A yacht charter week with one or two children under six runs the same base rate as any charter week (€180,000 to €700,000 for a 40m to 60m motor yacht in peak Mediterranean season, as of May 2026), with €2,000 to €5,000 of additional cost for nanny, kid-specific provisioning, and safety kit. The real cost is not money. It is itinerary. The week is governed by an eight-hour daily routine (wake, breakfast, nap, lunch, nap, swim, dinner, bed) and that routine eats the cruising days you might otherwise plan around adult rhythms.
This post is for the parent (one or both) who has decided the family week will be on a yacht and wants the operating manual: which destinations work, which yachts work, what the crew can and cannot do, the safety kit that needs to be on the yacht before you board, and the specific things first-time-family-charter clients always get wrong.
Why under-6 is its own category
Children between six and twelve adapt to a yacht week quickly. They sleep through engine noise, they tolerate boat motion, they entertain themselves with snorkels, toys, and water. They follow simple safety rules. They eat the family menu.
Children under six do not. A two-year-old wakes at 6.30am regardless of the engine. A four-year-old gets seasick more readily than older siblings. A five-year-old cannot be left unattended on a swim platform. A nine-month-old needs the same nap window, the same bottle temperature, and the same bedroom darkness aboard a yacht in Hvar as in Hampstead. The yacht has to fit the routine, not the reverse.
The yachts and crews that have done this often (and there is a discrete subset of charter yachts that specialise in family weeks) understand it. The yachts that have not, or whose crew is more accustomed to corporate hosting and twelve-adult parties, do not.
The eight-hour day that governs the week
Plan the day around the kids, not the cruise. The typical under-6 day on a charter week:
06.30 to 08.30. Kids wake. Parents and one crew member (chief stew or nanny) handle breakfast on the aft deck. Yacht is at anchor in a quiet bay. Engines off.
08.30 to 10.00. Beach time at anchor. Calm-water swim, sand if there is a beach the tender can reach. Adults swim with kids. Older kids on the seabob or paddleboard.
10.00 to 12.00. Nap window (younger ones). Yacht repositions during this window, ideally to the lunch anchorage 12-20 nautical miles away. Engine noise wakes some kids and not others. The captain runs at low cruise speed (10-12 knots) to keep noise and vibration down.
12.00 to 13.30. Arrive at lunch anchorage. Lunch on the aft deck, served by the chef. Family meal, kids eat early.
13.30 to 15.30. Afternoon nap (both ages). Adults read on the foredeck, swim from the platform. Yacht stays anchored.
15.30 to 18.00. Afternoon swim, water sports for older kids, beach club visit by tender if there is one nearby. The kids' main activity window.
18.00 to 19.30. Kid dinner aboard, bath aboard, bedtime aboard. Chief stew or nanny helps with the bath.
19.30 to 22.30. Adult dinner. Either aboard (chef plates an actual dinner, two adults dine on the upper deck while kids sleep below) or ashore (parents tender ashore, nanny aboard with the kids). The yacht stays at anchor.
22.30 onwards. Adults sleep when they sleep. Kids wake the household at 6.30am the next morning.
This is the realistic week. Trying to run a yacht week on adult time with kids under six aboard ends in tears (usually the kids', occasionally the parents'). The captain has done this routine before and will offer it. Accept it.
Destinations that work for under-6
Croatia (Split, Hvar, Korčula). The best Mediterranean answer for very young children. Short hops (15-30 nautical miles between anchorages), very calm water (the Dalmatian coast is a series of protected bays), good ashore options for a stroller-and-ice-cream break. The Croatian charter season is May to October. The water is warm by late June. We have placed dozens of families with under-6s here and the feedback is consistent. See the Croatia charter page for the destination-side notes.
The Saronic Gulf (Hydra, Spetses, Poros). The Athens-base alternative. Short hops, calm water, ashore towns that handle kids well. Hydra has no cars (excellent for under-3 stroller use). 12% Greek VAT. Slightly busier than Croatia but easier flights.
The Balearics (Mallorca, Menorca). Mallorca's calm-water bays (Pollensa, Soller, the south coast bays) work well. Avoid the Ibiza scene side with under-6s, the music and the late-night activity ashore is not the right environment. Menorca is the under-6 sweet spot of the Balearics. Calmer than Mallorca, fewer crowds.
The BVI (Tortola, Virgin Gorda). The Caribbean answer for under-6s. Short hops, very calm water, easy beach landings, no real waves. Charter season December to April. The downside is the long flight to BVI for very young children.
Sardinia (Costa Smeralda, La Maddalena). Strong for under-6s if the week is calm. La Maddalena archipelago is the highlight: short hops, beach anchorages, very calm. The mainland Costa Smeralda is busier and louder.
Turkey (Bodrum and the Gulf of Gokova). Strong under-6 destination. Calm water, short hops, traditional gulet-style yachts work well for very young children (low to the water, easy swim access). Hot in August.
Destinations to avoid with under-6s:
The Cyclades. Meltemi winds (15-30 knots routinely) make for choppy passages and uncomfortable anchorages. Mykonos and Santorini are loud at night. The crossings between islands are tiring for young children. Save the Cyclades for kids aged 8+.
