What to Pack for Thailand for Ferry and Boat Travel: Dry Bags, Motion-Sickness Gear, and Waterfront Essentials

We’re shoulder to shoulder on a sun-baked pier, diesel fumes curling in the air, waves slapping the concrete, porters shouting “Samui! Phangan! Tao!” A squall smudges the horizon while a longtail thumps past, misting us with warm spray. This is the moment when a smart Thailand ferry packing list pays off—when your passport stays dry, your stomach stays settled, and your phone doesn’t go for a swim.

Thailand Ferry Packing List: The Essentials

If we pack nothing else, these are non-negotiables for any ferry, speedboat, or river hop in Thailand.

• Travel documents and tickets: Passport, visa-on-arrival slip, and ferry confirmations (screenshots—piers sometimes have spotty signal). Some operators require you to check in at a counter for a paper sticker. Leave 20–30 minutes to swap digital for physical.
• Cash (small notes): 20–100 baht notes for pier fees (some islands collect 20–40 baht on arrival), porters (20–50 baht per bag if you use them), snacks, and songthaews at the other end. Many boats and piers are cash-only.
• Phone power: A 10,000–20,000 mAh power bank and a short cable you can use one-handed while holding a railing. Big ferries sometimes have outlets, but don’t count on them.
• Waterproof storage: A 10–20L dry bag for carry-on essentials, plus a universal waterproof phone pouch. Zip-top bags (1–3L) for passports and paper tickets. We keep a spare dry sack for surprise downpours.
• Quick-access day bag: Even if the crew stows your backpack in the hold, keep meds, water, chargers, and documents with you.
• Refillable water bottle: Fill at your guesthouse; top up at {{place:7-Eleven:text}}. Dehydration sneaks up fast in sea breeze and sun.
• Snacks: Fruit, sticky rice, or a 7‑Eleven onigiri—cheaper than boat kiosks and handy if the water gets choppy.

Tip: Screenshot the pier map and your accommodation’s address in Thai. After we dock, a tuk‑tuk driver on Thong Sala or Tonsai will appreciate not deciphering farang phonetics.

Clothing and Comfort for Heat, Spray, and Freezer-AC

The Andaman and the Gulf can flip from sauna to icebox in a minute—sun outside, arctic AC inside.

• Quick-dry top and shorts: Synthetic or merino beats cotton when sea spray hits.
• Light long-sleeve or sun hoodie: SPF fabric keeps shoulders from frying on the top deck.
• Packable rain poncho: 20–40 baht from 7‑Eleven saves you and your pack during surprise squalls.
• Warm layer: A thin hoodie or sarong for overachieving AC in cabins (looking at you, Don Sak–Samui lines).
• Deck-friendly footwear: Rubber-soled sandals or water shoes. Flip-flops are fine, but slick steel stairs demand grip.
• Hat and polarized sunnies: For glare and spray. Add a retainer strap so your shades don’t join the fish.
• Light scarf or sarong: Sun cover, headrest, makeshift pillow, modesty layer if you conk out in the aisle.
• Compact towel: A quick-dry face towel for sweat and salt; full-size if you’re transferring to a longtail straight to the beach.

If you’re hopping Bangkok boats—the Chao Phraya Tourist Boat ICONSIAM Pier or khlong boats off Saen Saep—dress like you’re going to get splashed. We hug the rail, shades on, and try not to inhale canal water. Sanuk, but spicy.

Safety and Motion-Sickness Basics

We love a glassy crossing, but Thailand’s seas have moods. Prep the body as well as the bag.

• Motion-sickness meds: Dimenhydrinate or meclizine (Boots, Watsons, and many 7‑Elevens) taken 30–60 minutes before departure. Ginger chews or capsules help too.
• Hydration & electrolytes: Pack a sachet or grab Sponsor/Pocari from any 7‑Eleven. Sip, don’t chug.
• Sunscreen (reef-safer if you’re beach-bound): Reapply. Boat wind is a sneaky burn partner.
• Lip balm with SPF: The salt-air crack is real.
• Small first-aid: Plasters, ibuprofen, antiseptic wipes, rehydration salts. Boats carry basics, but not always what you like.
• Earplugs and eye mask: For naps, or if you end up on an overnight slow boat with snorers and fluorescent lights.
• Seasick strategy: Top deck + horizon gaze works for some. Midship seats near the centerline bounce less. Avoid heavy meals and diesel-heavy corners.

Protecting Valuables and Electronics

Piers are chaotic. Decks are wet. Longtails love a hard stop that sends loose items skating.

• 10–20L dry bag: Bright color, roll-top, shoulder strap. Big enough for wallet, phone, camera, hoodie, and snacks.
• Waterproof phone case: Lanyard looped to a carabiner on your bag. We keep the camera accessible but tethered.
• Organization pouches: One for tech (power bank, cables), one for docs (passport, tickets), one for meds. Different colors so you can grab without rummaging.
• Silica gel packs: Toss a couple in your camera pouch to fight humidity.
• Carabiners: Clip dry bag to railings or seat frames when you nap so it doesn’t slide.
• Small cable lock: Useful if luggage is stacked in the hold; loop through zips and a frame for peace of mind.
• Minimal wallet: ID copy, 1 ATM card, 1 credit card, 1,000–2,000 baht in small notes. Keep the bulk stash deep in your main pack.

