Discover TZ iBoat, the latest innovative app powered by the world leaders in marine navigation solutions for over 30 years, MaxSea and Nobeltec.

Experience coastal navigation that uses the same technology as the most advanced sailors do with TIMEZERO, directly from your iPad.

This powerful app allows you to access worldwide chart coverage including the latest vector chart data, connect your GPS, AIS and even radar to your iPad for a complete navigation experience.

What is great about this app is that it contains the same fast and smooth chart engine that runs on the premium TIMEZERO advanced solution while trimming it down to the essential navigation tools.

While creating routes is as easy as ever, we have added satellite photo integration. The satellite photos combine with the charts to create the best of both worlds, letting you plan routes with precision and in 3D.

We recognize that some sailors prefer using raster charts, while others prefer using vector charts. That is why we have made both chart types available inside this powerful app. Select charts for any location around the world!

This app is ideal for anyone that is looking for a software to display charts and navigate in real-time with weather conditions and navigation data.

Features include:

• Plot your position in real-time on the best marine charts
• Photofusion with HR satellite photos (worldwide coverage)
• Route Planning
• Track recording
• Course (COG) & speed (SOG)
• Real-time local weather and weather trends
• Navigation in 2D or 3D Perspective
• Tides and Currents database
• AIS integration (optional module)
• Radar overlay with the new Furuno DRS4W (optional module)
• Sensor compatibility to display additional real-time information (depth, SOG etc.)

Here’s what our customers say about TZ-iBoat:

“Best Navigation App Interface” by Whitall

“Like probably most sailors and boaters, I've tried a number of navigation apps. Navionics, iNavx, Plan2Nav, even Garmin. I find this one far more intuitive, and beyond easy to use - a joy to use.”

Ease of use

TZ iBoat is one of the easiest and most complete aids to navigation on the market. The seamless charting works flawlessly, the detailed tides and currents right on the chart make it easy for anyone looking on. There is no time needed for flipping between programs which enables you to keep your eyes out on the water and not always buried in the screen. The distance and bearing feature is so easy ito use that identifying navigation aids and points of land with a hand bearing compass is fast and accurate. iBoat is clearly a fantastic navigation aid that when used with other aids such as hand bearing compasses, depth sounders, binoculars, etc, will help to make your trip as safe as possible. This aid to navigation does so much more including being able to add and remove features from your screen easily in order to keep your screen uncluttered works extremely well. I would rate this Nobeltec product higher than anything else seen on the market today. Look it up and I challenge you to find a more complete easy to use program.

Has surpassed the competition in most areas

I started using TZ about a year and a half ago. Before then I was a navx fan. TZ is so much easier to use and responds so much faster. The ease of creating and following routes is the best. Useful additions would be in the area of route and waypoint management. Another issue is when AIS targets are near the route line, the user must zoom to the max to separate the target from the route information window which comes up when the cursor is over it. Other than those small items, this is a great navigation app.

An upgrade done right

This is now nearly a full chart plotter. In addition to the previous features, including ability to display AIS and data such as depth, SOG, etc., it now displays wind data (Apparent, True, etc).

In addition, the transition from the old app MaxSea TZ TimeZero was done correctly for us pre-existing customers who had “purchased” maps. Those carried over! Excellent show of respect towards customers and very confidence-inspiring with regard to future "subscriptions".

TimeZero for iPad remains the gold standard in raster (paper chart-like) charting, with only official charts from the best official government hydro-graphic institutions (UKHO, Canada CHS, U.S. NOAA, France SHOM, Italy IIMI, Spain IHM, etc., etc.)

The branding is weak and a very poor marketing choice (“iBoat”), because it makes it sound as if this is some sort of toy. It is not. This is a very serious navigation program we use every day out in the water.

Thanks a lot for your nice input Xavier ! We will start our marketing campaigns shortly.
