Imagine having your own boat for the day, swimming in beautiful spots, discovering little islands, and enjoying the Caribbean at your own pace. That’s the pitch behind a private charter out of St Martin, and it’s also where most travelers get stuck. Pull up a map, and St. Martin, Anguilla, and St. Barts sit close enough together to look interchangeable.
Each one offers a different kind of day on the water, and the best charters are built around who’s coming rather than a list of places pulled from someone else’s photos. Before anyone talks about boats, it’s worth working out which experience suits your group.
Three Very Different Days, All Within Reach of St Martin
You meet your captain at the confirmed marina or departure point, get settled on board, and head out. Once you clear the harbor, the whole island opens up in a way you can’t get from land, and that holds for a day along St Martin’s coast or a crossing to another island.
A Day Along St Martin’s Own Coastline
This is often the easiest choice for a first-timer, and it doesn’t mean settling for less. Depending on the route, you might cruise the coast, stop for a snorkel at Creole Rock, then head toward Tintamarre and Pinel for a swim.
It’s often when guests reach somewhere like Tintamarre and see that turquoise water for the first time that the day clicks. They’ve been enjoying the ride, chatting, taking in the coastline, and then suddenly they’re leaning over the side getting their snorkel gear ready. That’s usually the moment people realize the day is going to be something they remember.
Anguilla: Beaches and Clear Water
Anguilla is a different rhythm entirely. It’s known for its beaches and its water clarity, with spots like Little Bay and Sandy Island giving you the kind of stretch of sand and color you’d want to spend hours on rather than rush past. Guests who want a proper beach day, rather than several short stops, tend to gravitate here.
St Barts: A Different Character Altogether
St Barts feels distinct again. There’s coastline and bays worth exploring by boat, and the option to spend part of your day in Gustavia if you’d like a bit of town mixed in with your time on the water. It suits guests who want variety within the day, not just swimming.
How Weather and Sea Conditions Shape the Route
Some days the water is calm enough that any of these routes works well. Other days there’s more wind and swell, and that changes what’s sensible. Your captain adjusts the route to the conditions on the day, not the plan you had in your head last week, and that’s a good thing. A route that looks perfect on paper isn’t much fun if you spend it being tossed around instead of swimming.
What to Look for in a Private Charter Quote
A charter quote should tell you more than a price. Look for who’s included, what the departure point actually is, and whether the destination is fixed or flexible depending on conditions. It also pays to choose both the destination and the boat beforehand, because a boat that’s perfect for two couples who want to snorkel all day isn’t the same boat you’d want with young kids aboard for six hours.
The Question That Matters More Than the Itinerary
The most useful question to ask before booking isn’t “where does the boat go?” but “what kind of day would actually suit us?” Guests often arrive focused on a destination they’ve seen in photos, when a different route would better match their group’s pace, interests, and comfort on the water. Talking through that before you commit to a charter makes for a better day than any specific itinerary.
Don’t Try to Fit In Too Many Stops
A common mistake is planning too many stops for a single day. Each stop takes time — anchoring, swimming, getting back aboard, moving on — and by the third or fourth location, the pace starts to feel rushed rather than relaxed. Two or three stops done properly will give you more than five stops done quickly.
The Captain Sets the Tone
A good captain reads the group early and adjusts accordingly. Some guests want to move between spots all day; others want to anchor somewhere beautiful and stay. Captains who’ve been doing this in these waters for years know which anchorages work for swimming, which ones are better for snorkeling, and which spots tend to be quieter at different times of day.
What the Water Sounds and Feels Like
There’s something that changes when you’re out on the water and the engine cuts. The quiet is different from anything on land, and the color of the water around St Martin, Anguilla, and St Barts — from pale green in the shallows to deep blue further out — is genuinely hard to describe until you’re floating in it.
Practical Information
Best Time to Go
The dry season runs from December through April and offers the most reliable conditions for a boat day. The water tends to be calmer, the skies clearer, and visibility for snorkeling is generally at its best. That said, charters run year-round, and the shoulder months either side of peak season often combine decent conditions with less crowded anchorages.
Getting There
St Martin is served by Princess Juliana International Airport (SXM) on the Dutch side. Most charters depart from marinas on either the French or Dutch side of the island, and your operator will confirm the exact departure point when you book.
Costs
Private charters are priced per boat rather than per person, which means the cost per head drops significantly with a larger group. A full-day private charter typically runs from around $800 to $1,500 or more depending on the boat, destination, and what’s included. Trips to Anguilla or St Barts generally cost more than a coastal St Martin day due to the distance and any applicable ferry or entry fees. Always confirm what’s included — fuel, snorkel gear, food, and drinks are sometimes bundled and sometimes extra.
What to Bring
- Reef-safe sunscreen
- A change of clothes or dry bag for valuables
- Motion sickness medication if you’re prone to seasickness
- Water shoes for rocky entries
- Cash for tips — captains and crew are typically tipped separately
Frequently Asked Questions
Is a private boat charter from St Martin better than a group tour or ferry?
It depends on your priorities. Group tours and ferries cost less, but you’re on a fixed schedule with other passengers. A private charter gives you control over the pace, the stops, and the experience — particularly useful for families, couples, or groups with specific interests like snorkeling or avoiding crowds.
How do I decide between St Martin, Anguilla, and St Barts for a day trip?
Think about what you want from the day. St Martin’s coastline suits first-timers or those who want varied snorkeling stops. Anguilla is best for a slower, beach-focused day with exceptional water clarity. St Barts works well if you want some time in a town alongside your time on the water.
Can the boat trip be adjusted if the weather changes?
Yes. Captains monitor conditions and will adjust the route if wind or swell makes a planned destination impractical. This is a feature of a good charter, not a limitation — it means your day stays safe and enjoyable rather than sticking rigidly to a plan that no longer makes sense.
Is a boat day from St Martin suitable for families with young kids?
It can be, but the boat matters. Some vessels are better suited to younger children than others, and a shorter itinerary with calmer stops tends to work better than a long crossing. Mention the ages of your kids when enquiring so the operator can match you to the right boat and route.
Do I need snorkeling experience to enjoy stops like Creole Rock or Tintamarre?
No experience is necessary. Snorkel gear is typically provided, and the conditions at most stops around St Martin are calm enough for beginners. Captains and crew are generally happy to help first-timers get comfortable in the water before heading off on their own.
How many stops should we plan for in one day?
Two to three stops is the sweet spot for most groups. It gives you enough time at each location to actually relax and explore, without spending the whole day moving between places. If you have a specific priority — a long snorkel at one spot or a beach lunch — plan around that rather than trying to cover the most ground possible.
Booking a private charter from St Martin is straightforward once you’re clear on what kind of day you want. Getting that part right before you look at prices or itineraries will make the difference between a good day on the water and a genuinely memorable one.
