Buying Guide – How to Choose the Best GPS for Sailing

Selecting the right GPS for sailing involves understanding specific needs such as display size, durability, and specialized marine features that enhance safety.

Display Quality

A clear sunlight-readable display is vital for sailing where glare can obscure critical navigation data. Look for high-resolution screens that allow you to see maps and data easily even on bright sunny days.

Water Resistance

Marine devices must withstand exposure to water and salt spray to survive in harsh environments. Ensure the unit has at least an IPX6 or IPX7 rating to guarantee protection against splashes and rain.

Battery Life

Extended sailing trips require a device with long battery life to avoid frequent recharging. Handhelds often use AA batteries which can be easily replaced, making them a practical choice for emergencies.

Chart Support

Preloaded coastal charts save time and ensure you have detailed harbor data without extra purchases. Check if the device supports additional SD cards if you need more map data for international travels.

Satellite Support

Multi-GNSS support improves positioning accuracy by utilizing multiple satellite constellations like GPS and GLONASS. This ensures reliable tracking even in challenging locations where signal obstruction might occur.

Mounting Options

Fixed units should have secure mounting points while handhelds often come with lanyards for easy attachment. Consider how the device will stay on your vessel during movement or rough seas.

Specialized Features

Features like virtual starting lines or tack assist are valuable for competitive sailing or race performance. Assess whether you need these tools or if basic tracking is sufficient for your recreational needs.

Connectivity

Modern devices often offer Wi-Fi or Bluetooth for syncing maps and updates with your smartphone. This ensures your navigation data stays current without needing a physical computer connection.

How to Use and Care for Your GPS for Sailing

Always test your GPS device on land before heading out to ensure it is functioning correctly and you understand the interface. Familiarize yourself with basic functions like marking waypoints and checking battery levels to avoid surprises at sea.

Frequently Asked Questions

Do handheld GPS devices work effectively for sailing?

Yes, handheld GPS devices are highly effective for sailing because they are portable and often feature waterproof designs that survive marine environments. Models like the Garmin GPSMAP 79sc offer floating capabilities and preloaded coastal charts specifically for boat navigation.

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

A chartplotter is a fixed device installed on a vessel with larger screens and more complex marine navigation features. A handheld GPS is portable and easier to move around the boat, making it ideal for backup or small craft.

Can I use a handheld GPS in salt water?

Yes, but you should rinse it with fresh water after exposure to salt to prevent corrosion. Look for units with high IP ratings like IPX7 which indicate they can withstand splashes and immersion safely.

How long does a GPS battery last on a typical trip?

Battery life varies by model but many units offer 15 to 25 hours on standard batteries. Some like the eTrex SE provide up to 168 hours in standard mode which covers multiple days of continuous use.

Do I need special charts for sailing?

Sailing requires detailed coastal charts that show water depths and hazards which standard maps do not provide. Ensure your GPS supports marine charts like BlueChart g3 or Navionics+ for safe navigation.

What are the benefits of a floating GPS?

A floating GPS ensures that if the device falls overboard, it stays visible and retrievable. This feature protects your investment and maintains navigation capability during rough conditions or capsizes.

Can I connect a GPS to other marine instruments?

Many premium chartplotters like the GPSMAP 9210 support NMEA networks to connect with autopilots and depth sensors. Handhelds generally function independently but may sync data via smartphone apps.
