Seasickness on a Komodo Liveaboard — Prevention, Care & When to Worry

Travel Health Guide · Part of our Labuan Bajo & Komodo Travel Health Guide · Medically reviewed by dr. M. Candra Wijanadi, M.M. · Last updated: September 2026.

Most Komodo trips involve at least one day, and often two or three nights, on a boat — and open water between islands means real swell. Seasickness is one of the most common reasons travelers contact us during a liveaboard trip. It's rarely dangerous on its own, but it's worth knowing how to prevent it, what helps once it starts, and the point where it's no longer just seasickness.

Why It Happens

Motion sickness happens when the movement your inner ear senses doesn't match what your eyes see — for example, feeling the boat roll while your eyes are fixed on a still cabin interior. It typically causes dizziness, nausea and vomiting, and while unpleasant, it's not itself a serious condition.

Before You Board: Prevention

• Medication in advance — motion sickness tablets (such as dimenhydrinate) work best taken before symptoms start, not after. Ask a doctor or pharmacist what's suitable for you.
• Choose your cabin if you can — a central, lower cabin moves less than one at the bow or stern.
• Eat lightly beforehand — avoid heavy or greasy food right before boarding.
• Ginger — ginger candy or tea is a commonly used, low-risk option some travelers find helpful alongside other measures.

On the Boat: What Helps in the Moment

• Stay on deck in fresh air rather than below deck.
• Keep your eyes on a fixed point on the horizon rather than a phone, book or screen.
• Lie down if you can, in a central part of the boat.
• Sip water regularly, even if you don't feel thirsty — this matters more than it seems, see below.

When It's More Than Seasickness — Dehydration Warning Signs

Ordinary seasickness settles once the boat is calmer or you're back on land. The concern is when repeated vomiting stops you from keeping any fluids down for an extended period. Watch for:

• Unable to keep water down for several hours
• Very dark urine, or not urinating
• Extreme dizziness, confusion or fainting
• A noticeably fast heartbeat

Any of these are a reason to get medical help rather than wait it out, especially on a multi-day trip where you may not reach a port for a while.

Where IV Drip Therapy Fits In

An IV drip doesn't stop motion sickness itself — it doesn't address the inner-ear cause. What it does is rehydrate you quickly and replace electrolytes lost through vomiting, which is genuinely useful once you're dehydrated, and can make recovery noticeably faster once you're back on land or at anchor. It's a treatment for the dehydration that seasickness can cause, not a cure for the seasickness itself. Our doctor-led IV drip packages are available at the clinic, or we can come to your liveaboard's port or anchorage — see IV Drip Therapy for package details.

Getting a Doctor to Your Boat

If you're too unwell to leave the boat, message us with your vessel's planned port call or anchorage and we'll arrange a doctor on call to assess you, including IV rehydration on site if needed.

Frequently Asked Questions

Can an IV drip cure seasickness?

No — an IV drip doesn't stop motion sickness itself, which is caused by a mismatch between what your inner ear and eyes sense. What it helps with is rehydration and replacing lost electrolytes after repeated vomiting.

What's the best position on a boat if I get seasick easily?

Stay on deck rather than below, in a central, lower part of the boat, and keep your eyes on a fixed point on the horizon rather than a phone screen.

How do I know if it's more than normal seasickness?

Warning signs include being unable to keep fluids down for several hours, very dark urine, extreme dizziness or confusion, or a rapid heartbeat — these are a reason to get medical help.

Can a doctor come to my liveaboard if I'm too sick to get to a clinic?

Yes — message us on WhatsApp with your boat's planned port or anchorage and we can arrange a doctor on call, including IV rehydration if needed.
