLBs are ideal for small boats, kayaks, inflatable dinghies, and individual boaters, offering personal emergency signaling for nearshore activities or when space is limited. EPIRBs, on the other hand, are better suited for larger vessels such as offshore fishing boats, cruising sailboats, and motor yachts, providing vessel-specific distress signaling for extended voyages and open-water use.

Marine Instruments

Marine instruments provide critical data like wind speed, depth, water temperature, and boat speed. These tools are especially useful for sailors and serious cruisers who rely on precise environmental and navigational information. High-quality marine instruments can integrate with other electronics, enhancing your boat’s overall systems. Examples include wind meters, depth sounders, and speed logs that contribute to safer and more efficient navigation.

Who can benefit: Sailboats, racing yachts, and performance cruisers can benefit from instrument systems that provide the information they need for safe navigation and for optimizing sailing performance.

Starlink For Boats

For boaters who want reliable internet connectivity on the water, Starlink's satellite-based system offers a revolutionary solution. With global coverage, even in remote offshore locations, Starlink provides high-speed, low latency internet suitable for navigation updates, weather reports, streaming, and staying in touch with loved ones.

STARLINK Flat High-Performance Antenna (Router Not Included)

Who can benefit: Cruising sailboats, offshore fishing boats, motor yachts and liveaboard vessels with demanding communication needs will find Starlink invaluable for connectivity and convenience.

Conclusion

The right boating electronics can transform your time on the water, making every trip safer, more productive, and more enjoyable. Whether you need a basic fishfinder for a kayak or a full electronics suite for a large, offshore motor yacht, there’s gear to match your boating style and goals. Take a moment to evaluate your setup and identify where the right upgrades can make a difference. With the right tools in place, you’ll be ready to navigate confidently and make the most of every adventure.
