Best Boating Apps: Navigation, Fishing, Weather & More

Reshared from

Although we always have to remember that cell phone coverage can be sketchy on the water and you should never depend completely on a phone for safety reasons (see our Boating Safety Guide to learn more about how to stay safe on the water), there are a slew of awesome boating apps out there that can make life better for boaters. And these days, just about everyone has a phone sitting at the helm and USB ports scattered throughout the boat.

So let’s take a look at a few popular selections from five categories of boating apps:

  • Marine Navigation Apps
  • Fishing Apps
  • Apps for Sailing
  • Weather Apps
  • General Boating Apps

Marine Navigation Apps

knowwake boating navigation app


Almost everyone has a go-to GPS and navigation app that they like to use in the car—whether that’s Google Maps or a crowdsourcing tool like Waze—and the same should be true for boaters. KnowWake delivers all that and more by creating a real-time community of boaters across North America, Canada, parts of the Caribbean, Australia and New Zealand, covering coastal waterways and more than 350 inland lakes and rivers.

KnowWake provides its users with an easy way to explore all the dockside and waterfront locations available by boat. Users will find everything from local restaurants, marinas, fuel docks, boat ramps, dive shops, inlets, dive sites, snorkel areas, and so much more.

Price: Yep, you’re in luck—this one’s free.

iNavXinavx navigation app

If you’re looking for an in-depth app that morphs your phone into a serious navigational tool, this might be your pick. You can bring up charts on-screen, navigate more or less as you would on a chartplotter, display instruments like speed and bearing, and even pull in NMEA data via WiFi. iNavX also has some interesting add-ons like tides and current data, GRIB weather forecasting, and an anchor alarm.

Price: The app goes for $4.99, and in-app purchases (like buying new charts) apply.

If you want to turn your phone or tablet into a chartplotter, Navionics is tough to beat. In fact, it’s the most popular boating app around and has world-wide chartography coverage for oceans, bays, and lakes. You can use it to navigate with some advanced features including dock-to-dock auto-routing; you can see user community updates; you can synch it with your onboard chartplotter if it’s WiFi-equipped, and more.

Price: The basic version comes free for two weeks; subscribing for a year costs $30.

Apps for Sailing

sea tow appSea Tow

Waterway Guide Marinas

This is a relatively simple, free app which lists out listings for over 3700 marinas and boatyards nation-wide.

We have to stress once again that boaters should never rely 100-percent on a cell phone for tasks like navigation and communications at sea. That said, however, each and every one of these apps can make your day of boating a better experience.
