Short answer. A wooden phinisi is quieter, warmer to be on and rolls more slowly; steel is stiffer, easier to fit out as a dedicated dive platform and cheaper to maintain per year. In Komodo the practical differences show up in night-time noise, cabin heat, deck space and how often the boat leaves service — not in safety.
Almost every liveaboard in Labuan Bajo is one of two things: a hand-built timber phinisi from the South Sulawesi tradition, or a steel or fibreglass vessel built to a drawing. They sell the same itinerary and deliver noticeably different weeks.
The honest comparison
| Wooden phinisi | Steel or GRP liveaboard | |
|---|---|---|
| Construction | Hand-built in Bulukumba, South Sulawesi — ironwood (ulin) keel, bitti and teak planking, wooden dowels, natural-fibre caulking. UNESCO-listed craft since 2017 | Welded or moulded to naval-architecture drawings, usually overseas or in a commercial yard |
| Motion | Heavy displacement; slow, deep roll. Less jarring, more pronounced | Stiffer, quicker roll; can feel snappier in short chop |
| Noise | Timber absorbs. Quieter under way; hull slap is softer | Steel transmits. Engine and generator noise carries further through the structure |
| Heat | Timber insulates reasonably well; upper decks stay usable | Steel absorbs and radiates heat; more dependent on air conditioning |
| Deck space | Generous open teak decks — the reason people book them | Often optimised for dive operations rather than lounging |
| Dive platform | Varies by boat; usually a tender-based operation | Frequently purpose-built: rinse tanks, camera table, dedicated ladder |
| Maintenance | Slipway roughly annually for hull cleaning, antifouling roughly every three years, periodic replanking | Longer intervals between yard periods; corrosion management rather than timber replacement |
| Lifespan | Decades with continuous maintenance; components are replaced rather than the whole hull | Long, with hull thickness surveys and coating cycles |

Does wood mean less safe?
No, and it is the wrong axis. What matters is the individual vessel: when it was last slipped, what condition the planking and fastenings are in, whether the bilge pumps and fire equipment work, and whether the crew drills. A well-maintained timber hull is a serious sea boat; a neglected steel one is not. Ask any operator for the specific certification carried by the specific boat you are booking and for the date of its last dry dock — that is the question with an answer, and the reasoning behind it is on the refit cycle page.
What does timber actually give you at night?
Two things you notice at 02:00. Wood does not ring. When the anchor chain runs out on a steel hull, the sound travels through the whole boat; on timber it is muffled two cabins away. And a wooden hull at anchor in a sheltered bay moves slowly enough that you sleep through it — the roll period is long, which is the same physics that makes a phinisi comfortable and makes it feel “rolly” to someone expecting a stiff boat.
That is the single most common misunderstanding about phinisi motion. More roll, gentler roll. The practical management of it is in the seasickness guide.
Which should a diver pick?
If you are doing three or four dives a day for a week, a purpose-built dive platform with rinse tanks, a camera bench and a wide ladder earns its keep. If you are doing one or two dives a day inside a broader cruise — which is what most Komodo guests actually do — the phinisi wins on everything that happens between dives: deck, shade, food and space.
| Traveller | Better fit | Why |
|---|---|---|
| Snorkellers and general cruisers | Wooden phinisi | Deck space, shade, quiet, and the boat is part of the experience |
| Two dives a day plus sightseeing | Wooden phinisi | Tender-based diving is entirely adequate at this volume |
| Four dives a day, camera rig, one week | Purpose-built dive vessel | Rinse tanks, camera bench, fast turnarounds |
| Families with young children | Wooden phinisi | Open decks, slow motion, shaded lounging areas |
| Anyone photographing the boat itself | Wooden phinisi | There is no photogenic equivalent to a rigged phinisi at anchor |
Fit guidance from how these vessels are actually used in Labuan Bajo. Individual boats vary more than the categories do.
The part that is not on the spec sheet
A phinisi is the last working expression of a boatbuilding tradition that UNESCO inscribed in 2017, still built by hand in Tana Beru, Bira and Ara from ironwood keel up, with pegs instead of bolts through much of the structure. You are sleeping inside an object that was shaped rather than assembled. That is not a performance metric and it is, for most people who choose one, the actual reason — the craft itself is documented on the how a phinisi is built page.
What to ask about a specific hull
The wood-versus-steel debate is a category argument, and category arguments do not put you on a good boat. These six questions do, and they apply equally to both materials.
- When was the last dry dock, and what was done? “Last May, hull cleaned and antifouled” is an answer. “Recently” is not. Labuan Bajo’s slipway window clusters around May to July.
- What certification does this vessel carry? Ask about the specific boat rather than the fleet. An operator who can produce the paperwork for the hull you are booking is telling you something about how they run.
- How many crew, and what are their roles? Captain, engineer, cook, deckhands, guide — the ratio to guests tells you more about your week than the cabin photographs.
- What is the safety equipment and when was it last serviced? Life jackets sized for children, liferafts, fire extinguishers, a working radio and a plan for a medical evacuation from an anchorage with no signal.
- How is the generator run overnight? This single answer decides whether you sleep well. Some boats run through the night for air conditioning; some shut down and open the ports.
- What is the fresh water capacity and is there a watermaker? Showers on day three feel very different on a boat that makes its own water.
An operator who answers all six plainly is worth more than any hull material. The maintenance side of that argument is set out on the refit cycle page, and the craft itself on the how a phinisi is built page.
