Want to understand how the best GPS watch can help at sea? Here at Yachting World, we'll walk you through important features for determining your location.

Terminology like GPS is common in most sailor’s vocabulary. But when was the last time you thought about the magnitude of this technology at sea? Well, it’s even more incredible that the software that determines your location on Earth by receiving signals can be worn on your wrist. Although not a new bit of kit, the best GPS watch for navigating open water is essential for any shipmate.

How can you use a GPS watch at sea?

At the moment, GPS watch technology hasn’t overridden the need to invest in the best satellite messenger and tracker for heading off the beaten path or a marine GPS tracking device to help you accurately locate your yacht, catamaran or even a jet ski in real-time. So this begs the question, how can you use a GPS watch at sea?

For a start, each GPS watch has a small number of auto-tracking sports and a larger number of elective-tracked sports. Most often these types of watches are used for sports and fitness purposes, meaning that you can track a walk, run or jog. You can even turn this function on when you’re cleaning the deck to see how many steps you get in! If you go for a dedicated GPS watch like the Quatix 7, then you’ll get mapping on screen and tracking ability for a MOB situation.

Garmin Quatix 7

Best marine specific smart watch

• Facia sizes: Size: 47mm / 51mm
• Display: 1.4-inch sunlight-readable color AMOLED display with touchscreen and sapphire glass
• Battery Life: Up to 16 days in smartwatch powersave mode and up to 36 hours in GPS mode.
• Health and Fitness Tracking: Advanced health monitoring, heart rate monitoring, Pulse Ox, sleep tracking, and body battery.
• Navigation: Marine features including GPS, GLONASS, and Galileo support, barometer, altimeter, and compass.
• Sports Modes: Preloaded with various sports profiles including rowing, paddleboarding, and swimming.
• Smartphone Integration: Smart notifications, Garmin Pay for contactless payments, and compatibility with both Android and iOS devices.
• Marine Features: Boat data, sail racing assistance, anchor alarm, fishing calendar, tides, and more.
• Water Resistance: Up to 100 meters.

Reasons to buy: It has a large easy-to-read face, incredible versatility for an array of lifestyle activity, health, wellbeing and boat interactivity as well as being customisable to suit individual needs. Includes a dedicated MOB button.

Reasons to avoid: The battery life isn’t as good as the Quatix 6, it has bright facia which can be distracting, and the touchscreen is pointless without the additional kit it interfaces with.

Debating on upgrading to the Garmin Quatix 7? The next-gen sailing smartwatch includes improvements to strengthen integration with onboard electronics. For instance, the touchscreen model on this watch can be used to control MFD displays, Fusion audio systems and Garmin autopilots.

But if you’re a Quatix 6 user, here are the major changes for the Quatix 7 over the Quatix 6. The main difference is the display it’s bigger and brighter and touchscreen.

If you found darkness or difficulty seeing the Quatix 6 screen, this has been addressed with a much brighter lit-up option. Whilst this might appease a large number of wearers, it can be harsh for some especially if you’re a frequent night sailor like me.  The obvious compromise to this is that the battery life takes a hit if you want an always on display. To eek out the battery life, then you’ll need to switch the display to on demand motion controlled.

The Quatix 7 has integrated more functionality into the Garmin app on the phone, so it’s easier to make changes to the user functionality of various apps within the watch, rather than having to fiddle about doing them on screen as with the earlier Quatix watches.

The Quatix 7 is undoubtedly one of the best watches for sailors and boaters currently on the market. I love mine and feel undressed without it.

Garmin Vivoactive 4

Best GPS watch for sailors

Specifications: 5ATM waterproofing | contactless payment function | battery life up to eight days

Reasons to buy: Along with an excellent health focus and a smart design for daily wear, it also features an optical pulse monitor that works underwater.

Reasons to avoid: It’s likely that you will need to charge it two or three times per week which is not ideal for long voyages. As a larger-sized watch, it may also be bulky which will catch on equipment.

The model also offers emergency assistance, so once you have added an emergency contact to the device, you can hold down the buttons and it will trigger a call for you.

Some of the marine activities this GPS watch can support and detect are stand-up paddleboarding, rowing and pool swimming. An added extra is that workout moves can be shown on the screen to remind you to do your daily exercises and stretch, even while you are out at sea.

Fitbit Charge 5

Best GPS watch for tracking health

Specifications: Water-resistant up to 50m | contactless payment function | battery life of up to seven days

Reasons to buy: It has a slim device that fits easily under clothes, a smart wake alarm, and reliable auto-tracking.

Practical features such as ECG and EDA (electrodermal) scanning which is a method of monitoring latent stress, water-resistant up to 50m and activity tracking, make this ideal for your next adventure.

You can leave your phone at home or on the boat and you can view your GPS data on the map.

Recommended GPS watch

Specifications: 5ATM waterproofing | contactless payment function | battery life of up to four to five days

Reasons to buy: Looks stylish, has tactile and physical buttons, is practical in the water, and has almost every bell and whistle you could possibly want if you own a Samsung phone.

You can navigate the Samsung Watch 4 Classic’s GPS fitness tracker by rotating the bezel to scroll through and there are an additional two physical buttons too. These are useful if you intend to go in the water.

Touch screens aren’t too clever when they’re wet, so the presence of physical buttons indicates watery intentions for this device. It supports a wide array of sporting activities which includes kayaking, indoor rowing and swimming.

Samsung have created several variants of this watch but all are able to work with a wide array of apps, including Strava and other fitness or productivity apps.
