A phinisi is a heavy wooden hull with a deep, slow roll rather than the sharp snap of a light modern boat — which most people find easier, not harder. Discomfort comes from open crossings, not from anchorages, and almost every itinerary spends most of its hours at anchor in sheltered water. If you are prone to motion sickness: take medication before you sail rather than after, sleep low and amidships, eat something plain, and stay on deck where you can see the horizon. Almost nobody has a bad week; a few people have one bad crossing.
How does a phinisi actually move?
Displacement, weight and a low centre of gravity give these hulls a long-period roll. Instead of the quick jerk of a light planing boat, you get a slow lean one way and a slow lean back. Most people acclimatise to it within a day, and many who struggle on speedboats are perfectly comfortable on a phinisi.
What produces discomfort is not roll but combined motion — pitch and roll together, in a beam sea, at night, below decks, without a horizon. That combination occurs on open crossings, and only on open crossings.
Which passages actually move?
| Passage | Expected motion | Notes |
|---|---|---|
| Labuan Bajo day hops inside Komodo National Park | Minimal | Short legs between sheltered islands |
| Komodo north, dry season | Low | Protected water, short crossings |
| Komodo south, December–March | Moderate to high | Wet-season swell; the price of the manta season |
| Sorong to Dampier Strait | Low to moderate | Usually an overnight run in reasonable water |
| Dampier to Misool | Moderate | Genuine open water; scheduled overnight for a reason |
| Bali to Komodo crossing | Moderate | Open legs between Lombok, Sumbawa and Flores |
| Banda Sea crossing | Moderate to high | The most exposed routine route in Indonesia — hence only two seasonal windows |
Notice the pattern: the roughest routes are exactly the ones with fixed seasonal windows. The Banda Sea runs only in March–April and September–October precisely because operators will not cross it in the core monsoons. The full picture is in our monsoon map.
What actually works against seasickness?
| Measure | Timing | Effectiveness |
|---|---|---|
| Oral medication (per your pharmacist or doctor) | Before departure, then on schedule | High — if taken before symptoms, not after |
| Scopolamine patch | Applied hours before sailing | High; check side effects with your doctor |
| Horizon fixation on deck, amidships | Immediately | High and free |
| Fresh air | Immediately | High |
| Plain food — dry toast, rice, crackers | Before and during | Moderate; an empty stomach is worse than a light one |
| Ginger, in any form | Ongoing | Moderate, and harmless |
| Acupressure bands | Before departure | Variable; some people swear by them |
| Reading or screens below deck | — | Actively harmful. This is the mistake people make |
| Alcohol the night before a crossing | — | Makes everything worse |
Medication is a personal medical decision. Discuss it with a pharmacist or doctor before you travel, particularly if you are diving, since some antihistamine-based remedies cause drowsiness. Bring what you need from home — there is no pharmacy at anchor, and Labuan Bajo and Sorong carry only basics.
Where should you sleep?
Lower deck, amidships. That is the point of least motion on the boat, and it is worth trading a window for. Avoid the bow on any itinerary with open crossings — forward cabins pitch and can slam in a head sea. Upper-deck cabins have the best air and the best views and the most movement; they are the right choice for good sailors and the wrong one for the sensitive.
Full trade-offs by cabin position, including noise and heat, are in our guide to phinisi deck plans.
What can the crew change for you?
More than most guests realise. Tell them early — before you feel bad, not after.
- Route and timing. A captain can often delay a crossing by a few hours to take it in better conditions, or reroute behind an island.
- Speed and heading. A small change in angle to the swell transforms the motion. Captains do this routinely when asked.
- Anchorage choice. A more sheltered bay for the night is usually available.
- Crossing at night. People who are asleep feel far less. Overnight repositioning is standard practice partly for this reason.
- A place to lie down on deck. Crews will make up a mattress amidships on the main deck for anyone struggling. It is the single most effective intervention on the boat.
None of this is an imposition. Crews deal with it every week and would far rather adjust than watch a guest suffer in silence — and knowing who to tell is easier once you know the roles, which we set out in our guide to phinisi crew.
When should you say no to a crossing?
Rarely, but it is a real question. If you know you are severely affected, three sensible choices exist:
- Pick a sheltered itinerary. A Komodo national park charter in the dry season has almost no exposed water. The 4D3N itinerary is the gentlest multi-night option we run.
- Avoid the Banda Sea and long open crossings. These are the routes that break people. Save them for later, or never.
- Fly instead of sailing the delivery leg. On a Bali to Komodo crossing, the open water is the product — if that worries you, take a Komodo-only charter and fly to Labuan Bajo.
What you should not do is book a Banda crossing and hope. Twelve nights is a long time to be wrong about yourself.
Frequently asked questions
Do most people get seasick on a phinisi?
No. Most guests are fine, particularly on the sheltered Komodo and Dampier Strait itineraries where the boat is at anchor for most hours.
Is a phinisi more stable than a speedboat?
Generally, yes. The roll is slower and deeper, which most people find easier than a light hull’s sharp motion.
When should I take medication?
Before departure, on the schedule your pharmacist or doctor advises. Taken after symptoms start, most remedies are far less effective.
Can I dive if I have taken seasickness medication?
Discuss it with your doctor first. Some remedies cause drowsiness, which matters underwater. Tell your dive guide what you have taken.
Which cabin is best if I am prone to motion sickness?
Lower deck, amidships. Avoid the bow, and avoid the upper deck on exposed routes.
Does the boat move at anchor?
Gently, and most people sleep well. Anchorages are chosen for shelter.
What should I eat if I feel unwell?
Something plain and dry, in small amounts. An empty stomach is worse than a light one, and the crew will always have crackers, rice and ginger tea.
Will the captain change the route if I struggle?
Within safety and schedule limits, yes — timing, heading, anchorage. Say something early rather than enduring it quietly.

Charters are operated by Komodo Luxury, part of Juara Holding Group, sailing Indonesian waters since 2015. If anyone in your party is seriously prone to motion sickness, say so at enquiry — we will steer you to a sheltered itinerary, put them in the right cabin and brief the crew before you step aboard.
