Koh Tao Fun Diving for Certified Divers

On board Nitrox – Free, fresh coffee – Only the best dive spots – 8am Departures

Dive Koh Tao without the stress

On the MV Chaba

Late Departures

No 5am Wake-Ups Required

Forget the early alarms. Our relaxed, late-morning departures right from the beach at 8am give you time to enjoy your morning and still dive the best sites. Ideal for travelers who value both exceptional dives and a vacation pace that doesn’t feel rushed.

Nitrox available on board

The only boat on Koh Tao

Extend your bottom time and reduce fatigue with Nitrox, available on board every trip. We’re one of the few Koh Tao dive boats who can pump EANx on board, giving experienced divers the edge on deeper, longer, and more rewarding dives and the flexibility to choose without committing the day before.

Only the best dive sites

No open water courses on the MV Chaba

Our boat heads to Koh Tao’s top-rated dive locations, including the legendary Chumphon Pinnacle, the dramatic Southwest Pinnacle, and the whale shark haven, Sail Rock. We prioritize epic sites, not easy ones, so you’ll see the most impressive marine life on every dive.

Free, fresh coffee on board

Fuel your dives with delicious coffee

Start your dive day with quality—freshly ground, hot-brewed coffee is always available on board. We believe the little details matter, and this one is a guest favorite. It’s all part of our focus on comfort, quality, and an elevated dive experience.

Give Yourself the Best Chance to See a Whale Shark

No wasted chances at beginner dive sites

Chaba Diving regularly visits Koh Tao’s top deep-water pinnacles—like Chumphon, Southwest, and Sail Rock—where whale shark sightings are most common. By diving the best sites, with fewer divers and Nitrox-fueled bottom time, you maximize your chances of those unforgettable, once-in-a-lifetime encounters with the ocean’s gentle giants.

The Diving

More Reasons To Dive In Luxury

Photographer friendly facilities

Underwater photographers, we’ve got you covered. Our boat is equipped with dedicated rinse tanks, a spacious camera table for setup, multiple charging stations, and a drying air gun—so your gear stays safe, clean, and ready to capture the next breathtaking shot.

Designed for Divers, Built for Comfort

At Chaba Diving, we believe your surface interval should be as enjoyable as your dive. Every feature on our custom-built dive boat is designed to elevate your experience—whether you’re capturing marine magic through your lens or just kicking back between dives.

Relaxation Areas That Feel Like a Resort

From shaded benches to a breezy sun deck and front-row seats at the bow, there’s a perfect spot for every kind of diver downtime. Stretch out for a nap, sip your fresh coffee, or just soak in the sea breeze between epic dives.

Purpose-Built Dive Deck for a Seamless Experience

Built by divers, for divers. Each diver gets a personal tray, wetsuit hanger, and plenty of elbow room. No crowding, no chaos—just smooth, easy access to the water so you can focus on the dive, not the logistics.

Freshwater Showers to Rinse and Refresh

Saltwater doesn’t have to stick around. With four freshwater showers onboard, you can rinse off quickly and feel fresh after every dive—whether you’re gearing up for the next or settling in with a snack.

Luxury Treatment Without the Fuss

You’ll notice the difference in the details: a warm welcome from our professional crew, a fresh towel waiting for you, snacks and fruit between dives, and a delicious Thai lunch included with our 3-dive package. It’s diving done right—with heart, hospitality, and high standards.

Our schedule

We try to keep to our schedule, but we do reserve the right to change it based on safety considerations and weather conditions. We will always endeavour to take you to the coolest spots we possibly can, after all we want to go there too!
