TZ MAPS: So much more than nautical charts

TZ MAPS introduces all of the following:

Features that keep you safe

Dynamic Mooring and Anchor Watch

Sailing can be unpredictable, so it is our priority to help keep you safe. Dynamic Moorings will help guide you to the safest location to anchor, based on important information such as real-time weather data and topography, while the Anchor Alarm feature will keep you informed and in control, triggering an alarm on your device should your boat stray too far from the anchored point.

Track, Analyze, Share & Connect

Trip Book to track, analyse, share and connect

Transform your phone into the ultimate marine logbook, by using the trips feature to log essential details such as distance, duration, COG, SOG, pictures, and catches. Start TZ iBoat before your trip, track your performances, revisit your data anytime, and locate the same great spot again by following the geo-reference of your photo.

Additionally, you can share your trips, and connect with friends and family in the app. You can also share your real-time location with your followers and loved ones, for added security.

Access unlimited weather forecasts

Premium Weather Service

In addition to multi-day weather forecasts, a premium weather service is also available on TZ iBoat that gives you access to unlimited, and precise weather forecasts to help you prepare for everything that lies ahead.

These forecasts include advanced weather displays and a meteogram, and are completely downloadable.

Fisherman Friendly!

Trip Book to track, analyse, share and connect

With the recent addition of BathyVision, the benefits to fishing enthusiasts have been elevated to a whole new level. This feature allows you to explore the ocean's depths, uncovering the perfect fishing spots. But that’s not all! TZ iBoat allows users to record essential data of their catch, such as weight, size, photos and exact locations. This feature will help you revisit your favorite fishing areas, to repeat your successes. Give it a try and make your trips more productive and enjoyable!
