The Sawanu catamaran cuts clean lines through the Andaman Sea as limestone boulders of the Similan archipelago reappear on the horizon — white beaches glinting, reefs simmering beneath clear water. Onboard, a light breakfast and briefing set the pace; by mid-morning you’re anchored off Island No.9 with fins on and a reef full of curious fish circling the boat.

Book early-season mornings
Departures before 8:00 AM often have calmer seas and better underwater visibility for snorkeling.
Use reef-safe sunscreen
Apply biodegradable sunscreen before boarding to protect coral and avoid greasy lens fogging for masks.
Secure loose items
Strong winds and open decks mean hats and phones should be stowed or tethered during transit.
Practice shallow-water buoyancy
Avoid standing on coral by practicing neutral buoyancy and entering reefs feet-first from the surface.
Reef-safe sunscreen
