A World of Warcraft addon.

Nauticus tracks the precise arrival & departure schedules of boats and Zeppelins around Azeroth and displays them on the Mini-Map and World Map in real-time.

Formerly called ZeppelinMaster, it has since been completely rewritten using the Ace3 framework and Esamynn's Astrolabe library.

The latest version can be downloaded from any of the popular WoW addon hosting sites -, or I recommend the latter:


Nauticus - A World of Warcraft addon

Nauticus tracks the precise arrival & departure schedules of boats and Zeppelins around Azeroth and displays them on the Mini-Map and World Map in real-time.

Look up arrival & departure schedules for any transport and know exactly when you need to be there. Less time waiting on platforms, more time at the AH or mailbox, less duelling rogues or shamies who want you to take a seat while they crit you... 'for fun'...

To track a transport requires that you, or someone else running the addon, has taken the route sometime earlier. Nauticus uses hidden addon-to-addon communications to synchronise and share up-to-date schedules between players automatically.

Important: This addon works best the more players on your realm also using the addon. So get your friends and guild mates to install Nauticus - the more the merrier! Even if you don't use transports because you're only ever in Outland, you can help store and transmit up-to-date data to everyone that needs it. Nauticus performs well in the background and you can disable the map icons for zero interference.

Main Features

† If you're new to Broker plugins, they're a bit like FuBar plugins but displayed how you want. Try StatBlockCore, Button Bin or Fortress for display addons. Titan has LDB support built-in. FuBar requires the lightweight bridge addon Broker2FuBar (not to be confused with FuBar2Broker, which does the opposite).


Find out the status of a transport via World Map/Mini-Map or via an LDB button display.

For options, type /nauticus or /naut in the command line.


* Auto pop-up tooltip and/or sound arrival/departure alarm (i.e. Zeppelin horn or boats bell) when at platform

Nauticus is always in continual development. You should try to keep your version up-to-date, not least because the addon interacts with other users and they rely on good quality data from you. You'll be notified upon login when there's a new version available, after other users are seen using a later version. For this reason, please DON'T redistribute or include in a compilation pack!

Frequently Asked Questions

Q. I just installed Nauticus, why don't I see any schedules?
A player with the addon needs to travel on the boat/Zeppelin/turtle before the schedules come up. This could be you or someone else who may have taken the transport earlier. The most recent schedules are synchronised between other players running the addon, so after a short while the data will most likely be available to you before you take any transport. Get as many of your friends and guild mates to install Nauticus - the more the merrier.

Q. How does Nauticus get the schedules?
There are no Blizzard-provided API methods to directly determine the transport schedule. Thus we do it indirectly by getting player coords and comparing them to a known set of coords along the route. When the player 'triggers' these coords, we know the cycle and can subsequently work out future schedules at any point in time.

Q. How accurate is it?
Round-trip cycles have been calculated to one microsecond (six decimal places) over a 1-2 week period. This is significantly better resolution than provided by the API, which only measures in milliseconds (three decimal places). Baring slight adjustments in Blizzard's clocks etc., 99.9% of the time there should be no observable drift of more than a second or two.

Q. Why are some of my schedules wrong?
Rarely, schedules can become corrupted due to changes in your computer's system clock that may occur between WoW sessions/reboots. This can also be caused by dodgy CMOS batteries and some over-clocked systems. Otherwise, Nauticus can normally keep track of schedules between reboots. Additionally, while realm servers appear to keep very precise clocks for running the transports and to generate their positions, from time to time they may re-synchronise these clocks, sending the data slightly out of wack. Nauticus should quickly fix the schedules, as it will gather more recent and better quality data from other
users or from your own travels.

Q. Doesn't weekly maintenance ruin the schedules?
It doesn't! We can only assume how Blizzard calculates transport schedules and their positions but it's probably based on the realm server's system clock, which is likely synchronised with a centralised ntp time server at each data centre. You can verify this by visiting another realm (at least, in the same geographical location - e.g. EU, US Eastern) to observe exactly the same schedules. This is another way to obtain accurate schedule data - from other realms. If there is one, an epoch is presently unknown - if any maths wiz can manage to reverse engineer it (simultaneous equations?), do let me know!

Q. Why does Nauticus have to use a chat channel?
Blizzard's SendAddonMessage() API is effectively limited to guild and raid addon communication, which is insufficient to get data spread furtherest across your realm. For maximum availability and accuracy of schedules, we need to use a chat channel. You shouldn't be concerned if you have the channel slot spare - we're extra careful not to mess up channel numbers.

Q. Where did the GUI disappear to?
The red window was removed in favour of map icons with tooltips. It became difficulty to maintain the rather clunky code necessary to provide this functionality and consumed more resources than desirable. Plus it didn't cater for other languages very well due to its fixed size. Native FuBar support was removed in favour of LibDataBroker (Broker/LDB) displays. Broker allows you to choose your method of displaying plugins. The lightweight bridge addon Broker2FuBar returns the old FuBar functionality, as well as allowing you to put it as a Mini-Map button (even if you don't use FuBar).

Q. Can you add the Deeprun Tram?
Unfortunately no, since it's treated as an instance and we can't properly track player coords within instances.
