Komodo Liveaboard Cabin Types Compared

Most Komodo liveaboards sell three cabin grades: lower-deck, main-deck and an upper-deck master. A lower-deck midship cabin moves least and suits anyone prone to seasickness; an upper-deck master buys daylight, space and privacy. Pick position before grade. GumilangTour, a Lombok-based direct tour company, assigns cabins on enquiry and quotes per group.

Which Komodo liveaboard cabin should you book?

Book a lower-deck midship cabin if anyone in your party is prone to seasickness, a main-deck cabin if you will be diving or travelling with young children, and an upper-deck master only if you want space and privacy more than stillness. Position beats grade.

Every Komodo liveaboard brochure sells you a grade: Standard, Deluxe, Superior, Master. Almost none of them sell you a position — and position is what you will actually feel for three nights.

Two cabins on the same boat, both badged "Deluxe", can behave like different vessels. One sits midship, low, close to the keel, and barely moves. The other sits forward of the mast, two metres higher, and pitches on every swell out of the Sape Strait. Same price bracket. Same photograph, more or less. Completely different night's sleep.

So if you take one line from this page, take this: ask for the deck and the fore-aft position, not just the grade name. Most boats will accommodate the request if it comes in early, because cabin allocation is usually done by hand a few days before departure.

This page assumes you have already chosen a boat. If you have not, start with our guide to how to choose a Komodo liveaboard boat and come back here.

What the three decks actually are

Nearly every phinisi-style boat working Komodo National Park is laid out over three levels. The naming varies; the physics does not.

Lower deck

Below or roughly at the waterline. Cabins here are the least expensive on almost every boat, and they are also — counter-intuitively — the most comfortable in a seaway, because they sit closest to the hull's centre of motion.

What you trade is natural light. A lower-deck cabin has a porthole, a sealed window, or nothing at all. Some are genuinely windowless. Headroom is often reduced under the deck beams. On older hulls you may hear the engine and the shaft while the boat is under way, though on many builds the engine room sits aft and the forward lower cabins are quieter than the saloon above them.

Main deck

Level with the dining saloon and the dive platform. This is the middle grade on most boats and the most practical one for anyone who will be in and out of the water repeatedly, because you are not carrying wet kit up or down a ladder.

Main-deck cabins usually have a real opening window rather than a porthole. Motion is moderate. The cost is noise of a different kind: you are next to the saloon, the galley and the crew's working route, so you hear the boat waking up at 05:00 whether you wanted to or not.

Upper deck and the master cabin

The top grade. Usually one or two cabins, often with a king bed, the largest bathroom on the boat, and sometimes a private outdoor area. This is what you are paying for on a premium booking, and on a calm night it is genuinely the best room afloat.

The trade is motion. Every metre you sit above the centre of gravity multiplies the arc you swing through when the boat rolls. An upper-deck master in a 2-metre beam sea is a noticeably livelier place to sleep than a lower-deck cabin on the same hull.

Which cabin type suits which traveller?

The table below is the one GumilangTour works from when placing guests on a Komodo liveaboard. Read it by row, not by price: the left-hand column is a deck and a fore-aft position, because both change how the cabin behaves.

Read that table alongside the itinerary you have booked. A 3D2N liveaboard does one long overnight crossing; a 4D3N does two. If you are weighing those two lengths, our 3D2N vs 4D3N comparison covers why the fourth day is really about tide windows rather than distance.

Why does a midship cabin move less?

A midship cabin sits close to the point a hull pivots around, so it travels through a smaller arc than a cabin in the bow or on the upper deck of the same boat. That is why the least expensive cabin grade on a Komodo liveaboard is often the most comfortable one to sleep in.

Here is the part most travellers get backwards. The dry season is not automatically the flat season in this part of Indonesia.

BMKG, Indonesia's meteorological agency, publishes a rolling maritime forecast for the Flores Sea. Checked on 30 September 2026, it showed wave heights of 0.9 to 1.2 m, classified Rendah (low), with easterly winds of 9 to 12 knots gusting to 23. During the southeast monsoon months the same page routinely shows 1.25 to 2.5 m in the Flores Sea and the southern Sape Strait — which is exactly the June-to-August window when most people book.

That range is not dangerous for a well-found boat. It is, however, precisely the difference between sleeping through the night crossing and lying awake bracing against a bulkhead. And it lands on the busiest sailing weeks of the year.

The practical rule: a lower-deck midship cabin travels through a much smaller arc than a bow or upper-deck cabin on the same hull. If motion sickness is your main worry, the least expensive cabin on the boat is usually the right one — which is a rare and pleasant thing to be able to say. Check the forecast yourself the week you sail; BMKG's page is public and updates daily.

What 2026 changed, and why the cabin is now the scarce thing

Komodo National Park moved to a hard visitor cap. From 1 April 2026 the park ran a limit of 1,000 visitors per day, booked through SiORA, the Ministry's official online reservation platform — walk-up tickets are gone, and on charter and shared departures it is your boat operator who registers you, not you.

Then it tightened again. The 2026 annual allocation of 365,000 visitors was exhausted in August 2026. On 22 September 2026, Lugi Hartanto, acting head of the Komodo National Park Authority (BTNK), confirmed the park would run a reduced ceiling of 500 visitors per day for September to December 2026.