Crowded landings—like Tonsai Pier (Phi Phi) at midday or Thong Sala (Koh Phangan) pre-Full Moon—are where phones “walk.” We stow the selfie routine until we’re clear of the scrum.

Route-Specific Packing Tips Across Thailand

Ferries aren’t one-size-fits-all. The Gulf of Thailand and the Andaman Sea each have their quirks, seasons, and ship styles.

Don Sak–Samui/Phangan (Surat Thani side)

• Expect big roll-on ferries with cold AC lounges and open decks. Hoodie and dry bag are musts.
• Monsoon chop is most likely Nov–Jan; crossings still run, but meds help.
• On Koh Samui, taxis at Nathon Pier can be pricey. Small notes help with songthaews; confirm the fare before you climb aboard.

Chumphon/Surat Thani–Koh Tao

• Speedboats can be bumpy on windy days. Secure sunglasses and hats; sit midship if you’re nausea-prone.
• Night boats/sleepers run on some routes—earplugs, sheet liner, and a hoodie shine here. More overnight specifics in our guide: What to Pack for Thailand for Overnight Ferry and Boat Travel: Sleep, Security, and Dry Bags.

Phuket–Phi Phi–Krabi–Lanta (Andaman side)

• Rassada Pier (Phuket) mornings are mayhem; label your big bag. Andaman monsoon (roughly May–Oct) can mean spray-heavy decks; dress to get wet.
• Arrival at Tonsai (Phi Phi) often includes a small local “cleaning fee” and a gauntlet of touts. Keep your day bag zipped and your smile polite.

Trat–Koh Chang / Koh Kood / Koh Mak

• Shorter car ferries to Koh Chang from Ao Thammachat mean salty mist, quick rides, and immediate transfers to songthaews. Keep cash and hotel address handy.
• Koh Kood/Koh Mak speedboats unload onto floating piers or beaches—water shoes and a towel earn their keep.

Bangkok Boats: Chao Phraya and Khlongs

• Different vibe, same rules: splash-prone, crowded, fast. Keep your phone lanyarded, small change ready (16–30 baht fares), and your bag front-facing in crowds.

Know Before You Go: Tickets, Timing, and Piers

A few logistics we’ve learned the sweaty way.

• Arrive early: 30–45 minutes before departure lets you swap vouchers for stickers, tag your bag, and grab shade. For popular midday crossings in high season (Dec–Apr), aim for 60 minutes.
• Bag handling: Staff often stack big backpacks near the bow or in the hold. Remove valuables first. Mark your bag with a bright strap so it’s easy to spot at pickup.
• Pier fees and national park fees: Some islands collect small local fees (20–40 baht). National park areas (e.g., parts of the Phi Phi archipelago) may charge higher entry fees—usually paid on arrival by cash.
• Transfers: Joint tickets may include a bus/minivan leg to/from the pier (e.g., Surat Thani airport to Don Sak). Keep the sticker visible; it’s your golden ticket.
• Weather windows: Andaman (Phuket/Krabi) is calmest Nov–Apr. The Gulf (Samui/Phangan/Tao) is calmest Jan–Apr and can see rougher seas in Nov–Jan. Boats still run; just pack like the sky could change its mind.
• Scams and “helpful” porters: Official staff wear company polos and handle stickers. If anyone rushes you toward a “special” taxi, sawadee with a smile and keep moving to the public queue.
• Data and signal: AIS/True/dtac have decent pier coverage, but dead zones exist offshore. Download offline maps and hotel instructions before boarding.

Bonus Gear That Punches Above Its Weight

• Compact bungee or luggage strap: Tames a wobbly tower of bags.
• Lightweight dry box (hard case) for cameras/drones if you’re speedboating in monsoon season.
• Anti-theft crossbody with lockable zippers for crowded piers.
• Collapsible tote: For beach transfers where your big pack rides in a separate longtail.
• Travel detergent sheet and a few pegs: Salt spray funk is real—rinse and air-dry overnight.

Packing It All: Our Ferry-Day Loadout

When we head from Soi Rambuttri to the southern islands, this is what actually goes on our backs:

• On-body: Passport in a zip pouch, minimal wallet, phone in a waterproof lanyard, polarized shades with strap, hat, SPF lip balm.
• Day bag (10–20L dry bag): Power bank + cable, motion-sickness tablets, ginger chews, 1L water, electrolytes, hoodie, poncho, face towel, snacks, spare mask, small first-aid, silica packs, carabiners, cable lock, photocopies of ID.
• Main pack (checked/stacked): Clothes in packing cubes, extra zip-tops, spare sandals, light laundry kit, reef-safer sunscreen, mosquito repellent. We lock the zips and keep nothing valuable inside.

Final Word From the Pier

Bangkok to the islands is a rite of passage, whether we roll out from Khao San Road at dawn, weave past the Golden Mount, and catch a minivan south—or just hop a Chao Phraya boat for sunset. Pack like you’ll get splashed, chilled, and sun-kissed in the same hour. Keep your docs dry, your stomach steady, and your sense of sanuk handy. We’ll grab a cold Sponsor at the pier and race you to the top deck for that first sea breeze.
