There is a moment on every liveaboard journey when you realise that life on land feels far away. The sun sets behind the Andaman Sea, tanks are filled for the next dive, and the hum of the generator becomes the soundtrack to a world that revolves around diving. For those setting sail aboard the Blue Dolphin Liveaboard in Thailand, that moment arrives quickly. Purpose-built for comfort and designed around the needs of divers, this vessel has become one of the most respected liveaboard experiences operating from Khao Lak.
A Purpose-Built Vessel for Comfort and Adventure
The Blue Dolphin measures around 27 metres and comfortably accommodates up to sixteen guests, creating an atmosphere that is both intimate and personal. Refitted in 2022, the vessel combines modern facilities with a warm, dive-focused environment. Each air-conditioned cabin has been thoughtfully designed, offering a mix of master, twin, and shared configurations to suit different budgets. A generous dive deck makes equipment setup effortless, while the shaded upper deck provides space to unwind between dives. Nitrox is available for those who prefer extended bottom times, and certification courses can be completed onboard under the guidance of experienced instructors.
Reviews from guests consistently praise the Blue Dolphin for its attentive service, exceptional food, and professional crew. Many divers describe the experience as joining an extended family at sea, with staff who go above and beyond to make every dive smooth, safe, and memorable.

Gateway to Thailand’s Diving Paradise
Operating from Khao Lak, the Blue Dolphin offers access to some of the best dive sites in the Similan and Surin Islands National Parks. The region sits along Thailand’s west coast in the Andaman Sea and has long been regarded as one of the top diving destinations in Asia. The season typically runs from October through May, when calm seas, warm water, and exceptional visibility create ideal diving conditions.
Khao Lak itself is a quiet and charming town north of Phuket, offering a relaxed pre- and post-trip base. It blends authentic Thai culture with modern dive infrastructure, making it easy for guests to prepare for their voyage or wind down after returning from sea.
The Journey at Sea
The Blue Dolphin’s itineraries usually run for four to five days, departing from Tab Lamu Pier and heading west toward the open Andaman. The first night sets the tone for adventure as guests wake to the sight of the Similan Islands emerging on the horizon. Each day brings three to four dives, spread across reefs, pinnacles, and wrecks that showcase the full diversity of Thailand’s marine life.
The pace is relaxed yet immersive. Between dives, divers lounge on the upper deck, enjoy freshly prepared Thai meals, or review photos in the air-conditioned salon. Evenings often bring quiet sunsets and easy conversation under the stars, a rhythm that quickly becomes addictive.
Dive Highlights of the Andaman Sea
Few dive destinations offer the variety found along the Blue Dolphin’s route. Among the most celebrated sites is Richelieu Rock, a horseshoe-shaped pinnacle that draws divers from around the world. Its vibrant soft corals are home to harlequin shrimp, seahorses, and countless reef fish, while larger visitors such as whale sharks and barracuda occasionally make an appearance.
Koh Bon is renowned for its manta ray cleaning stations, where divers can hover in midwater as the gentle giants glide past. Further north, Koh Tachai Pinnacle delivers exhilarating dives with swirling schools of trevally, tuna, and the occasional leopard shark.
Within the Similan Islands, sites such as West of Eden, Elephant Head Rock, and Boulder City reveal a striking underwater landscape of granite formations, coral gardens, and sweeping swim-throughs. Each dive site has its own character: some ideal for photography, others perfect for slow exploration. The Boonsung Wreck, often saved for the final day, offers a completely different experience as divers weave through the remains of a former tin dredger now carpeted in soft corals and schooling fish.
Marine Life and Underwater Landscapes
The Andaman Sea is famous for its biodiversity. Divers can expect encounters with turtles, octopus, cuttlefish, and countless species of reef fish on almost every dive. Macro enthusiasts are rewarded with sightings of nudibranchs, ornate ghost pipefish, and tiny crabs hidden among the corals. Wide-angle photographers, on the other hand, find inspiration in the dramatic seascapes, coral bommies, and the occasional pelagic passing through.
Because the Blue Dolphin visits sites early and stays overnight within the national parks, divers often enjoy quiet reefs before day boats arrive. This exclusive access not only enhances the experience but also helps protect fragile ecosystems by reducing crowding.
Professionalism and Safety at Sea
The professionalism of the Blue Dolphin team is often highlighted by returning guests. Dive briefings are detailed and approachable, blending safety with enthusiasm. Guides are skilled at managing a range of diver experience levels, from those newly certified to seasoned professionals seeking adventure. With small dive groups and clear organisation, every diver receives the attention they need while maintaining a sense of independence underwater.
Nitrox availability allows for safer and longer dives, and those wishing to expand their knowledge can complete additional training during the voyage. Equipment is well maintained, and the crew’s familiarity with the region ensures that every dive is conducted responsibly within park regulations.
Beyond the Dive Deck
A liveaboard trip is about more than the dives themselves. Life onboard follows an easy rhythm that connects divers with the sea in a way day trips never can. Meals are freshly prepared using local ingredients, blending Thai flavours with international favourites. The sundeck becomes a social space, perfect for reading, resting, or simply gazing across the water. At night, the stars stretch across the sky, uninterrupted by city lights, creating moments of quiet reflection that stay long after returning to shore.
Why Blue Dolphin Stands Out
The Blue Dolphin strikes an ideal balance between comfort, value, and world-class diving. It avoids the excess of ultra-luxury yachts yet delivers a standard far above the average dive vessel. The combination of attentive crew, excellent cuisine, and access to iconic dive sites like Richelieu Rock and Koh Bon makes it one of the strongest choices for divers exploring Thailand.
Its manageable group size ensures personal attention, while itineraries are crafted to showcase the best of the Andaman without rushing. Every element, from dive logistics to the relaxed atmosphere onboard, is designed to let divers focus on what matters most — the ocean.
The Essence of Diving Thailand
For divers seeking the perfect blend of adventure, comfort, and authenticity, the Blue Dolphin captures the essence of Thailand’s diving spirit. It offers clear water, thriving reefs, friendly professionalism, and the simple joy of waking each morning surrounded by open sea.
Whether it is your first liveaboard or your fiftieth, few experiences match the satisfaction of watching the sun rise over the Similan Islands from the deck of the Blue Dolphin, ready for another day beneath the surface.
