Taking kids on a boat trip in the Caribbean might sound like a lot to manage, but in practice, it’s one of the easiest and most memorable things a family can do on vacation. Children love the water, they love discovering new beaches, and they love the sense of adventure that comes with being out at sea. For parents, it’s a chance to relax while someone else handles the navigation, the food, and the plan for the day.
St. Barth and St. Martin are ideal for family charters. The distances are short, the waters are warm, and there’s plenty to see and do without long stretches of open ocean.
Choosing the right boat
For families with young children, stability and space are key. Catamarans are usually the best option — they’re wider, more stable, and offer flat deck areas where kids can move around safely. There’s often a shaded area too, which makes a big difference under the Caribbean sun.
If your kids are older and more comfortable on the water, a speedboat can work just as well, especially for half-day trips. Our article on how to pick the right boat for your Caribbean trip covers the differences between boat types in more detail.
Best destinations for families
Not every beach or anchorage is equally suited to children. The best family-friendly stops tend to have calm, shallow water, sandy bottoms, and easy access from the boat. Here are a few favorites:
Pinel Island, off the northeast coast of St. Martin, is a top pick. The water is calm, shallow, and crystal clear — ideal for young snorkelers. There are two beach restaurants serving grilled food, and the whole setting is relaxed and low-key. Kids can play on the sand while parents eat just a few meters away.
Colombier Beach in St. Barth is another excellent choice. Accessible only by boat or a hiking trail, it’s always quieter than the more popular beaches. The snorkeling is fantastic and the bay is sheltered, making it a safe spot for confident swimmers. If your children enjoy sea life, our article on where to swim with turtles in Saint-Barth will give you more ideas along the same lines.
Tintamarre Island is great for slightly older kids. The snorkeling here is exceptional — sea turtles are frequently spotted — and the uninhabited island adds a layer of adventure. Just keep in mind that there are no facilities, so everything needs to be brought on board.
Practical tips for families
Sun protection is non-negotiable. Even with cloud cover, the Caribbean sun is strong, and the reflection off the water intensifies it. Bring reef-safe sunscreen, hats, rash guards, and make sure there’s shade available on the boat. Hydration matters too — kids get dehydrated faster than adults, especially when swimming.
Snacks go a long way. Even though most charters provide food and drinks, having familiar snacks on hand for younger children keeps things smooth. Same goes for a towel or light layer — the breeze picks up on the water and wet kids can get chilly faster than you’d expect.
For very young children, discuss your plans with the crew beforehand. They can adjust the itinerary to keep travel times short, choose the calmest anchorages, and plan the day around nap times and meals.

Why kids love it
There’s something about being on a boat that resets the whole family dynamic. Kids aren’t staring at screens — they’re watching for fish, jumping off the back of the boat, learning to snorkel, or just lying on deck looking at the sky. It’s a rare kind of unplugged experience, and it tends to produce the best vacation memories.
The crew at Infinity Boat is used to welcoming families. They’ll help set up the day so everyone — toddlers to teenagers — has a great time. Just let them know your children’s ages and what they enjoy, and they’ll take care of the rest.
