Khai Islands (8hrs)
Most tourists never realize the Khai Islands are actually three separate gems, each with distinct personalities just 15 minutes from Phuket's chaos. The hardest choice here is Khai Nai's pristine beaches or Khai Nok's snorkeling paradise (spoiler: both are epic).
What matters in Thai waters is having a crew who knows which hidden coves offer the best coral viewing when day-trippers crowd the main beaches. Mary, this Azimut 60ft beauty, comes with exactly that advantage. Her professional Thai crew navigates to secret snorkeling spots while you're still deciding between the poolside bar or sun deck.
It is recommended to bring underwater cameras because these waters showcase some of Thailand's clearest visibility. The cool season November through February delivers perfect conditions, though honestly, tropical showers during monsoon months create their own magic. Brief warm rain adds authenticity to your Thailand adventure.
Makes sense for Thailand logistics: eight hours gives you proper island-hopping time without the rushed ferry schedule nightmare. Mary's spacious layout accommodates up to 12 guests comfortably, meaning your group can spread out across multiple decks while the crew handles navigation between islands.
And here is the best part about Thailand: while other boats circle the same tourist spots, your crew knows exactly when to move for optimal snorkeling conditions and beach lounging. Your shortcut to island-hopping bliss.
