Private Full Day Guided Snorkeling or Diving Charter in St Thomas
Book on Viator →Operated by Aqua Marine Dive Center · Bookable on Viator
Want clear water without the crowds. This private St Thomas charter uses a 42-foot eco-friendly boat and lets you steer the day with your captain, from Buck Island to protected marine zones.
I love that snorkeling gear is included and you’re not stuck figuring things out alone. You also get a full set of stops built around actual sea life chances, including wreck scenery at Shipwreck Cove and more time in the calmer waters near Little St. James and Greater St. James.
One thing to consider: you’ll need to be a capable swimmer in open water, since some shoreline breaks (like Secret Harbour) require you to swim or float in.

Key highlights you’ll feel in real life

- Private 42-foot eco-friendly boat for your group means fewer waiting games and more time at the waterline.
- Buck Island, Shipwreck Cove, and the Cartanza wreck give you more than just coral—there’s a story under the surface.
- Secret Harbour stop can include restaurant lunch, but you’ll swim/float in from as close as the boat can get.
- Little St. James marine protection zone focuses your time on corals and schools of fish.
- Christmas Cove at Greater St. James is built for relaxed snorkeling with a good shot at stingrays and colorful reef fish.
- Snacks, soft drinks, and Pirate Punch (rum punch) for adults 18+ keep morale up on a full day out.
Start at Saga Haven Marina: how your day kicks off

This charter starts bright and early at Saga Haven Marina, where you meet the crew on the dock at the start point near 6117 Estate Frydenhoj. The activity begins at 8:30am, and you’ll check in about 30 minutes before that—time for paperwork, gear fitting, and settling into a rhythm that doesn’t waste daylight.
The boat is set up for your group’s day, with a USCG licensed captain running the schedule. You’ll get your snorkel setup (mask, fins, snorkel, and a floatation device), and if you’re doing the scuba option instead of snorkeling, the crew coordinates for that choice as well.
Practical note: transportation to and from the meeting spot isn’t included. If you’re relying on rides, build in extra buffer time. These morning check-ins matter because the best water conditions don’t wait around.

Picking your reef plan with the captain on the water

The best part of a private charter is control. You’ll talk with the captain and crew about what you want most—sea turtles, wreck views, easy snorkeling, or a more active swim day—and they’ll work that into the route based on conditions.
That matters more than it sounds. St Thomas waters can change through the day, and the crew’s job is to match you with the best options they can safely access. The itinerary includes several distinct stop styles, so even if one area isn’t perfect that day, you’re still moving through other strong choices.
You’ll also get cruising time between sites. In a group tour, that can feel like dead time. Here, it’s part of the experience—time to ask questions, listen for what’s next, and get your bearings before you gear up again.
Little Buck Island and Shipwreck Cove: wreck scenery plus reef life

Your first big underwater payoff is Little Buck Island. The day is structured so you hit the area with enough breathing room to enjoy multiple chances in the water.
At Buck Island, you’ll snorkel at two unique sites. One of the standout features is the Cartanza wreck in Shipwreck Cove. Even if wrecks are not your main obsession, wreck habitat is often where you’ll find curious fish life moving in and out of the structure.
You can expect the crew to share stories about the area as you cruise, which is one of those small touches that changes how the stop feels. With the right framing, you stop looking at the water like a video game and start noticing the details: where fish gather, how currents move around the reef, and how visibility changes with where you enter.
If you’re the type who likes photos, this is also a good moment to do test shots before you hop in for your main swim. The wreck area can offer strong visual reference points—use that.
Secret Harbour: lunch may be on shore, but you’ll work for it

Next comes Secret Harbour, usually a good place to slot in a lunch break. The boat can get close to shore, but here’s the key detail: you’ll need to swim or float to the beach to enjoy lunch at the restaurant there if you want it.
That’s the trade-off. It’s not dockside convenience, so you’ll want a calm plan for the swim-in and back-out. If you’re traveling with kids, weak swimmers (even if they’re wearing gear), or anyone who hates open water, this is where you should think hard before you choose the beach lunch.
The time window here is about one hour, so it’s not meant to become a long detour. Think of it as a quick reset: eat if you want, rinse your gear if needed, then head back ready for the next snorkeling stretch.
Also remember: meals aren’t included. The restaurant is an option, not a provided lunch.
Little St. James ledges: protected marine waters and corals

Then you head to the Ledges of Little St. James, a short ride away. This stop is tied to a protected marine park, which is exactly the kind of setting that helps reefs and fish populations stay healthier over time.
What you’re looking for here is coral detail and fish schooling. The stop is described as a mix of hard and soft corals, plus the chance to see schools of fish like bluestriped grunts and other blue-toned reef species.
One of the practical benefits of a protected zone is that the crew typically knows the rhythm: where the reef structure is, how people should enter and exit, and how to keep time in the water efficient without feeling rushed.
If you’re snorkeling, this is the part of the day where you’ll likely spend more time watching than moving. The ledges tend to reward slow, steady glances, not sprinting from one spot to the next.
Christmas Cove at Greater St. James: relax, then snorkel again

