Racha Yai (8 hrs)
Thailand has a way of surprising you with its sheer number of pristine islands, and honestly, trying to hit them all in one day is absolutely doable—if you've got the right boat. The Apollo, a custom-built private speedboat, cuts through these waters like it was born here (which, practically speaking, it was). At 47 feet, she's nimble enough to slip into hidden lagoons that the slower tour boats miss entirely, yet comfortable enough for up to 30 guests who actually want to enjoy themselves instead of just surviving the journey.
Your target: Koh Racha Yai (Koh Raya Yai). This island sits about 25 kilometers south of Phuket and rewards early departures with uncrowded snorkeling spots and crystal waters that make Instagram captions write themselves. The real magic happens when you beat the midday crowds—you'll have sections of beach feeling almost private. Bring reef-safe sunscreen because these waters are home to genuinely healthy coral, and you'll want to look after them (and your skin).
November through February offers that sweet spot of calm seas and clear skies. But here's the thing: monsoon season gets unfairly bad press. Those brief tropical showers? They're warm, refreshing, and keep the tourist hordes inland sipping coffee in Phuket Town. You get more authentic Thailand this way.
The Apollo absolutely crushes full-day island runs. Multiple stops, minimal transit time, maximum exploration. This speedboat setup is your shortcut to island-hopping bliss without the exhaustion factor.
