Group tours to the islands from Phuket are designed for the median traveller: they depart at fixed times, stop at crowded spots for fixed durations, and expect everyone to be ready to move on schedule. Families with children rarely fit this mould. Someone needs a nappy change at the wrong moment, a child falls asleep, someone needs lunch earlier than planned, or a toddler refuses to get back in the snorkel mask after five minutes of trying.
A private charter eliminates all of this. You set the departure time (often later works better for families — 8:30am rather than 7am), you stay at a stop as long as the children are enjoying it, you leave when it's time. The crew is there for your family, not managing 20 other paying passengers. For a group of 4–8 people, the per-person price of a private speedboat often works out close to what you'd pay for a premium group tour, and the experience is incomparably better.
Catamarans (twin-hull sailing or power boats) are the best platform for children at sea. The wide beam gives a stable deck — far less rolling than a monohull. There's significant deck space for children to move around safely rather than being crammed onto a narrow speedboat bench. Most catamarans have nets stretched between the two hulls at the bow — children love lying on these above the water while the boat moves.
Catamarans also have enclosed saloon space with shade, seating, and often a small galley. When a child needs to get out of the sun, eat something, or take a nap (it happens), there's somewhere to go. On an open speedboat, there's no shelter and no space to spread out. For any family trip longer than 3 hours, a catamaran is the right choice.
For very young children, proximity and facilities are what matter. Coral Island is 9 km from Chalong — a 20-minute crossing in almost any conditions. The beach has gentle entry, restaurants, toilets, and shade. If something goes wrong you're 20 minutes from Chalong. The crossing is short enough that even a child who dislikes boats will manage. Don't attempt Phi Phi or Racha with children under 3 unless they're very settled at sea.
This age group can handle a 30–45 minute crossing easily in calm high-season conditions. Khai Islands has shallow reef (1–3m) that's ideal for children who are starting to snorkel — they can stand up if they panic, the fish are visible without needing to go deep, and the water is calm. Khai Nok has a beach restaurant for lunch. Coral Island also works well — beach entry, watersports for older children in the group, and restaurants.
Children who can swim confidently are ready for Racha Island. The crossing (45–75 min) is longer but manageable, and the snorkeling at Ao Siam is far more rewarding than Coral Island or Khai — better coral, more fish, clearer water. Children this age will actually see and remember the reef experience at Racha rather than paddling in the shallows. This is also the age where seeing a sea turtle or a small reef shark in the shallows becomes a formative memory.
Teenagers can handle the full Phi Phi experience — the 90-minute crossing, swimming at Pileh Lagoon, snorkeling Viking Beach. If they're interested in snorkeling or diving, Racha is excellent. If they want scenery and Instagram-worthy photos, Phi Phi is the destination. Phang Nga Bay also works well for teenagers interested in photography or history — the James Bond Island connection resonates.
Phuket's peak family travel periods align with UK, European, Australian, and Chinese school holidays. The Christmas–New Year period (Dec 22–Jan 6) and the February half-term window are the busiest, and good private charters book 4–6 weeks in advance during these periods. If you're travelling in these windows, don't leave the booking to the week before arrival — the boats you want (stable catamarans with shade and proper facilities) fill up first.
Easter and the Australian school holidays in July are also busy. The best boats and most flexible operators get reserved first; what's left last-minute is often older speedboats with less family-appropriate equipment.
Depart Chalong 8:30am on a catamaran. Khai Nai snorkel (morning, calm, shallow). Transit to Coral Island. Lunch on Long Beach. Afternoon beach play and watersports for older children. Return to Chalong 4pm. Transit time kept under 45 min each way.

There's no firm minimum, but practically speaking, infants under 6 months are uncomfortable at sea — the sun exposure, rocking motion, and limited facilities make it hard to manage. From 6 months to 2 years, short trips to Coral Island on a calm catamaran are manageable if the parents are prepared. The key is proximity: Coral Island (20 min) is the right target for very young children, not Phi Phi (90 min).
No — non-swimmers can join any charter and enjoy the boat, beach, and scenery without entering deep water. Life jackets and shallow wading areas are available at every destination near Phuket. Non-swimming children can snorkel safely in a life jacket in very shallow water. The charter isn't cancelled because one person doesn't swim; it just means they enjoy the boat and beach rather than the reef.
Seasickness tablets (children's formula — check age suitability on the packaging) are very effective if given 30–45 minutes before boarding. The most susceptible age group is 5–12 years old. Keeping children looking at the horizon rather than down at the boat, keeping them out of enclosed spaces, and having them eat something light before the trip all help. If a child does get sick, most recoveries happen quickly once you anchor at the destination. On a private charter, you can also ask to slow down if conditions are rough.
Yes, with the right conditions and equipment. The key is a proper-fitting mask — if a child's mask leaks constantly, the experience is miserable. Khai Islands and Coral Island have water shallow enough that children who panic can stand up, which makes first-time snorkeling much less stressful. Start children in knee-deep water to get used to breathing through the snorkel before moving to deeper areas. Children aged 6+ can usually manage this without much difficulty; 4–5 year olds vary significantly.
Speedboats typically take 6–12 guests comfortably (check certified capacity, not maximum). Power catamarans take 10–20 guests and provide much more space for a family. Sailing catamarans carry 6–12 guests with more comfort and shade. For a family of 4–6 with children, a speedboat is economical; for 6+ or if children's comfort is the priority, a catamaran is worth the extra cost. Children count as guests for capacity purposes.