The Amalfi Coast. Swell at most anchorages, hard tender landings at the Positano and Amalfi quays, narrow steep streets ashore that are stroller-impossible. The yacht week works for couples and older families. Under-6 families end the week tired.
Anywhere requiring a passage over 30 nautical miles in one hop. A four-hour passage with a two-year-old is a long four hours, regardless of the yacht. Plan in 15-25 nautical mile legs.
The Aeolian Islands or Pontine Islands in August. Beautiful, but the anchorages roll. Under-6 kids do not enjoy a rolly night at anchor. Save for September shoulder.
The yachts that work for under-6
The category of charter yacht that is described as "family-friendly" is real but not always what the broker means. The yacht traits that actually help with under-6:
A real beach club with a flat opening transom. The kid steps into the water from a stable platform two feet above the surface, not a steep ladder. This is the single most important feature for under-5s. Sanlorenzo SD132 has it. Benetti Retreat has it. Heesen FDHF series has it. Many older 50m yachts do not.
Cabin layouts with adjoining staterooms. Most family charter yachts have a master plus a "VIP" plus two "guest" cabins. Adjoining doors between guest cabins allow the kids to sleep in one with the parents in the adjoining one. The yachts with this layout: Sanlorenzo SD126, Benetti 50M, Heesen 50m, some Sunseeker 131s.
A separate kid bathroom. Two guest cabins sharing a "Jack and Jill" bathroom is the norm. A separate child-friendly bathroom (no glass shower door, a real tub or a child step) is rare and the captain will know if his yacht has one.
A galley that can prepare child food. Chef makes pasta with butter, a real chicken cutlet, basic puréed vegetables for an under-2. Some chefs are excellent at this. Some are not. Ask the broker for the chef's CV.
A captain who has done family weeks. The captain who has run his yacht for four family weeks in the last two seasons handles the routine. The captain who is more accustomed to corporate hosting will be polite but slower to adapt.
The yachts we would pass on for an under-6 family:
Open sportscruisers (Mangusta, Pershing, Riva 110). Open transom, ladder-style swim access, less interior shade, louder at anchor (engines run more for AC). Wrong for under-6.
Most sailing yachts. Heeling, fewer protected indoor areas, harder galley work in any breeze. Day-charter sailing yachts work. A week aboard a sailing yacht with a two-year-old is harder than it needs to be.
Yachts without proper railing on the foredeck. Some 30m to 40m yachts have a low or partial foredeck rail. With an under-3 aboard, this is a problem. Check the photographs.
Yachts with hot tubs accessible from open deck without a child gate. Real safety concern. The chief stewardess will lock it, but the parent has to want to check.
The nanny question
The single most important decision after yacht selection is whether to bring a dedicated nanny.
Options:
Bring your own family nanny. Cost: nanny's normal rate (€150 to €350 per day in most U.S. and U.K. markets), plus airfare, plus accommodation (an additional crew bunk on the yacht, sometimes a hotel ashore on long port nights). Most yachts can fit one additional non-charter-guest staff member in the lower deck crew cabins; some cannot. Confirm before booking. Total weekly cost: €2,500 to €5,000 plus board.
Hire a nanny from a charter-nanny service. Cost: €1,800 to €3,200 per week for the nanny's wage, plus board (€200 to €400). The nanny boards the yacht, sleeps in a crew bunk, works dawn-to-bedtime, has one half-day off. Pre-vetted with the yacht broker. The major Mediterranean charter agencies all have a nanny roster.
Use the yacht's existing stewardess as part-time nanny. Some family-friendly yachts have a stewardess who has been trained as a nanny and is happy to play that role. Cost: included in the charter rate or APA. Limited to part-time (the stew also has stew duties).
No nanny. Both parents handle the children for the full week. Possible. Hard work. The chief stew helps when she can. The week is shorter on adult relaxation. For one child over four, this works. For two kids both under five, the nanny is worth every euro.
Our default recommendation: dedicated nanny for any week with one or more under-3 child, or two or more under-5 children. The €3,000 is the best money you spend on the trip.
The safety kit and the medical question
Confirm in writing with the broker that the yacht has, aboard, before you embark:
- Lifejackets sized for each child (a 12kg child lifejacket is not the same as an adult small)
- Stairgates if the children are under 3 (the chief stewardess installs at embarkation)
- A child-locked medicine cabinet
- A child first aid kit (separate from the main yacht first aid kit)
- A high-chair or booster for meals (high-end yachts have one; not all)
- A travel cot or crib for nap-time and overnight (high-end yachts have one; not all)
- Sun-protection swimwear in child sizes (some yachts stock; most do not, bring your own)
The medical question: every charter yacht has a captain who is medically trained to MCA standard, has a satellite phone to a 24-hour medical service (typically MedAire or equivalent), and can run a medevac plan. The distance from the anchorage to the nearest hospital varies hugely. The Croatian coast is within 30 minutes of a hospital almost everywhere. The Saronic Gulf is within 60 minutes. The remote BVI anchorages can be 90 minutes. A long passage to Pantelleria or Lampedusa can be three hours from a real medical facility.
