Cruise Ship Watch · A 3Brains app

You book months in advance. Then something changes.

Cruise Ship Watch keeps an eye on your ship — itinerary shifts, advisories, incidents, port changes — and tells you when something does. So you can plan ahead instead of finding out at the gangway.

Watch your ship before you sail.

Cruise Ship Watch — Find My Ship

— 01

How it works.

i.

Find your ship.

Enter the ship name, cruise line, and region. Partial names accepted — we'll find it.

ii.

Add it to your watchlist.

Watch one ship for an upcoming trip, or several if you cruise often. Each ship gets watched independently.

iii.

We alert you.

Itinerary shifts, port advisories, ship incidents, mechanical or weather delays — if it affects your sailing, we'll tell you about it.

— 02

A quick tour.

Cruise Ship Watch pulls from public maritime sources, port advisories, and cruise line announcements — and surfaces the things that actually affect your sailing. No marketing emails. No upsells. Just changes worth knowing about.

```
Cruise Ship Watch — Your Watchlist
Your watchlist

Watch the cruises that matter to you.

Your upcoming trip. The cruise your parents are taking next month. The honeymoon you booked for next year. Each ship is watched independently, with its own region. Tap any ship for the latest.

Cruise Ship Watch — My Ships
My Ships

Saved ships, at a glance.

Once you've added a ship to your watchlist, it shows up in My Ships with its region and status. Tap any one for the latest news, or remove it any time.

Cruise Ship Watch — Travel advisory detail
Ship detail

The full picture, in plain language.

Tap a ship and see exactly what's going on — travel advisories at every port, the State Department's risk level, plus reasons (crime, civil unrest, health). The information you need to make a call, presented without jargon.

Cruise Ship Watch — Alerts
Alerts

Find out before the cruise line emails you.

Travel advisories. Port closures. High-seas forecasts. Cruise Ship Watch surfaces the changes that affect your sailing — often before the official notification reaches your inbox. So you can plan ahead, not catch up.

Put Cruise Ship Watch on your phone.

Or just try it now — open it in your browser:

Open Cruise Ship Watch

Cruise Ship Watch is a web app — it installs in one tap, with no app store needed. Once installed, it has its own icon on your home screen and runs full-screen, just like any other app.

iPhone & iPad Safari

  1. Open cruiseship.watch in Safari (not Chrome — Apple only allows installs from Safari).
  2. Tap the Share button — the square with an arrow pointing up — at the bottom of the screen.
  3. Scroll down in the share menu and tap Add to Home Screen.
  4. Tap Add in the top-right corner. That's it.

The Cruise Ship Watch icon will appear on your home screen next to your other apps. Tap it any time to launch.

Android Chrome

  1. Open cruiseship.watch in Chrome.
  2. Tap the three-dot menu in the top-right corner.
  3. Tap Install app — or Add to Home Screen, depending on your version of Chrome.
  4. Tap Install. That's it.

Some versions of Chrome show an automatic install banner at the bottom of the page — you can use that instead if you'd like.

Already on your phone? Just open it.

A few honest questions.

Which cruise lines are covered?
All major operators — Royal Caribbean, Carnival, Norwegian, Princess, Holland America, MSC, Celebrity, Disney and others. If your ship has a regular itinerary, we can watch it.
Where does the data come from?
Cruise Ship Watch pulls from public maritime sources, port advisories, and cruise line announcements. We surface the changes that actually affect your sailing — not marketing emails or upsells.
Will I find out before the cruise line tells me?
Often, yes — especially for port advisories and weather-driven changes that hit public sources before the cruise line's outbound notification cycle. We can't promise it every time, but that's the goal.
Does it cost anything?
No. Cruise Ship Watch is free. There are no ads and no subscriptions on the core experience.
Can I watch a sailing that's a year away?
Yes. Add the ship now and Cruise Ship Watch will keep an eye on it through your sailing date. Many of the most useful alerts happen weeks or months in advance — itinerary shifts, port closures, scheduling changes — so the earlier you start watching, the better.
Can I delete my watchlist or my account?
Yes — any time, from inside the app. We don't make it hard.
