For coastal navigation, a reliable marine GPS chart plotter helps you plot courses, mark waypoints, and read charts with confidence. This guide highlights five top options, explaining who they’re best for and why they fit different needs—from rugged handhelds to large-screen chartplotters. Whether you’re a recreational sailor, fisherman, or professional navigator, use the quick comparison table to pick the right model before you buy.
| Product | Best For | Why It Stands Out |
|---|---|---|
| Fauitay 10.4 Inch Marine GPS Chart Plotter | Owners needing a large display | Bright TFT LCD, high resolution, dual chart options, world simplified chart for global use |
| Garmin GPSMAP 86Sci | Handheld GPS on deck or shore | Floating, rugged, preloaded BlueChart G3, satellite compatibility, expandable memory |
| Raymarine Element 7 HV | Integrated helm plotter with fast rendering | Quad-core performance, Lighthouse North America charts, simple controls |
| Weems & Plath Parallel Plotter | Traditional chart plotting on deck | Durable acrylic and aluminum roller, precise distance scales |
| Weems & Plath ParaLock Plotter | Compact deck plotting tool with locking feature | Sturdy acrylic, locking knob for chart stability |
Fauitay 10.4 Inch Marine GPS Chart Plotter
The Fauitay 10.4 Inch Marine GPS Chart Plotter targets users needing a large, high-contrast display for on-water navigation. Best for sailors who want a color LCD with clear visibility in bright sunlight. Features include a 10.4-inch TFT LCD display at 800 x 600 resolution and a built-in dual chart option. It also supports a world simplified chart and a local chart via storage card. The device uses a GNSS receiver for location accuracy and offers a floating ground design for stability on rough seas. A potential limitation is that detailed local charts may require separate chart purchases for fully detailed coastal navigation.
Who it’s best for: Coastal cruisers and open-water sailors who benefit from a larger display and flexible chart options. If you prefer a single, ready-to-use screen with global coverage and an option to add detailed local charts, this model is a strong pick.
Garmin GPSMAP 86Sci, Floating Handheld
The Garmin GPSMAP 86Sci is a rugged, floating handheld with preloaded BlueChart G3 coastal charts and a bright, sunlight-readable display. It’s designed for open-boat handling and shore-to-ship transitions, providing reliable navigation in remote areas where a fixed plotter isn’t practical. It supports multiple satellite constellations for robust tracking, and its water resistance makes it suitable for marine environments. A potential limitation is its smaller 3-inch display compared to larger chartplotters, which may require zooming or magnification for detail in rough seas.
Who it’s best for: Boaters who need a portable, float-ready unit to carry on deck or in a pocket-chart approach, and those who want robust satellite coverage and memory for thousands of waypoints and routes.
Raymarine Element 7 HV
The Raymarine Element 7 HV offers a compact, fast-operating chart plotter with a 7-inch display and Chirp Sonar. The unit features a dedicated keypad and a large waypoint key, enabling quick mark-and-go actions on the water. With Lighthouse North America charts included, it provides reliable coastal and inland coverage for the US and Canada. This model is best for helm-integrated setups requiring quick access and straightforward navigation. A caution is that some advanced sonar or transducer options require additional purchases beyond the base package.
Who it’s best for: Small to mid-sized boatsers who want a responsive, user-friendly interface with reliable regional charts and straightforward operation at the helm.
Weems & Plath Parallel Plotter
The Weems & Plath Parallel Plotter is a traditional, durable chart plotting tool designed for deck use. Its acrylic construction mounted on a marine-grade aluminum roller ensures chart visibility and durability in harsh marine environments. It includes distance scales at 1:20,000, 1:40,000, and 1:80,000 to fit various U.S. Coast and Harbor Charts, with inch and nautical mile scales for precise plotting. Best for sailors who prefer manual plotting alongside or instead of digital displays. A limitation is that it does not provide digital navigation data or automatic chart updates.
Who it’s best for: Traditional navigators who rely on paper charts and need a precise, stable tool for manual plotting and distance measurement.
Weems & Plath ParaLock Plotter
The ParaLock Plotter offers a compact, locking mechanism to keep charts steady during plotting. It uses clear acrylic with a locking knob to secure chart positions and improve accuracy when transferring bearings or course lines. Best for sailors who value stability on deck during plotting sessions and want a tool that reduces chart movement. A potential limitation is that it may not have the large scale options of some parallel plotters, requiring careful handling for very long course lines.
Buying Guide: Key Considerations for Choosing a Marine GPS Chart Plotter
- Display size and readability: Larger displays are easier to read in bright sunlight, but consider mounting space and helm visibility.
- Chart coverage: Ensure the plots offer BlueChart, Navionics, or equivalent coastal charts for your cruising area; verify compatibility with your vessel’s needs.
- Floating vs fixed: Handheld or handheld-capable units provide portability; fixed plotters stay mounted at the helm for constant access.
- Connectivity: Look for supports for NMEA, sonar, and data integration with other instruments or chartplotters.
- Chart updates and storage: Consider built-in memory, chart update frequency, and options to insert SD cards or use cloud updates.
- Durability and water resistance: Choose devices with appropriate IP ratings or floating capabilities for on-water reliability.
- Manual plotting vs digital plotting: Manual tools (like parallel plotters) complement digital plots, especially on older charts or in restricted digital environments.
FAQ
- What is the difference between a chart plotter and a handheld GPS for marine use?
Answer: A chart plotter is designed for continuous onboard navigation with marine charts and often integrates with other systems; a handheld GPS is portable and may be used as a backup or for onshore navigation. - Do marine plotters require internet connectivity?
Answer: Many rely on preloaded charts or local storage; some models support updates via internet or connected devices. - Are paper plotters still useful on modern boats?
Answer: Yes, as a backup or for traditional chart plotting, especially when digital systems are unavailable or for training. - Can I use different chart formats on the same plotter?
Answer: Some plotters support multiple chart formats (e.g., BlueChart and Navionics) depending on model and region. - Is a floating handheld GPS sufficient for open-water navigation?
Answer: It can be a reliable backup and for quick location check, but for primary navigation, a dedicated chart plotter or integrated system is recommended.
