Longtail Boat Tours: The Authentic Thai Experience

February 13, 2026 9 min read By Samui Authentic Team

Nothing says "Thailand" quite like gliding across turquoise waters aboard a traditional longtail boat. With their distinctive long propeller shafts, colorful ribbons, and the rhythmic hum of their engines, longtail boats are an icon of Thai maritime culture. At Samui Authentic, our fleet of 6 longtail boats offers one of the most authentic ways to explore Koh Samui's surrounding islands.

What Is a Longtail Boat?

A longtail boat — called ruea hang yao in Thai — is a traditional wooden vessel powered by a modified automotive engine mounted on a long rotating shaft that extends beyond the stern. The propeller sits at the end of this shaft, which the captain can lift, lower, and pivot to navigate shallow waters and tight spaces that larger boats simply cannot reach.

These boats are typically 8 to 12 meters long, hand-built from hardwood, and adorned with colorful scarves and flower garlands at the bow — offerings to the spirit of the sea. The design has remained essentially unchanged for generations, though engines have replaced traditional sails.

A Brief History of Longtail Boats

Longtail boats have been the backbone of Thailand's coastal communities for over a century. Originally designed for fishing in the shallow waters of the Gulf of Thailand and the Andaman Sea, they evolved from simple sailboats into engine-powered craft in the mid-20th century when fishermen began repurposing car and truck engines for marine use.

On Koh Samui, longtails were the primary means of transportation between islands before modern ferries and speedboats arrived. Fishermen, traders, and families relied on them daily. Today, while the fishing tradition continues, many longtail captains also share their knowledge of the sea with visitors — offering an experience that connects you directly to centuries of Thai seafaring heritage.

Our Fleet: 6 Longtail Boats

Samui Authentic operates a fleet of 6 traditional longtail boats, each with a capacity of up to 10 passengers. Our boats are maintained to high safety standards while preserving their authentic character. Each vessel is captained by an experienced local fisherman who knows every cove, reef, and hidden beach around Koh Samui.

Having 6 boats means we can accommodate multiple groups simultaneously and offer private charters even during peak season. Whether you are a couple seeking a romantic sunset ride or a family of 10 wanting a full-day island adventure, we have a boat ready for you.

Where Can You Go by Longtail?

Longtail boats are ideal for exploring the islands closest to Koh Samui. Their shallow draft lets them pull right up to beaches that speedboats can't approach, and their slower pace makes the journey itself part of the experience.

Koh Tan & Koh Madsum (Pig Island)

Our most popular longtail destination. Koh Tan offers pristine coral reefs for snorkeling, while Koh Madsum is famous for its friendly free-roaming pigs on the beach. The crossing from Koh Samui takes only 15-20 minutes by longtail, and the calm waters make it perfect for families. From 2,800 THB per person on a shared tour.

Koh Rap

A small uninhabited island southwest of Koh Samui, Koh Rap is our best-kept secret. We run a unique BBQ experience where the captain grills freshly caught seafood on the beach while you swim and snorkel in crystal-clear water. Accessible only by longtail, which adds to its exclusivity. From 3,500 THB per person.

Coastal Exploration

Longtails are perfect for exploring Koh Samui's coastline — hidden coves, secluded beaches, and fishing villages that you'd never discover from land. A half-day coastal cruise with swimming stops is one of the most relaxing ways to spend a morning in Samui.

Longtail vs Speedboat: Which to Choose?

Both types of boats have their place. Here's an honest side-by-side comparison to help you decide:

Criteria Longtail Boat Speedboat
SpeedSlow & relaxed (10-15 km/h)Fast (40-60 km/h)
RangeNearby islands (Koh Tan, Koh Rap)Any island (inc. Ang Thong)
PriceMore affordableHigher price point
ExperienceTraditional, immersive, photogenicModern, comfortable, efficient
CapacityUp to 10 passengers10 or 20 passengers
Shallow water accessExcellent — can beach directlyLimited — anchors offshore
Best forShort trips, authentic feel, budgetFull-day trips, distant islands

Why Choose a Longtail

  • Authentic Thai experience you can't get elsewhere
  • More affordable than speedboat tours
  • Access to shallow beaches and hidden coves
  • Quieter, more relaxing pace
  • Incredible photos — longtails are iconic
  • Supports local fishermen-captains directly

When a Speedboat Is Better

  • For distant destinations like Ang Thong Marine Park
  • In rougher sea conditions
  • If you want more onboard comfort
  • For groups larger than 10 people

Tips for Your Longtail Boat Tour

  1. Bring waterproof protection for your phone and camera. Longtails ride lower in the water than speedboats, and sea spray is part of the charm.
  2. Wear reef-safe sunscreen — you'll be visiting coral reefs, and chemical sunscreens damage marine life. We provide snorkeling equipment but not sunscreen.
  3. Best season: December to April offers the calmest seas and best visibility. But longtail tours run year-round on suitable days — our captains know when conditions are right.
  4. Bring cash for any additional stops at local restaurants or shops on the islands. Most island vendors don't accept cards.
  5. Book a morning departure for the best snorkeling visibility and calmer seas. Afternoon trips can be beautiful for photography as the light softens.
