The SeaWorld 1 liveaboard offers year-round diving in Thailand (Similan, Surin, Phi-Phi) and Myanmar (Mergui Archipelago). SeaWorld 1 caters to 18 guests in 9 cabins. On the main deck are 3 en-suite double-bed master cabins (with private bathrooms) and 2 double-bed master cabins. On the upper deck, there are 4 bunk-bed cabins. All rooms feature individually controlled AC and storage space. The upper deck has a lounge area with a TV, DVD, and a sound system. There is also a spacious sun deck with bean bags and beach beds, perfect for relaxing between dives. During the day, the chef serves 4 delicious meals of authentic Thai and international food. Tea, coffee, soft drinks, snacks, and water are provided throughout the day.

SeaWorld 1 has several multi-day itineraries. Typical 5-day/4-night trips sail to the northern Andaman, such as Similan Islands and Richelieu Rock, offering a variety of diving experiences - deep to shallow, wall to reef, and macro to wide-angle photography. Get lucky with Whale Sharks, Mantas, Leopard sharks, and more exotic marine life. The 6/7-day trips take place in the Mergui Archipelago in Myanmar. Myanmar only recently opened its waters in the late 1990s after being closed for over 50 years. Few divers have seen this untouched reef since only a few dive boats are there.

Well organised and executed getting the best from the week
Diving close to whale sharks. Variety of great dive sites with interesting topography. Being shown seahorses. The non-diving day, relaxing on a remote island, snorkelling in the volcanic crater. The mango and coconut milk 'snack.

Safety the top concern by all crew and dive masters. Calm weather throughout. I was lucky enough to get my own cabin, due to the way the numbers fell.

First Liveaboard
We really enjoyed our trip to Similan. The crew was very nice and we got the best food we ate in Thailand four times a day. The dive site Richelieu Rock was our highlight. We even saw a whale shark. We highly recommend this tour. The price-performance ratio is amazing and the tour is suitable for every diving level.

Very nice liveaboard
It was a lot of fun to travel with the Seaworl 1. The crew is super nice and helpful. Despite strong waves in the meantime, diving spots were selected that were good to dive.It was dived in small teams and since the boat cannot accommodate as many passengers as others, fortunately it was not mass processing.The boat itself is clean and completely renovated (new paint, new floor)

Top Live Aboard
Unfortunately no whale sharks, manta rays and only single reef sharks. Instead, gigantic shoals of fish, so that the sky darkens. In addition, a great crew that was funny and at the same time very attentive and recognized even small things directly and helped. Incredibly good and varied food, greetings to the great cook. Definitely recommended!

Amazing experience
The dive team leader was well organised. Each dive was briefed to ensure a safe and informed dive. Everything from currents, marine life, dive times, drop off and pick up and more helped ensure each dive was as good as it could be. The food cooked by on board chef was excellent. The aft of the boat was organised well and each dive team supported with an experienced dive leader. My wife unfortunately had a medical issue, but the dive leader (Golf) went way above what we expected to make sure nothing was left to chance. We felt very cared for throughout the whole experience. We would highly recommend Sea World 1.

Great economic diving option for the Similan highlights
Economic option for fantastic diving around the Similan's with a safe and professional crew. Rustic boat but everything you need - good food, hot showers, soft drinks, chill out spaces and a good friendly vibe from a experienced boat crew and professional dive crew. Special mention to Audrey the dive cruise director for keeping everyone safe and happy, the rest of the Dive crew Rosie, Jean and Pablo for leading great dives (alongside Audrey of course), the captain and boat crew for getting us bang on top of cool dive sites and picking us up after, and of course the chef for some great food along the way. Beds were a bit hard but overall great value for money.

Amazing food, dives and people
We loved the diving (loads of fish, BIG rays, guitar sharks). Dive master went out of his way to make the best of every dive, especially on days with not all too perfect weather conditions. Crew is really attentive, both under water as on board the ship. We had a good laugh with the boat boys. The chef deserves a special shout out, for her mouth watering dishes were the best we ever had on board!

Nice dive trip with nice people and a great crew
+ Dive guide Beto made his video recordings available afterwards + competent and consistently friendly staff+ very good briefings+ good vibes on the boatA note and not a negative point: You have to be aware that the equipment of the cabins is absolutely basic and you should not expect any comfort. In addition, it is also very loud at night, because either the boat is driving or the power generator is running. For people who are light sleepers, Oropax is absolutely recommended.