For a child with any underlying medical condition, brief the captain in writing four weeks out. Include medication regimen, allergy profile, and pediatrician contact. The captain will route the week with the medical facility in mind.
Sleep, sleep, sleep
The single largest under-6 charter mistake is underestimating the sleep environment.
The cabin AC must run quietly. Some older yachts have AC compressors that are loud enough to wake an under-2 from a nap. Specify "quiet AC" with the broker and ask for the captain to confirm in writing. The Heesen 50m hybrid series and the newest Sanlorenzo SD series are the quietest at anchor we have seen.
The cabin must be properly dark. A 5am sunrise in Hvar at the height of summer streams through any cabin that does not have blackout. Most yacht cabins have blackout. Not all do. Check.
The yacht must hold anchor in calm water all night. A yacht swinging on an open anchorage in a 12-knot breeze creates motion that an adult sleeps through and a toddler does not. Captains who have done family weeks know to anchor in protected positions. Captains who have not, do not.
The bedtime routine works aboard. The chief stew can run a bath, dim the lights, tuck in. She is good at this. Use her.
If sleep goes wrong, the whole week falls apart. Two parents on a yacht with a sleep-deprived toddler is a worse experience than the same family in a hotel.
What we have seen go wrong
The yacht the broker sold was the "family-friendly" yacht in the brochure. The yacht in question had a glass-walled hot tub on the sundeck, a sharp-edged dining table on the aft deck, and a sundeck-to-bridge stair that was an under-4 hazard. The broker had never been aboard. We had. The family changed yachts at our suggestion.
The Cyclades week. A first-time-charter family insisted on the Mykonos-Santorini route because the in-laws had done it. The meltemi blew 25-30 knots for three of seven days. The two-year-old vomited twice on a 35-mile passage. The parents called from Naxos and asked us to find them a hotel for the last three nights.
The "we don't need a nanny" week. Two parents, three children under five, a 14-day Croatia charter. Day 4 they called the broker for an emergency nanny. The local agent in Split found a Croatian nanny that afternoon. The remaining 10 days were the trip they had wanted. The nanny cost was 3% of the charter fee. The lesson was the lesson.
The yacht with a tired captain. The captain had four straight weeks of charters before the family week. The crew was running on autopilot. The chief stew was excellent but the rest of the team was tired. The family had a fine week, not a great one. Ask the broker what the yacht's charter schedule looks like immediately before your week. Five+ consecutive weeks of charter is a yellow flag.
Verdict
A yacht charter week with one or two children under six works best on a 45m to 55m modern motor yacht (Heesen 50m FDHF, Sanlorenzo SD126/132, Benetti Retreat 40M/50M) cruising Croatia or the Saronic Gulf or Menorca, with a dedicated nanny aboard, on a routine that runs 06.30 to 19.30 around the kids and lets the parents have a real adult dinner from 20.00. Total cost: €350,000 to €700,000 for a week including everything.
The decisions that matter: the right destination (calm, short hops), the right yacht (proper beach club, adjoining cabins, quiet AC), the nanny (yes, almost always), and the routine (the captain's routine, not yours).
The destinations to skip: the Cyclades, the Amalfi Coast, any week with a 30+ nautical mile single passage. The yachts to skip: open sportscruisers, most sailing yachts, anything without a real beach club.
For families with a mix of ages (kids under six plus older siblings), see the family charter with teens post for how to balance the routines. For the multi-generational version (kids plus grandparents), see multi-generational charter week. If the family pivot is to a stationary base instead of a charter week, the Mediterranean family villas on VillasForKings is the obvious comparison.
Frequently asked
Is there a minimum age for a baby on a charter yacht? No regulatory minimum. We have placed families with babies as young as three months. The constraint is the family's comfort with the medical access and the sleep environment, not the yacht.
Can the yacht supply a crib and high chair? Some can. Many cannot. Specify in writing four weeks before the charter. If the yacht does not have one, the broker arranges rental through the destination's family-rental service (€150 to €350 per week for both).
Will the chef cook separate meals for the kids? Yes. Brief the chef four weeks out with the kids' typical diet, allergies, and preferences. A good charter chef takes this seriously. A mediocre one will produce kid food that is technically correct and that the kids will not eat. Ask for the chef's CV.
Can we leave the kids with the nanny aboard while we have dinner ashore? Yes. The nanny stays aboard with the kids and the chief stew. Parents tender ashore for dinner and return by 11pm. This is normal. Brief the captain on the plan that morning.
What if a child gets seasick? The captain anchors. The crew has anti-nausea medication aboard. The chief stew is good at calming a queasy child. The captain reroutes the next day to calmer water. Seasickness is almost never trip-ending. Plan for the possibility.
How do you handle diaper waste on a yacht? The yacht has a black-water system and a dedicated waste bin. The chief stew handles it. Bring your own preferred wipes and diapers (yacht stocking is limited).
