Buying Guide – How to Choose the Best GPS for Sailing

Choosing the right GPS requires evaluating how well it matches your sailing style, vessel size, and budget constraints.

Device Type and Portability

Decide whether you need a handheld unit for portability or a fixed chartplotter for a helm station. Handhelds are ideal for small boats, kayaks, or backup needs. Chartplotters offer larger screens and better integration with vessel systems.

Focus on choosing a type that fits your vessel layout and how often you move between boats.

Charting and Mapping Capabilities

Check if the device comes with preloaded marine charts like BlueChart g3 or if you must buy them separately. Preloaded charts save time and money but may limit regional coverage. Expandable storage via SD cards offers flexibility for adding custom maps.

Prioritize units with included coastal charts if you frequently navigate unfamiliar waters.

Water Resistance and Durability

Marine environments demand high durability. Look for units rated at least IPX6 or IPX7 for splash or submersion resistance. Floating designs are essential for handhelds to prevent loss overboard. Rugged casings protect against bumps and drops.

Ensure the device meets marine exposure standards to survive wet conditions.

Battery Life and Power Source

For extended trips, battery life is critical. Handhelds using AA batteries are easy to replace. Units with 20+ hours of operation reduce downtime. Check if the device supports external power ports for continuous use while docked.

Choose based on how long you can go between recharging or battery swaps.

Satellite Reception and Accuracy

Multi-GNSS support including GPS, GLONASS, and Galileo improves accuracy in challenging environments. Ensure the unit has fast signal acquisition and reliable tracking. Multi-band technology helps when navigating near dense trees or tall structures.

Select devices with expanded satellite support for consistent positioning.

Sailing-Specific Features

Advanced units offer SailAssist tools like virtual starting lines, tack assist, and MOB alarms. These features provide real-time sailing metrics and safety alerts. Check for compass accuracy and heading tracking even when stationary.

Prioritize models with racing or safety features if you participate in regattas.

Connectivity and Network Integration

Modern chartplotters integrate with autopilots, sensors, and engine monitoring via NMEA networks. Wireless connectivity allows app control and updates. Ensure the device supports necessary protocols like NMEA 2000 or OneHelm.

Look for connectivity that matches your existing marine electronics ecosystem.

Display Quality and Visibility

A clear, sunlight-readable display is essential for outdoor visibility. Larger screens help view multiple data points simultaneously. High-resolution color displays improve map readability. Check for anti-glare coatings and fogproof glass.

Select a screen size that balances visibility with physical space on your boat.

How to Use and Care for Your GPS for Sailing

Always update your device firmware and maps before a trip to ensure the latest navigational data and bug fixes are applied. Connect your handheld or chartplotter to a computer via USB or use Wi-Fi connectivity if supported for seamless downloads.

Calibrate the electronic compass regularly by moving the device in a figure-eight motion to maintain heading accuracy. This ensures reliable directional data especially when standing still or in areas with magnetic interference.

Protect your device from direct sunlight when not in use and store it in a dry place to prevent battery degradation. Clean the screen with a soft cloth and mild soap to remove salt residue and maintain display clarity.
