Phuket: SCUBA Diving Day Trip King Cruiser, Shark Point, KDM

The King Cruiser wreck is the main draw here: a sunken passenger ferry that gives experienced scuba divers a serious underwater site, followed by Shark Point and Koh Doc Mai. You can reach depths of 30 meters, so this is not a casual introduction to scuba.

I like the practical package: hotel pickup, three tank dives, breakfast, lunch, snacks, drinks, an instructor, and travel insurance are included. I also like the mix of sites, since you get a wreck, a marine-life site, and a rocky island setting in one long day.

The catch is simple: this trip is for advanced divers only. You need at least 20 dives and SSI Advanced Adventurer or equivalent certification. Equipment, a dive computer, and Nitrox cost extra, and anyone prone to seasickness should think carefully before booking.

Five things to know before you book

• King Cruiser is the headline site: You descend to a wreck and explore its underwater structure and marine life.
• Three sites make this more than a single-wreck outing: The route includes King Cruiser, Shark Point, and Koh Doc Mai.
• Advanced certification is required: You need at least 20 dives and SSI Advanced Adventurer or equivalent training.
• The basic price covers a full day: At $176 per person, you get up to three dives, transfers from selected Phuket areas, meals, drinks, tanks, weights, and an instructor.
• Plan for extra cash: Scuba equipment costs 500 THB, a dive computer costs 300 THB, and Nitrox costs 300 THB per tank if ordered in advance.

Why this Phuket scuba day is aimed at serious divers

This is a long, demanding day rather than a relaxed boat trip with a quick swim. The schedule lasts 12 hours and includes up to three underwater sessions, so you need enough experience to handle changing conditions, repeated descents, and a potentially tiring day at sea.

Aum Scuba sets the minimum at 20 logged dives and requires SSI Advanced Adventurer or an equivalent qualification. You must bring your diving certification and dive log. That requirement matters because the route can reach 30 meters, well beyond the depth normally associated with a first-time or beginner scuba session.

I appreciate the clear cutoff. It keeps the trip focused on people who already know how to control their buoyancy, monitor air use, and respond to ordinary problems underwater. If you are still building basic confidence, this is the wrong trip. Phuket offers other options for beginners, but this one is designed around experienced certified divers.

The instructors speak English and Thai, and you travel with an SSI or PADI-qualified instructor. The specific guide assigned to your boat is not given in the available details, so do not book expecting a named instructor. What is clear is that professional instruction and supervision are part of the price.

Pickup, breakfast, and the long day at sea

Free hotel pickup and drop-off are included from Patong, Karon, Kata, Chalong, Rawai, and Naiharn. You should wait at your hotel reception five minutes before the scheduled pickup and confirm with the driver that your name is on the list.

If you stay outside those areas, a transfer can be arranged for an extra charge depending on the location. Check this before you pay, since an apparently convenient package can cost more once transport is added.

The 12-hour duration includes the day’s travel, surface intervals, meals, and three underwater sessions. Exact pickup and return times depend on the date, so check availability for the start time and allow the whole day. This is not an activity to squeeze between a morning flight and an evening dinner reservation.

Breakfast is included, along with lunch and afternoon snacks. Tea, coffee, water, and soft drinks are also provided. Beer is available to buy for 60 THB per can, in cash, but alcohol is not included. I would save it for after the trip, since staying hydrated and alert matters more than having a drink on the boat.

The King Cruiser wreck: the day’s main attraction

King Cruiser is the site that gives this trip its identity. You descend to a wreck and inspect its underwater form while looking for marine life around it. The maximum stated depth is 30 meters, so you need advanced-level training and careful air and time management.

A wreck can feel very different from a standard reef. Instead of following only a natural rock formation, you have a large man-made structure to orient yourself around. That makes the site interesting for divers who enjoy visual exploration, but it also demands discipline. You should follow the instructor’s direction, avoid touching the wreck or marine life, and keep a close eye on your gauges.

The description does not promise penetration inside the wreck, and you should not assume that going inside is part of the trip. Your actual route depends on the guide, conditions, and safe diving practice. The clear promise is exploration around the King Cruiser wreck and its marine life.

This is also where certification and experience have practical value. At 30 meters, gas consumption can rise compared with a shallow outing, and the depth adds more responsibility to every decision. I would treat the wreck as the centerpiece, not as a place to push your limits.

Shark Point and Koh Doc Mai complete the trio

Shark Point gives the day a second kind of underwater setting. Its name may catch your attention, but the supplied details do not guarantee shark sightings. Book it for the site itself and the chance to see marine life, not for a promised animal encounter.

That distinction is important. Underwater wildlife is never a vending machine, and the operator only specifically promises marine life exploration. You may find the site more appealing if you enjoy looking carefully and accepting that nature decides what appears.

Koh Doc Mai, also known as KDM, rounds out the three-site plan. The information identifies it as one of Phuket’s three featured scuba sites but does not provide a species list or a detailed route. I would expect it to offer a different underwater backdrop from the wreck, but I would not book based on a particular creature or formation that has not been promised.

