Minimum age to dive (and to come on board)
PADI / SSI Junior Open Water — minimum age 10. Maximum depth 12m, must dive with a parent or pro. PADI / SSI Junior Advanced Open Water — minimum age 12. Maximum depth 21m. PADI / SSI Open Water — minimum age 15. Bubblemaker / Seal Team — pool / shallow programmes, age 8+. Most liveaboards accept divers from age 12 (Junior AOW) on standard recreational dive routes, and age 10 with strict parent supervision and shallow profiles. For non-divers, many operators accept kids from age 6+ as snorkelling / surface guests if cabins are available — but always confirm with the operator.
Family-friendly liveaboard regions
Maldives — calm seas, warm shallow water, easy diving, lots of snorkelling, family-favourite destination. Many boats explicitly welcome kids 12+. Egypt (northern Red Sea) — short flight from Europe, calm wrecks, gentle reef dives. The Brothers / Daedalus / southern Red Sea is too challenging for junior divers. Indonesia — Komodo and Bali for older kids 14+, currents are too strong for younger juniors. Caribbean (Bahamas, Belize, Cayman) — perfect for first family trip, calm water, English-speaking crews. Avoid for kids: Galapagos, Cocos, Socorro (cold, current, advanced), Sudan (logistics).
Cabin and boat layout choices
Look for: triple or quad cabins (most boats have a few), connecting cabins (luxury boats only), large indoor lounge for downtime when not diving, snorkel programmes for non-divers and siblings. Avoid: boats with only twin / double cabins, very small boats (10–14 guests, no escape from the group), boats that don't have a snorkel guide as well as a dive guide. The best family liveaboards explicitly market family cabins and family rates — that's your filter.
Pricing and discounts for children
Most operators offer 20–50% discount for kids under 12 sharing a parents' cabin (snorkellers / non-divers). Some give 10–20% for junior divers up to 16. Diving fees are usually identical to adults from age 12 upwards. Always ask the operator about: family discount, junior diver supplement, snorkeller rate (cheaper than diver), kids-eat-free policies (rare but exist), free junior diver instructor for the first 2–3 dives. Smaller boutique operators are often more flexible than the big chains.
Practical tips for family trips
Bring entertainment for non-dive time: surface intervals are an hour each, that's 4 hours a day of "what do I do now" for kids. Tablets with downloaded movies, books, card games. Dive briefings can be long — kids get bored. Negotiate with the dive guide for kid-friendly briefings. Bring kid-size dive gear (mask, fins, wetsuit) — adult rental rarely fits and a poorly fitting mask is the #1 reason kids drop out of diving. Choose a route with shorter transfers and shallower dives for the first family trip — Komodo's currents and 30m walls are not where you start. And: brief your kids on boat etiquette before the trip — tipping, dive deck rules, quiet hours.
