Buying Guide – How to Choose the Best GPS for Sailing

Selecting the right navigational tool involves balancing screen size, battery endurance, and specific marine features.

Display Quality and Size

A high-resolution display is critical for reading charts clearly in bright sunlight. Larger screens offer more detail for navigation but require more mounting space.

Prioritize sunlight-readable screens to ensure safety and visibility during active sailing conditions.

Satellite Support

Modern GPS devices support multiple constellations like GPS, GLONASS, and Galileo to maintain signal strength in areas with obstructed skies. This ensures you stay on course even near cliffs or large structures.

Look for multi-constellation support to guarantee reliable tracking wherever you sail around the world.

Battery Endurance

Battery life varies significantly between handhelds and fixed units. Handhelds running on AA batteries often offer 20 to 250 hours of continuous use.

Choose a unit with long battery life to avoid frequent charging during extended trips or remote sailing destinations.

Water Resistance and Durability

Marine environments are harsh with salt spray and splashes. Look for devices with IPX6 or IPX7 ratings to ensure protection against water ingress.

A rugged floating design is an added safety feature to prevent loss if the device is dropped overboard.

Preloaded Maps and Features

Some units come with preloaded coastal charts while others offer only basemaps. Sailing-specific features like SAILASSIST provide racing tools such as virtual starting lines.

Check if the included maps match your sailing region and if you need specialized sailing tools for your activities.

Connectivity and Integration

Advanced chartplotters support network protocols like NMEA 2000 to connect with sensors, autopilots, and radar systems. This integration provides a unified dashboard for vessel monitoring.

Consider how well the device integrates with your existing marine ecosystem before investing in larger fixed displays.

How to Use and Care for Your GPS for Sailing

Start by entering your home port or a reference point as your first waypoint. This ensures you can always return to a safe location even if conditions change rapidly.

Regularly update your software and maps to benefit from new features and corrections. Use the companion app on your smartphone to manage these updates efficiently.

Keep the lens clean with a soft cloth to prevent scratches that could obscure your view. Store the unit in a dry place when not in use to preserve battery life and electronics.

Frequently Asked Questions

What is the difference between a handheld GPS and a chartplotter?

A handheld GPS is portable and runs on batteries making it ideal for day trips or as a backup. A chartplotter is a fixed unit mounted on a helm offering larger screens and integration with boat systems.

Handhelds typically last 20 to 250 hours depending on usage. Fixed units rely on boat power but may need backup batteries for safety during power outages.

Are these devices waterproof?

Most models are water-resistant with ratings like IPX6 or IPX7. However not all are designed for submersion so check the specific rating for protection levels.

Can I use these devices on other sports?

Yes most units include TopoActive maps for hiking and cycling. They work well for shore excursions when you dock at a destination.

Do I need a subscription for GPS service?

Standard GPS tracking does not require a subscription. However some connectivity features like real-time weather may require an app subscription or data connection.

How do I update maps on my device?

Connect your device to a computer or use the companion app on your smartphone to download and install updates. Keep your device charged during this process.

Final Thoughts on Choosing the Best GPS for Sailing

The Garmin GPSMAP 79sc stands out for its balance of chart coverage and rugged design. It suits sailors who want preloaded coastal maps without the complexity of a large chartplotter.

Consider your primary use case whether it is racing, cruising, or fishing when choosing features. Battery life and display size often dictate convenience more than advanced specs.

Prices and availability vary frequently so check current details before making a purchase. Ensure the selected model matches your specific navigation needs for a safe voyage.