The value of the three-site format is variety. King Cruiser gives you a wreck, Shark Point gives you another marine-life setting, and Koh Doc Mai adds a third location. You are not spending the whole day repeating one view. At the same time, three sites mean a busy schedule, so surface intervals and boat transfers are part of the experience rather than wasted time.

What is included, and what you still pay for

The advertised price is $176 per person. That is a fair package for a full 12-hour certified scuba outing if you need transfers and meals, but it is not the final cost for every diver.

Included in the base price are:

• Up to three dives
• Tanks, weights, and weight belts
• An SSI or PADI-qualified instructor
• Hotel pickup and return in the listed Phuket areas
• Breakfast, lunch, snacks, water, tea, coffee, and soft drinks
• Travel insurance

Scuba equipment rental is not included. If you need the operator’s equipment, add 500 THB per person, payable in cash on the day. A dive computer costs another 300 THB per person, also payable in cash.

Nitrox is available for qualified divers at 300 THB per tank. You must order it in advance, and it is recommended for longer bottom time. The extra cost may make sense for a diver who is properly qualified and wants to use Nitrox within their training and planned limits, but you should not treat it as a way to ignore depth, time, or decompression rules.

Underwater photos are also excluded. If taking pictures is important to you, ask about availability before booking, since the package does not promise a photographer or images.

The price becomes easier to justify if you use the included transfer, food, tanks, and instruction. It is less attractive if you already have transport, your own gear, and no need for the meal package. Add the extras honestly before comparing this trip with another operator.

Meals and onboard comfort

Food is a useful part of this package because the day is long. You receive breakfast before or around the start of the outing, lunch during the day, and afternoon snacks. Tea, coffee, water, and soft drinks are included, which means you do not need to plan every snack yourself.

The available information does not specify the menu, boat layout, cabin facilities, or group size. I would not assume a luxury vessel or a quiet private charter. Think of the food as practical fuel for a full day at sea, not a culinary event.

Bring only what you need and protect personal items from water. You should also plan for the ordinary reality of a long boat day: early pickup, changing clothes, repeated time in and out of the water, and the possibility of fatigue after the third session.

Seasickness is a serious consideration. The trip is specifically not suitable for people prone to seasickness. If that describes you, three site transfers and a 12-hour day may make this a poor match, even if the underwater route looks appealing.

Safety rules that matter after the boat returns

You must leave at least 18 hours between your final scuba session and flying. Build that buffer into your Phuket plans before booking flights. A last-day underwater trip followed by a next-morning departure does not fit the stated guidance.

The operator also excludes non-swimmers, uncertified divers, people with low fitness, children under 15, people over 70, and people with certain medical concerns. Specifically listed conditions include pre-existing medical conditions and high blood pressure.

These restrictions are not minor fine print. Three underwater sessions and a long day at sea require physical readiness. If you have a medical concern, get appropriate professional advice before booking and disclose relevant information to the operator.

Do not touch marine life. That rule protects the animals and helps you avoid damaging the underwater environment. Keep your hands off the wreck and reef life, maintain buoyancy, and listen to the instructor’s directions.

The trip includes travel insurance, but you should still check what that insurance covers. The supplied details do not list its limits, exclusions, or claims procedure.

Who will get the most from this trip

I would choose this outing if you already hold the required certification, have at least 20 dives in your log, and want three substantial sites in one day. It suits divers who prefer an active schedule and who are especially interested in wrecks and marine life.

It is also a sensible choice if you are staying in Patong, Karon, Kata, Chalong, Rawai, or Naiharn. Included transport removes one chore, and the meals and drinks make the $176 price easier to understand.

I would hesitate if you are newly certified, out of practice, nervous about depth, or hoping for a gentle introduction. I would also look elsewhere if you need a guaranteed wildlife encounter, a private boat, included equipment, or a specific underwater photographer.

The trip can work well for an experienced diver traveling with a non-diving companion only if that companion has another plan. The supplied details describe a certified scuba program, not a sightseeing or snorkel option.

Booking details that can save you trouble

You can cancel up to 24 hours before the activity for a full refund, and you can reserve now and pay later. That flexibility helps if your Phuket schedule is still changing, but it does not remove the need to check your certification and flight plans first.

Have your certification and dive log ready. Confirm your pickup location, ask about any extra transfer cost, and bring cash for equipment, a dive computer, Nitrox, or beer if you plan to buy any.

I would also confirm whether you need to rent equipment before the day. The available terms say equipment hire is payable in cash, while Nitrox must be requested in advance. A little planning prevents an avoidable scramble at the dock.

Should you book the King Cruiser, Shark Point, and KDM trip?

Book it if you are an experienced, certified scuba diver who wants a full day built around three Phuket sites, with the King Cruiser wreck as the main prize. The combination of a wreck, marine-life sites, meals, transfers, tanks, and professional instruction gives the $176 price real value, especially if you need rental transport and food.

Skip it if you are a beginner, dislike long boat days, suffer from seasickness, or need all equipment included. Before committing, add the 500 THB equipment fee, 300 THB computer fee, and any Nitrox cost to the advertised price. If those terms work for you and you can protect the required 18-hour no-fly window, this is a focused, demanding day for seeing more than one of Phuket’s best-known underwater sites.
