Most liveaboards anchor in sheltered bays at night. Long open-ocean crossings can be rough — bring patches or pills if you're prone to motion sickness.
Seasickness is the single most common physical complaint on liveaboards
Even experienced sailors can be caught out by an unusual swell or a long open-ocean transit. The good news is that almost everyone adjusts within 24–48 hours and the second half of the trip is usually fine.
Where seasickness is rarely a problem
Mainstream tropical destinations with sheltered itineraries — Maldives atolls, northern Red Sea coastal routes, Bahamas reef, Cayman Islands, Honduras Bay Islands. Boats anchor in protected bays each night and movements between sites are short (1–3 hours). Most divers feel nothing.
Where seasickness is sometimes a problem
Indonesia (Komodo, Banda Sea, Raja Ampat — long inter-island crossings), Egyptian offshore Brothers and Daedalus (overnight crossings to remote pinnacles), Caribbean wreck routes with longer transits, Sea of Cortez when winds pick up.
Where seasickness is a real consideration
Galápagos crossings to Wolf and Darwin (12–16 hours each way through open Pacific), Costa Rica to Cocos Island (30+ hours each way), Cabo San Lucas to Socorro (24–28 hours each way), Australian Coral Sea expeditions, Antarctic/Sub-Antarctic crossings of the Drake Passage. On these trips, expect significant motion during the crossing legs and bring serious medication.
Medication options
Scopolamine patches (Transderm Scop) are the gold standard — applied behind the ear 4 hours before sailing, last 72 hours. Available on prescription in most countries. Side effects include dry mouth and drowsiness. Cinnarizine (Stugeron) is over-the-counter in Europe and very effective with fewer side effects than dimenhydrinate. Bonine (meclizine) and Dramamine (dimenhydrinate) are over-the-counter in the US. Take all medications according to label directions and ideally do a test run at home before the trip.
Non-medication strategies
Stay topside in fresh air during crossings. Look at the horizon, not at your phone or a book. Stay hydrated (dehydration worsens motion sickness). Eat light meals; avoid greasy food and alcohol the night before a known crossing. Ginger (in tea, capsules or candies) helps some people. Pressure-point wristbands (Sea-Bands) work for some, placebo for others.
Cabin choice
Lower-deck and midship cabins move least and are best for prone passengers. Upper-deck and bow cabins move most. If seasickness is a concern, request a midship cabin at booking.
