Three generations on one boat sounds like the setup for a comedy, or a disaster. We have done it twice now, my parents in their seventies, us in our forties, and two grandchildren under twelve, cruising the French coast for a fortnight each time. It worked, both times, but only because we planned for the spread of needs rather than pretending everyone wanted the same holiday. A grandparent and a nine-year-old want very different things from a day afloat, and the art is building a week that serves both without exhausting the middle generation who run it.
Start with the boat: a catamaran solves most of it
If you take one decision seriously, make it the hull. For a mixed-age crew with grandparents aboard, a catamaran is worth every extra euro. The two hulls barely heel, so an older person can move around without being thrown off balance, and the reduced motion cuts seasickness for everyone. Just as important, the layout is mostly on one level: a flat bridgedeck saloon and cockpit, wide side decks, and big steps rather than the steep companionway ladder of a monohull.
We looked specifically for wide gangways, generous handrails, plenty of shaded deck seating, and a cockpit you can reach without climbing. For a grandparent with a dodgy hip or knee, those features are not luxuries, they are the difference between joining in and being stuck in one seat all week. The full case for the hull type on French waters is in catamaran cruising in France, and it is the article I wish I had read before our first booking.
Boarding is the real obstacle, not sailing
Older crew rarely struggle with the sailing. They struggle with getting on and off the boat. A fixed harbour wall at low tide can present a vertical climb that is simply impossible for a seventy-five-year-old, while a floating pontoon keeps the step consistent at any state of tide.
So we chose marinas with floating pontoons wherever possible and rang the capitainerie ahead to ask for a berth near the facilities with a flat walk to shore. The better French marinas have lifts where there are level changes and accessible shower blocks, and the staff are used to helping. We also carry a small folding boarding step and rig the passerelle, the boarding plank, carefully every time so my father has a handrail and a flat tread. The norms of dealing with the harbour office are covered in French port etiquette and the capitainerie; a polite phone call the day before has never failed us.
Short passages, calm water, no heroics
A multigenerational crew sails at the pace of its least robust member, and that is the grandparents. We planned legs of 2 to 3 hours in settled weather, never two demanding days in a row, and treated a rough forecast as a day off rather than a test. Older bodies tire faster, sunburn faster, and recover slower, so we built rest into the schedule rather than apologising for it later.
France is ideal for this because the sheltered cruising grounds are stitched together with short, calm passages. The Gulf of Morbihan is almost an inland sea, with tiny hops between islands and minimal swell, which is why it is our favourite multigenerational ground; the guide to the Gulf of Morbihan by boat maps out exactly the sort of short, protected legs that suit older crew and young grandchildren alike. On the Mediterranean side, the lunchtime hops between Riviera bays do the same job in warmer water.
Two generations, two timetables
The genius move, the one that saved both trips, was to stop forcing everyone to do everything together. My parents loved a slow morning, a gentle sail, a sundowner on deck and an early dinner aboard. The children wanted beaches, dinghy adventures, and a town with an ice cream queue. Rather than compromise both into mediocrity, we ran parallel tracks.
A crewed charter does this for you, since the crew can take the kids snorkelling off the back while the grandparents watch the sunset with a glass of wine. We bareboat, so we did it ourselves: one parent ashore with the children, one aboard with the grandparents, swapping over. The shade-and-seating cockpit became the grandparents' base, and the dinghy became the children's freedom machine. Everyone got their holiday. For the children's side specifically, the independence ideas in family beach anchorages in France kept the younger ones happily occupied while the older generation rested.
Health, heat and the things that catch you out
Older crew need their medical ducks in a row before they ever step aboard. We carry everyone's medication in a labelled waterproof box with a printed list of doses, a copy of prescriptions, and the GHIC details for the British members so that French healthcare is straightforward if needed. We note the nearest pharmacy and doctor at each planned stop, because a grandparent's minor ailment is the most likely reason your week needs a Plan B.
Heat is the quiet danger. In a Mediterranean July the cockpit can sit above 35 degrees in full sun, which is dangerous for an older person, so shade and hydration are not optional. We rigged the bimini permanently, kept cold water flowing, and scheduled the strenuous bits for the cooler ends of the day. A grandparent who overheats can spoil a week as surely as a storm.
Sleeping arrangements and the small stuff
The things that sink a multigenerational week are rarely dramatic. They are the small frictions. Cabins are the first: grandparents need the easiest berth to get into and out of, ideally a full-height cabin near the heads, not the forepeak you reach by climbing over someone. We always give the most accessible cabin to the oldest crew, full stop, and the children take the awkward berths because they bounce out of bed regardless.
Noise is the second. Children wake early and want to be loud; grandparents want a slow start. A catamaran helps here too, because the hulls are physically separated, so an early-rising eight-year-old in one hull does not wake a grandparent in the other. On a monohull we learned to set a quiet-until-eight rule that everyone, just about, respected.
The third is pace of meals. Older crew like to eat earlier and more calmly than a pack of hungry children allows. We split it: an early, quiet dinner aboard some nights for the grandparents and us, with the children fed first and sent to the cockpit, and a livelier meal ashore on others. France's habit of long, late summer evenings actually suits this, because there is plenty of daylight to stagger the day.
A short list for the mixed crew
The kit that made three generations work:
- A stable, level-living catamaran with wide decks and handrails
- A folding boarding step and a well-rigged passerelle
- A permanent bimini and plenty of cool drinking water
- Labelled medication boxes, prescriptions, and GHIC or insurance details
- A 100 newton lifejacket for each child under 30 kg, as French Division 240 requires, and a comfortable one for the grandparents that is easy to fit
- A dinghy or paddleboard so the children can roam while the grandparents rest
Why it is worth the effort
Running a three-generation boat is more work than a couple's cruise, no question. The middle generation does most of the lifting, literally and figuratively. But watching my father teach my son to coil a line, or my mother and granddaughter swimming off the back in a flat Breton bay, is the reason we keep doing it. France gives you the calm water, the short passages, the accessible marinas and the warm anchorages that make it possible. Choose the right boat, sail gently, run parallel timetables, and three generations come home having had, genuinely, the same good holiday in three different ways.
