What's New in TZ iBoat

4.1.2

September 17, 2026

• Keep Your Course in Sight You can now set your boat’s COG/SOG Predictor to Infinite, keeping your course visible all the way to the edge of the screen, whatever the chart zoom level. This lets you keep a long predictor for your own boat while using shorter predictors for AIS targets. Enable it from Settings.

2nd season

After 15 years of using Navionics I have switched to TZ and had a few issues at first. There are so many options and settings it is easy to get lost. But I am on my second season and I am very happy now. For me it is important that I keep the charts and functionality even once the 12 month are over. Unlike with the previously mention company. This seems to be the case with TZ if you download the charts onto your device, but I did get the subscription for another year anyway.
I use it on my iPad and iPhone. The anchor watch is a good feature…. It would be cool to get the anchor alarm onto the Apple Watch. I also like the weather features very much! I just hope you are not going to over improve every year!

Reste sur ma faim

Que dire de cette version? Elle a le mérite d’exister dommage que nous devions encore payer si comme moi on a la version PC Un avantage sur IPad Pro facile à caler pour contrôler le remps de quitter ou rentrer au port pour anticiper les bouées et les bancs de sable cartes Raster trop vielles choisir la version raster qui ceci dit en passant Acheter pour PC en vecteur la zone Caraïbes 3 jours plus tard on me propose une mise à jour pour 152€.......... mais j.aime la version pc avec routage Pour les enfants c’est très ludique Bonne continuation c’est ma troisième version
