Koh Rock & Koh Haa (8 hrs)
Most people don't realize the Andaman Sea has a monsoon season that actually makes Thailand better, not worse. Those brief tropical showers? They clear out the casual tourists and leave you with the real deal—authentic Thailand without the crowds choking up Instagram spots.
The Apollo, a nimble 47ft private speedboat, cuts through these waters like it owns them. Which, honestly, it kind of does after years of island-hopping runs. What makes this boat pretty cool for Thailand is the speed—you're not slogging along on some lumbering catamaran. You hit Koh Rok Islands (Rok Nok & Rok Nai) in eight hours flat, leaving more daylight for actually doing stuff instead of just sitting on deck pretending to relax.
Here's what works well in these waters: Koh Rok's granite cliffs, pristine snorkeling zones with visibility that'll mess with your depth perception, and fish populations that make you wonder if you've accidentally swum into an aquarium. The hardest choice here is island A or island B (spoiler: both are epic). Thailand has a way of surprising you with sea turtles casually swimming past, coral gardens that haven't been hammered by mass tourism, and anchorages so sheltered you'll sleep like you've never slept before.
Fair warning though—tropical showers make speedboat rides bumpy. Bring a waterproof bag for your phone. November through February runs smoother, but monsoon season (May-October) offers that authentic local vibe with refreshing breaks from the heat.
Perfect choice for your Thailand yacht charter.