That halving matters to you as a cabin buyer in a way it does not to a day-tripper. Fewer park slots per day means boats consolidate departures rather than sail half-full. Consolidated departures fill from the top and the bottom of the cabin list first — the master goes to whoever books earliest, and the lower-deck berths go to solo travellers and couples watching cost. The cabins that vanish last are the middle ones, and the specific positions within a grade disappear long before the grade itself sells out.

Translated: in the current quota regime, "we have Deluxe availability" and "we have the midship Deluxe" are very different sentences. Ask the second question.

On fees, expect a park entry charge of IDR 250,000 per foreign visitor per day, with a diver surcharge and a harbour fee of around IDR 25,000 each per person per day on top (checked September 2026 — confirm the current figures on SiORA when your operator registers you). Our Komodo National Park entrance fee and permits guide breaks down how those charges stack across a multi-day trip.

Five things a cabin photograph never shows

Brochure shots are taken in port, in daylight, with the bed made and the door open. Here is what to ask about instead.

1. Where the air-conditioning compressor sits. A cabin can be beautifully finished and still be directly under or beside the compressor unit, which cycles all night. Ask which cabins share a bulkhead with it.
2. Porthole, window, or nothing. "Sea view" in a listing sometimes means a 20 cm porthole at shoulder height. If waking up to daylight matters to you, ask for the glazing dimension, not the adjective.
3. The bathroom pump. Most ensuite heads on these boats run on an electric macerator pump. It is loud, and it is loud in the cabins either side of it too. On a boat with four lower-deck cabins in a row, the one at the end of the run is the quiet one.
4. Door swing and standing room. Ask whether two adults can stand and dress at the same time. On many lower-deck cabins the answer is no, and that is a three-night problem rather than a one-night one.
5. Bed geometry. "Double" on a phinisi often means a mattress tucked against two bulkheads, so whoever sleeps inboard climbs over the other person to get out at 04:30 for the Padar sunrise hike. Twin beds are frequently the better marriage decision.

Worked example: nine people, four cabins

A real allocation problem, and the logic we use.

The group: two grandparents (68 and 71, one of whom gets carsick on winding roads), two couples in their thirties, and three children aged 6, 9 and 13. Nine people, a 3D2N itinerary. The boat has one master, two upper-deck, three main-deck and two lower-deck cabins.

The naive allocation puts the grandparents in the master — it is the nicest room, and it feels respectful. That is the wrong answer. The master is the highest and usually the most aft cabin on the boat, and the person who gets carsick on a road will have a hard night in it during the crossing to Komodo.

What we would actually do:

• Grandparents to the lower-deck midship cabin. Least motion, closest to the centre of the hull, and nothing to climb to reach the bed. Flag the mobility point to the crew so someone walks them up for the sunrise tender.
• Couple A to the master. They are in their thirties, they will enjoy the space, and they are the least likely to be troubled by roll.
• Couple B with the 6-year-old to a main-deck cabin. A main-deck cabin is next to the saloon, which is where a small child will want to be at 06:00 anyway, and it avoids carrying a sleepy six-year-old down a ladder in the dark.
• The 9- and 13-year-olds to the second main-deck cabin, twin beds, directly adjacent to Couple B. Adjacency is the point here; grade is not.
• Remaining upper-deck and lower-deck cabins left unbooked or released back.

Notice that the highest-grade cabin went to the people who needed it least, and the least expensive one went to the people it helped most. That is usually how a good allocation looks.

Safety: what to check before you sleep in it

Indonesian authorities tightened oversight of tourism vessels in Labuan Bajo after a run of incidents. KSOP Labuan Bajo — the harbourmaster's office — issued implementing guidance on 14 October 2024 covering speedboats, pinisi and other wooden-hulled passenger vessels. It requires, among other things, seaworthiness documentation and a master's sailing declaration, a weather check reported to the harbourmaster at least six hours before departure, a passenger manifest that matches who actually boards, life jackets and lifeboats sufficient for everyone aboard, and a safety demonstration before the boat sails.

Those are duties on the vessel. Here is your half of it, and it takes ninety seconds once you are shown to your cabin:

• Find the life jacket in your cabin and check the size. Children's jackets are a separate stock and are not always distributed automatically.
• Walk your exit route from the cabin to open deck in daylight, then once more after dark. From a lower-deck cabin this may be a single companionway ladder.
• Confirm the muster point with a crew member, in words, not by nodding at a diagram.
• Check that the cabin door latches open from the inside without a key.

None of this is alarmist. It is the same thing you would do in an unfamiliar hotel, compressed into a smaller space with fewer exits.

How to ask for the cabin you want

Send one message, at the time of enquiry rather than the week of departure, containing four things: how many of you there are and who shares with whom; whether anyone is prone to motion sickness; whether you would rather have light or stillness if you cannot have both; and any mobility constraint that makes a ladder a problem.

That is enough for a boat manager to place you sensibly. What does not work is asking on the pier, when the manifest has already gone to the harbourmaster and the cabin list is fixed.

If you are still deciding between a shared departure and taking the whole boat, a private phinisi charter removes the allocation problem entirely, because you assign the cabins yourself. And for everything that goes into the cabin, our Komodo liveaboard packing list explains why a soft bag is not a suggestion: there is nowhere on a boat to store a hard suitcase.
