Buying Guide – How to Choose the Best GPS for Sailing

Selecting the right GPS for sailing depends on your vessel size, budget, and specific navigation needs. Consider these factors to find a device that ensures safety and accuracy.

Display Quality and Size

The display is the primary interface for your navigation data so clarity and size are paramount. For handhelds, a sunlight-readable screen ensures you can see coordinates without squinting in bright conditions. Chartplotters benefit from larger high-resolution displays that allow for detailed chart views alongside system info.

Prioritize screens with high brightness settings and anti-glare coatings to maintain visibility on deck during the day.

Battery Life and Power Source

Battery life is critical for handheld units used during multi-day trips or emergencies. Look for models that offer at least 20 hours of use on standard AA batteries to reduce reliance on charging cables. Fixed units draw power from the boat, but backup battery options are useful for emergencies.

Choose devices with efficient power modes or replaceable batteries to ensure continuous operation when away from shore power.

Chart and Mapping Support

Some devices come with preloaded charts while others require purchasing separate cards for specific regions. Verify that the unit supports the marine charts you plan to use for your sailing routes. Compatibility with standard map formats allows you to update data easily over time.

Ensure the chosen GPS supports the map formats necessary for your sailing area to avoid costly or complicated updates later.

Durability and Water Resistance

Marine environments expose electronics to saltwater humidity and physical impacts so durability is non-negotiable. Look for IPX7 or IPX6 ratings that guarantee protection against splashes rain or accidental drops. Floating designs add a layer of safety for handheld units used near water's edge.

Select a device with a rugged build and waterproof rating to ensure it survives harsh weather conditions on the water.

Satellite System Compatibility

Modern GPS units often support multiple satellite constellations like GPS GLONASS and Galileo for better accuracy. This support helps maintain a signal in challenging environments where a single system might struggle to lock on. Check the specs to ensure the device covers the regions where you plan to sail.

Choose models with multi-constellation support to guarantee reliable tracking regardless of geographic location or atmospheric conditions.

Connectivity and Integration

Advanced sailors may need to connect their GPS to autopilots radars or other sensors via NMEA ports. Fixed chartplotters usually offer these ports while handhelds may rely on Bluetooth for app connectivity. Ensure the unit fits into your existing electronics ecosystem without requiring extra adapters.

Verify that the device supports the connectivity standards required for your marine network to enable seamless data sharing.

Specialized Sailing Features

Some models offer specific tools like virtual starting lines tack assist or sailing polars for racing. These features can significantly enhance performance and safety for competitive sailors. Standard units might lack these tools but can still serve well for general navigation needs.

Decide if specialized tools like tack assist are necessary for your sailing style before choosing a premium model.

Storage Capacity

The amount of internal memory determines how many waypoints routes and tracks you can store on the device. Expandable storage via SD cards offers flexibility for adding detailed maps without upgrading hardware. Adequate storage prevents data loss during long voyages where you may want to log many points.

Look for devices with ample internal memory and SD card slots to manage large amounts of navigation data effectively.

How to Use and Care for Your GPS for Sailing

Begin by inserting charged batteries or connecting the device to a power source. Follow the on-screen setup to select your preferred units and map style. Ensure you are in an open area to establish a strong satellite lock before heading out.

Keep the lens of the device clean and free from salt spray or debris that could obscure the display. For handhelds, use a lanyard or secure mount to prevent accidental drops overboard during rough weather. Regularly update the software to access the latest maps and feature improvements.

When the trip is finished, wipe the unit with fresh water to remove salt residue and dry it thoroughly. Store the device in a dry place away from direct sunlight to preserve battery health. Check battery levels before every use to ensure reliable performance on the water.

Frequently Asked Questions

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

A handheld GPS is portable and often floats making it easy to carry around the boat. A chartplotter is usually fixed to the helm and offers a larger screen with advanced connectivity for full boat systems.

Do I need to buy extra charts for these devices?

Some units come with preloaded basemaps or coastal charts while others may require buying separate memory cards. Always check the product description to confirm what is included before purchase.

How long does the battery last on a typical GPS unit?

Most handhelds offer between 20 to 168 hours of battery life depending on the mode and settings. Fixed units rely on your boat's power system so battery is rarely a concern for them.

Are these GPS devices waterproof?

Many models are rated IPX6 or IPX7 which means they can withstand rain and splashes effectively. However, full submersion protection should be checked as not all floating devices are rated for deep water.

Can I use these GPS units for land navigation too?

Yes most handheld models support both marine and land navigation maps for versatile use. Some units come with Topo maps which are useful for hiking near coastal areas.

What is SAILASSIST and does it help with sailing?

SAILASSIST is a feature set that includes tools like virtual starting lines and tack assist. It is designed to help racers and serious sailors optimize their performance and strategy on the water.
