Snorkel time can be this simple. I love the smooth private group pace and the fact that snorkel gear is ready for you before you even hit the water. The only real drawback is that lunch isn’t included, so plan to handle meals on your own during the stops.

What makes this cruise feel easy is that the boring parts are handled: you get round-trip transfers from Phuket and the admission fees are taken care of. That means less stopping to pay, fewer steps to manage, and more time relaxing with your own group.

Key highlights

• Private speedboat, your schedule: Your group sets the rhythm, with time built in for beach breaks and snorkeling.
• Gear provided for snorkeling: Snorkeling equipment and life jackets are included, so you don’t need to pack extra bulky stuff.
• Admission fees handled: You won’t be scrambling for island entry tickets on the spot.
• A family-friendly first snorkel spot: Koh Khai Nai is shallow and clear, which is ideal if you’re traveling with kids.
• Mai Thon Island’s “Honeymoon” reputation: Crystal-clear waters plus a known pod of dolphins gives the day a wow factor.
• Snacks + drinks for the water portion: Bottled water, soda/pop, and snacks are included—just treat lunch as separate.

A Private Speedboat Day Around Khai and Mai Thon

This is a classic Phuket island day, but run with a private-speedboat feel. You’re not joining a large group and hoping you end up in the right spot at the right time. Instead, you’ll move from island to island with your own group, using the schedule like a guide while still having room to go at your own pace.

The vibe is relaxed: snorkel when you want, swim if the conditions are good, then return to the boat and cool down. You’ll also get a clear structure to the day, with built-in stretches for checking in, beach time, and the second snorkel stop.

Price and Value: What You’re Really Paying For

The price is $807.98 per group (up to 15 people). That can feel steep at first glance—until you do the math the way you actually travel.

• If you fill the group (15 people), it’s about $54 per person.
• If you’re a smaller party, the per-person cost rises, but you’re still buying something solid: private transportation + snorkeling gear + snacks + included admission fees.

Here’s the practical value angle. You’re paying for fewer hassles:

• Transfers are part of the package.
• Entry fees are handled.
• Snorkeling equipment is provided.
• You’re not bringing extra gear, and you’re not paying on the spot for every island.

If your group has enough people to make the boat “full,” the deal gets a lot more comfortable. If you’re traveling as a couple or small group, it’s still a good value if you care about privacy and pace more than spending the day “budget-style.”

Getting Started at 5 Star Marine: Briefing and Break Before the Boat

Your day begins at 5 Star Marine. You’ll check in at their offices, get a full tour briefing, and have a coffee, tea, or cool drink while things get organized. This matters more than it sounds. When you understand where you’re going and roughly how long you’ll be at each stop, you can relax instead of burning energy on guesswork.

There’s also time to store luggage you don’t need. That’s a small detail that makes a big difference once you’re on and off the boat. Less clutter equals fewer “where did I put it” moments.

The briefing portion is about 30 minutes, and admission is included for that start segment.

Stop-by-Stop: From Koh Khai Nai to Khai Nok and Back Again

This itinerary is built around two things: great snorkeling options and a smooth rhythm of beach time.

Koh Khai Nai (First Stop): Shallow Water and Easy Snorkeling

You’ll head to Koh Khai Nai for about 1 hour 30 minutes. This spot is known for clear, shallow water, and it’s specifically described as perfect for families with young children. That’s useful if your group includes people who want to try snorkeling without feeling overwhelmed.

Expect tropical fish and an easy water entry right off the snorkel area. The length of the stop gives you time to get comfortable—first try, swim around, then decide if you want to go again.

Admission is included here, so you don’t need to handle that on your own.

Khai Nok Island (Stop 3): Beach Relaxation + Time to Eat

Next up is Khai Nok Island for around 1 hour. This is the “slow down” break. You’ll have time for the white sandy beach, plus a window for lunch and drinks during the stop.

One important note: lunch is listed as not included overall. So treat this as your chance to grab a meal on your own while you’re there, not something the tour guarantees.

You also get time for fresh coconut, which fits the easy island-day style—cool, simple, and refreshing after time in the sun.

Admission is included for this stop.

Koh Khai Nai (Second Stop): Another Snorkel Chance Off the Boat

Then you return to Koh Khai Nai again for about 1 hour 30 minutes. This second visit shifts the focus to snorkeling right off the boat, with a variety of coral and marine life you can explore.