You’ll roll next to Christmas Cove at Greater St. James. The schedule gives you relax time while the boat heads over, and there’s a flexible window for snorkeling before or after lunch depending on how you chose to pace Secret Harbour earlier.
Christmas Cove is known for reef fish and ray sightings. You might see spotted trunkfish, French angelfish, and southern stingrays. That list is useful because it’s not just generic “fish everywhere.” It gives you something concrete to watch for as soon as your mask goes on.
If you want a good experience with minimal stress, this is also a strong late-day stop. By now you’ll have a rhythm: gear fitted, swim comfort assessed, and your confidence is likely higher than it was at the first site.
Just keep a realistic expectation: the ocean is still the ocean. Even with a great crew, sightings can vary by day and water conditions. The upside is the day isn’t built around one single “maybe” moment—you have multiple sites.
Gear, drinks, and safety: what’s actually included

This charter isn’t light on what it provides. You’ll get:
- snorkeling mask, fins, snorkel, and a floatation device
- snacks (cookies, crackers, chips, water, soda)
- water and soft drinks
- Pirate Punch (rum punch) for adults 18+
- a certified snorkel guide
- a USCG licensed captain
That combo matters for value. Many half-day snorkel trips give you gear but not the full comfort package. Here, the snacks and drinks help you stay energized through the full 6 to 8 hour day.
The alcohol piece is optional, and it’s specifically for adults 18+, which keeps things clear for families. I’d treat it as a bonus, not a plan—keep yourself alert and hydrated.
Safety-wise, the rules are straightforward:
- You must be able to swim comfortably in open water without assistance
- Service animals are allowed
- Age 5 and up, with children accompanied by an adult at all times
If you’re deciding between snorkeling vs the scuba option, the crew can guide you based on your experience level and comfort. Either way, you’re in a private setup with a captain and guide handling the big decisions.
Eco-friendly 42-foot boat: why the size and setup feel better

A 42-foot vessel changes the experience in ways you can feel. More space usually means less crowding at gear-up time and fewer bottlenecks during boarding and water entry.
The boat is also described as eco-friendly, which is a positive point for travelers who care about minimizing impact in places they love. And because it’s designed for your group, you’re not stuck sharing equipment and rules with strangers who may not follow the plan.
In plain terms: fewer moving parts on the boat usually means smoother water time. You spend less energy negotiating for space and more energy watching what’s under you.
Price and value: what $3,225 buys on a private charter day
The listed price is $3,225 per group (up to 1), and that’s for a full-day private outing. That price can feel steep until you break down what’s included and how many stops you’re getting access to.
Here’s how I see the value:
- Private boat access for your group, not a shared tour
- Multiple snorkeling sites across several locations (not just one spot and done)
- Gear included (you don’t have to rent masks and fins separately)
- A certified guide and licensed captain, which you’re paying for whether you snorkel or do scuba sessions
- Snacks and drinks across the day
If you’re traveling solo and the booking system shows “up to 1,” this can still make sense if you’re prioritizing a custom route and want to avoid crowded water. If you’re a family or small group, it can become easier to justify because the private format spreads the cost.
Best fit: groups that want control—people who care about timing, prefer quieter water, and don’t want to gamble their day on a shared schedule.
Who should book this full-day charter
This charter is a smart fit if:
- you want private time on the water
- you care about seeing more than one reef area (wreck, protected marine park, and cove snorkeling)
- you’re comfortable in open water and can swim confidently
- you like the idea of customizing stops with the captain
It’s less ideal if:
- nobody in your party can swim comfortably without assistance
- beach lunch (Secret Harbour) would be stressful for your group
- you’re trying to keep costs low with a shared tour
Families can do well if everyone meets the swim comfort rule and kids are paired with an adult in the water as required.
Practical tips that make the day smoother
You’ll get the gear, snacks, and drinks, but you can still improve your odds of a great day.
Bring:
- your own swimwear basics and a plan for keeping items dry
- something for sun protection (because you’ll be on the boat for hours)
- a towel and a light change of clothes for the ride back
In the water:
- go slow at your entry; fine-tune your mask fit right away
- if you’re doing Secret Harbour beach lunch, treat the swim/float back as part of the schedule, not an afterthought
Also, hydrate. Pirate Punch is fun, but you’re out for 6 to 8 hours, and the sun is real.
Should you book this St Thomas charter?
If you want a day that feels intentional—multiple reef stops, a captain who can work with conditions, and a private boat setup—this is the kind of charter I’d book. The value isn’t just the price tag. It’s the structure: gear included, guide onboard, snacks and drinks handled, and a route that aims at specific places like Shipwreck Cove and the protected waters near Little St. James.
Book it especially if your group is comfortable in open water and you’d rather pay for quality time than fight crowds. Skip it if swim confidence is an issue, because Secret Harbour and the overall format still expect you to be at ease in the water.
