Garmin quatix 7 Marine GPS Smartwatch

The quatix 7 is a premium marine GPS smartwatch designed for sailors who want a compact, weatherproof navigator on the wrist. Its always-on 1.3-inch display remains legible in bright sun, and a stainless steel bezel plus QuickFit band system deliver rugged durability for saltwater environments. Traditional physical buttons complement a responsive touchscreen, enabling quick access to settings even while wearing gloves. Onboard, the device pairs with compatible Garmin chartplotters and supports remote control of key MFD features, including chart zoom, layout shortcuts, Fusion stereo, autopilot, and other connected marine devices. This integration streamlines cockpit operation and lets you stay on course with minimal head-down time.
For sailing-specific convenience, the quatix 7 includes tide change awareness, anchor drag alerts, and waypoint marking, which help crews monitor evolving conditions and maintain optimal positions. The wearable form factor ensures continuous position tracking, course plotting, and notifications during long passages orshore visits. Battery life supports extended watch duty, and the device’s rugged construction is designed to withstand spray and immersion typical of small- to mid-sized sailboats. While it excels as a cockpit companion, it also serves as an independent navigation and safety tool when away from fixed instruments.
Retevis RM40 Marine Radio With GPS

The RM40 is a compact marine handheld radio with integrated GPS for precise position sharing and navigation support on the water. It provides real-time GPS-position updates, which enhances situational awareness during close-quarters maneuvering or offshore transit. A key safety feature is the DSC distress call capability, which enables preset distress messages and automatic transmission of your GPS coordinates to nearby vessels and the coast guard. The MOB (Man Overboard) alarm records and shares exact overboard locations via GPS, improving rescue coordination. NOAA weather alerts keep crews informed of evolving marine conditions.
Designed for boats, the RM40’s waterproofing and rugged construction support operation in spray and rain. Its GPS-enabled location sharing works in tandem with DSC functions to improve safety responses, particularly during night operations or rough seas. Users can store preset channels and zones for regional sailing routes, while the radio’s international channels capability helps crews communicate with nearby vessels and port authorities. The RM40 is best used as a dedicated safety-and-communication tool to complement more advanced chartplotters and navigational displays aboard bigger boats.
Garmin eTrex 22x Handheld GPS

The eTrex 22x is a rugged handheld GPS device well suited for sailors who want a dependable backup navigator in a palm-sized form. It features a 2.2-inch sunlight-readable color display designed for readability in bright sun and high glare conditions common at sea. Preloaded Topo Active maps provide routable roads and trails, which can be helpful for shore excursions and inland legs of a voyage. The device’s durable construction and straightforward interface make it a practical companion for sailors who need quick waypoint setup, reliable positioning, and offline navigation when chartplotters are unavailable.
With a focus on clarity and simplicity, the eTrex 22x offers essential navigation tools without overwhelming menus. It supports offline map regions, which can be valuable during coastal passages where signal access is intermittent. While it isn’t a full marine chartplotter, its ruggedness, long battery life, and easy-to-use interface make it a reliable back-up or secondary navigation source on deck or onshore. Sailors who value portability and independent GPS capability will find the 22x to be a practical addition to their navigation toolkit.
Garmin eTrex 32x Handheld GPS

The eTrex 32x expands on the eTrex family with a similar 2.2-inch display and rugged handheld design, offering dependable navigation in challenging marine environments. It comes preloaded with Topo Active maps featuring routable roads and trails for outdoor activities, including hiking and coastal excursions that sailors may pursue when ashore. The 32x provides reliable GPS positioning, waypoint management, and a straightforward user interface, making it a practical companion for sailors who want a durable, independent device for landings, port calls, and backup navigation on the water.
In marine contexts, the 32x supports quick waypoint creation, trip logging, and easy data transfer to other devices, which helps crews coordinate coastal routes with pre-planned shore visits. While it does not replace a dedicated marine chartplotter, its portability and reliable GPS accuracy complement onboard electronics, offering an affordable, rugged solution for sailors who need a durable backup navigator during all stages of a voyage.
QEDASS GPS Navigator 7 Inch

The QEDASS GPS Navigator 7-inch model is a large, user-friendly car and truck navigation device that can also function as a practical land-based planning tool for sailors during port visits or coastal shore trips. It ships with free lifetime map updates, including up-to-date North American maps, which helps keep routes current through multiple sailing seasons. The device employs a bright 7-inch touchscreen, a substantial battery, and ample storage (16GB ROM with 256MB RAM, expandable memory) to support offline maps and route planning. It offers multiple route options (Fast, Green, Short, Easy) and functionalities such as speed camera alerts and turn-by-turn guidance, which can be beneficial for inland excursions and docking maneuvers when ashore.
Although primarily marketed for land-based navigation, the QEDASS navigator serves as a versatile supplement to marine gear. It provides reliable route planning, live speed data, and time estimates that help sailors plan itineraries around harbor arrivals and fuel stops. Its broader map coverage and large display can assist in pre-departure planning, weather checks, and port-finding activities. For sailors who want a cost-effective, portable navigation option beyond dedicated marine devices, the QEDASS 7-inch navigator offers useful features and value.
Buying Guide: Key Considerations For Choosing A Sailing GPS
- Marine-grade durability and water resistance: Look for devices with IP ratings or MIL-STD-style ruggedness. Saltwater and spray are common, so corrosion resistance and sealed housings matter for longevity.
- Display readability and size: Sunlight glare, screen brightness, and contrast influence readability on deck. Larger screens are easier to use while actively steering, but you may prioritize compact wearables for convenience.
- Navigation data type and maps: Decide between marine charts, topographic maps, or a combination. Preloaded Topo Active maps are helpful for shore excursions, while marine charts are essential for offshore navigation.
- Power and battery life: Watches and handhelds differ in how long they run between charges. Consider battery life for long passages, and whether devices support external power or quick-swaps.
- Integration with other gear: Chartplotter and MFD compatibility, DSC safety features, MOB alerts, and autopilot control are valuable for cohesive navigation and safety on boats with multiple devices.
- Safety features: DSC distress calls, MOB alarms, NOAA weather updates, and tide/anchor alert capabilities significantly affect risk management on the water.
- Maps updates and coverage: Lifetime or regular map updates improve route accuracy over time. Check whether updates cover regions you sail most often (coastal zones, harbors, or offshore routes).
- Portability vs. fixed gear: Handhelds and watches offer portability and redundancy, while fixed chartplotters provide comprehensive onboard navigation. A layered approach often yields the best results.
- Price and total cost of ownership: Consider initial cost, optional map updates, and accessories (chargers, mounts, and cables) when evaluating value.
