You've decided to do the 4 Islands Tour in Krabi. Smart move — it's one of the best days you can have in southern Thailand. But now comes the question that trips up almost every first-time visitor:
Speedboat or longtail boat?
Both get you to the same four islands — Chicken Island, Tup Island, Poda Island, and Phra Nang Cave Beach. But the experience on the water, the time you spend at each stop, the price you pay, and even the photos you take home are surprisingly different.
This guide breaks it all down honestly so you can choose in 5 minutes and get on with booking.

Choose speedboat if: you want more time on the islands, travel with young kids, or are prone to seasickness.
Choose longtail if: you want an authentic Thai experience, love the iconic wooden boat photos, and prefer a slower, more relaxed pace.

What Is a Longtail Boat?
A longtail boat is the wooden vessel you've seen in every Krabi postcard. Long, narrow, and brightly painted, it's powered by a car engine mounted on a long pole extending out from the stern — hence the name. These boats have been the transport backbone of Thai coastal communities for generations.
On the 4 Islands Tour, the longtail departs from Nopparat Thara Pier in Ao Nang. The engine is loud (bring earplugs if you're sensitive), there's no roof over most of the boat, and you'll feel the waves. But there's something undeniably magical about cruising the Andaman Sea in one of these boats with the limestone cliffs rising around you.
Longtail boat price: from ฿850 per person (including mini buffet lunch, snorkeling gear, life jacket, and hotel transfer)
What Is a Speedboat?
The speedboat on the 4 Islands Tour is a modern fiberglass vessel with two or three powerful outboard engines. It seats more passengers, has a partial canopy for shade, and cuts travel time between islands by roughly two-thirds compared to a longtail.
You'll feel the speed — at full throttle, speedboats bounce across waves, which some people love and others find uncomfortable. But the payoff is more time at each island stop rather than on the water between them.
Speedboat price: from ฿1,100 per person (including mini buffet lunch, snorkeling gear, life jacket, and hotel transfer)
The price difference is only ฿250 per person — roughly the cost of a Chang beer. For most people, that's not the deciding factor.
5 Key Differences Explained
1. Time on the Islands vs Time on the Water
This is the most practical difference and often the deciding one.
Longtail boats travel at around 20–25 km/h. Speedboats hit 50–60 km/h. Between the four island stops, that difference adds up to roughly 60–90 extra minutes on the water if you take a longtail.
Both tours run approximately 6–7 hours total. But with a speedboat, more of that time is spent swimming, snorkeling, and walking the Tup Island sandbar — not sitting on the boat watching the destination slowly get closer.
If seeing the islands and maximizing beach time is your priority, the speedboat wins here.
2. Seasickness
The Andaman Sea is generally calm from November to April, but swells can pick up — especially in the shoulder months of May and October. Longtail boats sit lower in the water and are more affected by chop. The rocking motion on longer crossings between islands can be rough if you're prone to motion sickness.
Speedboats ride higher and cut through waves rather than riding over them. They're faster so you're on the water for less time. Most seasick-prone travellers report a much better experience on speedboats.
Verdict: speedboat is significantly better for anyone who gets seasick.
3. The Experience and Atmosphere
Here's where the longtail boat earns its fans. There's a reason these wooden boats appear in every photo of Krabi — they're visually stunning. Arriving at Phra Nang Cave Beach or gliding toward the Tup Island sandbar on a longtail, with the engine puttering and the limestone cliffs looming overhead, feels genuinely Thai in a way that a fiberglass speedboat simply doesn't.
The longtail also tends to carry fewer passengers, which means a quieter, more intimate feel. You'll have a guide, but it's a less packaged experience.
Speedboats, by contrast, carry larger groups and have a more "tour" feel — organised, efficient, but less romantic.
Verdict: longtail wins on atmosphere and authenticity.
4. Photos
Both boats produce stunning photos — you're surrounded by some of the most photogenic scenery in Southeast Asia. But the type of photos differs.
The longtail boat itself is incredibly photogenic. Shots of the colourful wooden bow, the long engine pole trailing behind, and the turquoise sea stretching to limestone cliffs are classic Krabi images. If Instagram-worthy boat photos matter to you, the longtail delivers.
For snorkeling and underwater shots, both boats stop at the same locations with the same quality of reef access.
Verdict: longtail for boat photography; equal for island and underwater shots.
5. Comfort and Shade
Longtail boats have minimal shade — most passengers sit in the open under the Thai sun. For a 6-hour day on the water, that's significant. Bring SPF 50 and a hat regardless of which boat you choose, but longtail riders need to be especially prepared.
Speedboats have a partial canopy over the seating area. It doesn't shade everyone, but it provides some relief during crossings.
Verdict: speedboat is more comfortable, especially in peak heat (February–April).
Who Should Book Each Option?
Book the Speedboat if you are…
- Travelling with young children who get bored or tired easily
- Prone to seasickness or motion sickness
- Visiting during peak sun months (January–April) and want shade
- Focused on maximizing island time for swimming and snorkeling
- On a tight schedule and want the most efficient day
Book the Longtail Boat if you are…
- Looking for an authentic Thai experience on the water
- A photographer who wants the iconic Krabi boat shots
- Travelling as a couple or small group who prefers a quieter, more intimate tour
- Budget-conscious (though the ฿250 difference is small)
- Someone who loves a relaxed pace and doesn't mind more time on the water
What About Seasickness? Practical Tips
Whether you choose speedboat or longtail, here's how to manage if you're prone to motion sickness:
- Take medication before you board — Dramamine or Bonine, taken 30–60 minutes before departure, work well for most people
- Sit in the middle of the boat, not at the front or back — this is where you feel the least motion
- Look at the horizon, not at the water directly below or a screen
- Avoid a heavy breakfast — something light 1–2 hours before departure is ideal
- Stay hydrated — dehydration makes nausea worse
- Choose the speedboat if you have any doubts — shorter time on the water is the single biggest factor

Our Honest Recommendation
For most visitors to Krabi in 2026, the speedboat is the better choice — not because the longtail is bad, but because more beach time, better comfort in the heat, and significantly lower seasickness risk make for a more enjoyable day for the majority of travellers.
That said, if you're a couple looking for that classic Krabi experience, enjoy a slower pace, and have your sea legs, the longtail boat offers something the speedboat simply can't: the feeling that you're actually in Thailand, not just being efficiently transported through it.
The good news? Either way, the four islands themselves are spectacular. The sandbar at Tup Island, the coral reefs at Chicken Island, the white beach at Poda, and the limestone drama of Phra Nang Cave Beach look just as beautiful from both boats.