Why a second snorkel stop is smart: it gives you two bites at the apple. If the first water time feels too short (or if you want to focus on marine life after your bearings are set), this helps you get a fuller experience.

Admission is marked as free for this second Koh Khai Nai segment, which again keeps you from thinking about payments mid-day.

Mai Thon Island: Clear Water Time and That Dolphin Reputation

Ko Mai Thon Island is where the day leans into the “wow” factor. You get about 45 minutes, and it’s known as Honeymoon Island for crystal-clear waters.

It’s also described as having a pod of dolphins, and the island is associated with a Find Nemo vibe off the beach. Even if you’re not chasing a specific “see it on cue” moment, this stop is still about the water clarity and the classic island-photo setting.

Forty-five minutes is not long enough to do everything slowly, but it is enough to:

• get in the water,
• find a calm spot to float and watch,
• and enjoy the shoreline before heading to the next beach moment.

Admission is included here.

Ko Rang Yai: Beach Hangout, Fruit Refreshments, and a Sunset Option

The final island segment is Ko Rang Yai, with about 45 minutes. This stop is more about relaxation than snorkeling. You’ll have time on the sandy beach, plus fresh fruit and cool refreshments.

There’s also a note about watching the sunset if you want. Not every island-day includes an easy “end on a nice moment” option, and this one gives you the choice without dragging you into a long extra activity.

After that, you’ll take a short cruise back to the pier. It’s the kind of wrap-up that keeps you from feeling rushed, even if your day started early.

Snorkeling Setup That Actually Helps: Gear, Life Jackets, and Pace

The tour includes snorkeling equipment and life jackets. That means you can travel lighter. No need to hunt down a rental place, no worrying about “does this fit?” at the dock.

It also changes how you plan your day. When gear is handled, you can spend more energy on enjoying the water rather than logistics. Your best move is to arrive feeling ready to swim, then use the first snorkel window (Koh Khai Nai) to get comfortable before you spend more time hunting coral and marine life.

A private tour also helps with pace. If someone in your group wants to go slower, you’re not stuck behind a pace-setter. The itinerary gives you structured time, but you’re not forced into a group sprint.

Food and Comfort: Snacks Are Included, Lunch Is Your Own Call

Here’s the honest food setup:

• Included: snacks, bottled water, and soda/pop.
• Not included: lunch.

So you’ll be drinking and snacking throughout the water portion, which keeps energy up and helps prevent the mid-day crash. Then, when you reach the Khai Nok stop (where lunch time is built into the schedule), you’ll need to buy your own meal or handle it however you prefer.

If your group dislikes paying for meals on trips, plan for simple backups: snacks from home and a “we’ll get something easy at the island stop” attitude. The good part is you’re not stuck hungry while the boat is moving, because snacks and drinks are included.

On top of that, transfers are handled with an air-conditioned vehicle, which is a relief in Phuket’s heat.

Who This Private Cruise Is Best For (and Who Might Prefer Something Else)

This cruise fits best if you want a few specific things:

• Your group wants privacy and control. Private transportation and only your group on board means less waiting and less negotiating where to stand, swim, or take photos.
• You care about snorkeling with minimal hassle. Gear is provided, and the itinerary includes two Koh Khai Nai segments (one shallow and family-friendly, one focused on snorkeling off the boat).
• You like island variety in one day. You get beaches, snorkeling time, and a second beach-focused stop at Ko Rang Yai.

This might feel less ideal if your main goal is a long, unbroken beach day with time to roam. The total structure is island-hopping with multiple stops, and each stop is time-limited. If you want hours and hours on one beach, you may prefer a different style of tour.

Should You Book This Khai and Mai Thon Private Cruise?

Book it if:

• you’re traveling with a group large enough to make the per-person price feel fair,
• you want snorkeling gear and admission handled so you can focus on the experience,
• and you care about a calmer, more controlled day on the water.

I’d think twice if:

• you don’t want to manage lunch yourself (since lunch isn’t included),
• or your group wants a slow itinerary with very long beach time at one location.

My bottom line: this is a well-structured private island cruise for people who value fewer hassles and smoother pacing. If you line up your group size and show up ready for snorkeling, you’re set up for a day that feels easy from start to finish—especially with a crew that clearly runs the day with friendly energy (one 5-star review called out the crew as friendly and made it sound like a true memory-maker, and the operator’s response was signed off by Shaun).
