Which GPS watch for sailing, foiling and paddling?

A watch for the water has a harder job than a running watch. It has to hold a reliable GPS signal through fast accelerations and constant changes of direction, stay usable with wet hands and gloves, remain readable in glare, and last through long days away from shore.

What makes a watch good on the water?

• GPS accuracy and recording rate. Everything else depends on it: speeds, distances, routes, personal bests and manoeuvre analysis. Newer models with multi-band GNSS and better antennas give cleaner tracks; the model generation matters as much as the brand.
• Battery in full GPS mode. Plan for your longest likely day, not your average afternoon. Always-on screens, cellular, music and multi-band positioning all add to the drain.
• Controls and display. Physical buttons work better than a touchscreen in spray or with gloves. A bright display helps in sun.
• Durability. Water resistance is the starting point. Salt, sunscreen, impacts and UV are part of the job.
• Racing tools. For racers, a clear countdown with sound or vibration alerts reduces the load in the final minutes before the start.
• Compatibility. Check that the watch works with your phone and that your watersports app supports it natively.

Native app or phone mirroring?

With a native watch app, the watch starts and stops the session, records GPS and shows key metrics while your phone stays dry on shore. A phone app that only mirrors notifications to your wrist depends on the phone being with you. For active sailing and riding, native support is the stronger option.

Which watch for which rider?

These are examples of models riders commonly use, grouped by what they are good at. Check the current generation before you buy.

• iPhone users who want one watch for everything: Apple Watch Ultra (current generation). Bright screen, Action Button to start quickly, optional cellular for when the phone stays on shore. A standard Apple Watch is enough for shorter sessions close to shore.
• Serious multisport and long days: Garmin fēnix (8, or the fēnix 9 launched in August 2026) or the marine-focused quatix 8. Strong GPS, physical controls, long battery.
• Sport first, light on the wrist: Garmin Forerunner 965. Bright AMOLED display, good battery, comfortable under a wetsuit cuff.
• Rough use and travel: Garmin Instinct 2X Solar. Durable, button-based, readable, built around battery life.
• Battery and value: COROS Apex 2 Pro or VERTIX 2S, a good fit for expedition paddlers and long training blocks.
• Outdoor and battery-minded athletes: Suunto Race or Suunto Vertical, with solid battery and mapping for remote sessions.

Is a Suunto (or any general sports watch) worth it for sailing? Yes, if you understand what you are buying. These watches record the basics very well: route, distance, time, speed and heart rate. What their native apps usually lack is sailing-specific analysis: speeds over set distances, tack and gybe breakdowns, comparisons by spot or conditions. That gap is filled by the app you sync to, not by replacing the watch.

Waterspeed works with Apple Watch, Garmin, COROS, Suunto and Wear OS. Garmin, COROS and Suunto sessions sync automatically once the watch is connected in Settings.

For sailors and racers

• Dinghy and foil racing without instruments: Apple Watch Ultra or Garmin fēnix. Both have dual-frequency GPS and buttons you can use with wet hands. Garmin has a regatta timer and tack assist built in; on Apple Watch, Waterspeed’s Race Countdown (Pro) starts from the Action Button.
• Garmin electronics on board: the quatix shows boat speed, depth, heading and wind from compatible Garmin marine electronics.
• Keelboats: a phone or tablet in the cockpit works as speed display, countdown and logger, so a watch is optional.

How to choose

Start with the sessions you actually do, not the ones you imagine doing next summer.

• 60–90 minute sessions near home: an Apple Watch or a mid-range sports watch is more than enough, and easier to wear every day.
• Racing, several sports, full days offshore: Garmin’s controls, marine options and battery depth matter more.
• Long expeditions with no charger: pick battery over screen quality.

Set up your watch before launch day

1. Update the watch and the app at home, and check permissions.
2. Pick the right activity profile. A windsurf session recorded as an open-water swim still gives a map, but the analysis won’t match how you move.
3. Build your data screen with only what you need. Elapsed time, current speed, max speed, distance and heart rate are a good start.
4. Practise the controls: start, pause, lock, countdown, without looking down for long.
5. Test GPS acquisition at the dock and wait for a solid lock before launching.
6. Wear it outside the wetsuit cuff, secured so it doesn’t rotate.
7. Stop promptly when you finish, so the walk back and the car park don’t inflate your distance and duration. If you forget, Waterspeed’s AutoTrim (Pro) removes the land sections.

The watch is half the system

Most wearable apps can tell you where you went. Fewer can tell you how well you rode or paddled. After each session, sync soon, check for obvious GPS errors, note one thing that went well and one target for next time. Over a season, that review is worth more than any single top-speed number.
