Seasickness on Liveaboards: Prevention and Remedies
Let's talk about the thing no one wants to discuss: spending your dream dive trip wishing for death in your cabin while the ocean mocks you.
Seasickness is real. It's common. And it's manageable — if you prepare.
The Science (Quick Version)
Motion sickness happens when your inner ear (which senses motion) disagrees with your eyes (which see stable surroundings). Your brain gets confused, and your body responds by making you miserable.
On a boat, the motion is constant but the cabin looks stable. Confusion ensues.
Prevention: Start Before You Board
Medication Options
Dramamine/Bonine (dimenhydrinate/meclizine): Over-the-counter, effective, can cause drowsiness. Start 1-2 hours before boarding.
Scopolamine patches: Prescription in most countries. Apply behind the ear 6-8 hours before boarding. Lasts 72 hours. Very effective for most people.
Stugeron (cinnarizine): Not available in the US, but popular elsewhere. Works well, less drowsy than Dramamine.
Ginger: Natural option. Ginger candies, capsules, or real ginger root. Evidence is mixed, but no side effects.
The critical rule: Take medication BEFORE you feel sick. Once nausea starts, pills often come back up before they work.
On the Boat
Position Matters
- Stay on deck when possible — fresh air and horizon views help
- Mid-ship, lower decks have less motion
- Avoid the bow in rough conditions (maximum up-and-down)
- Face forward when possible
Behavioral Tips
- Watch the horizon — gives your brain a stable reference
- Stay busy — distraction helps (but not with screens)
- Avoid reading or staring at your phone
- Eat light but eat — empty stomachs are worse
- Stay hydrated — dehydration makes everything worse
- Avoid alcohol the night before and during rough crossings
What to Avoid
- Strong smells (diesel, cooking odors, perfume)
- Heavy, greasy meals
- The cabin during the day (if possible)
- Other seasick people (it's contagious psychologically)
When It Hits Anyway
If prevention fails:
- Get outside — fresh air is medicine
- Watch the horizon — even if you feel terrible
- Stay horizontal — lying down reduces symptoms
- Sip water or ginger ale — small amounts
- Use acupressure bands — some people swear by them
- Wait it out — most people acclimate in 24-48 hours
The Diving Paradox
Here's the weird truth: you often feel better underwater. The motion doesn't penetrate, and you're focused on other things.
Many seasick divers live for the dives and endure the surface intervals. It's not ideal, but it works.
When to Worry
Severe, prolonged seasickness can cause dehydration and electrolyte imbalance. If you:
- Can't keep fluids down for 12+ hours
- Feel faint or extremely weak
- Have severe headache or confusion
Tell the crew. They've seen it before and can help.
The Good News
Most people acclimate. Day one might be rough. Day two gets better. By day three, you're usually a seasoned sailor.
And the diving? Worth every uncomfortable moment.
