Private Luxury Power Catamaran. Enjoy USVI Aboard MV Hydra
Book on Viator →Operated by Seas the Day Charters and Tours · Bookable on Viator
A fast catamaran changes how you see the islands. This private luxury charter from St. Thomas mixes comfort (you stay dry more than you’d expect) with standout snorkel stops aimed at turtles and reef fish. My favorite part is how the boat layout and onboard vibe make the day feel easy, even when the water is busy. One thing to plan for: fuel and captain gratuity are not included.
I like that the crew keeps the day moving with a sense of fun, not fuss, and they adjust when life runs late. The ride is built for groups up to 12, so you get a private feel without a huge boat crowd. Also, it runs outdoors, so the CDC/WHO-style cleaning and monthly crew testing add peace of mind without turning your day into a paperwork festival.

Private luxury power catamaran from St. Thomas: the value pitch

This is one of those USVI trips where the boat experience is the point, not just the ride to get there. For a fixed group price up to 12, you’re buying time on a stable, fast power catamaran with a crew handling the moves.
The value gets even better because the charter includes snorkeling gear, drinks (including beer), and U.S. national park fees. That means your day isn’t constantly switching gears into checklists and extra payments.

MV Hydra comfort and layout: where you’ll actually want to sit
MV Hydra is the kind of catamaran that makes you think about shade before you step aboard. The bow has spacious walk-through seating, transom seats, and custom bean bag chairs. In the back, you get expansive seating on custom marine couches, with both covered and uncovered areas.
That matters because USVI sun can be intense, and a 7-hour charter can still feel long if you only have one tiny patch of shade. Here, you can spread out, choose covered or open air, and stay comfortable between water stops.
The boat also includes a bathroom with washdown areas. That’s not flashy, but it’s a quality-of-life upgrade after saltwater and sand.
The 9:00 am start from Charlotte Amalie: harbor views and an easy rhythm
Your day begins around 9:00 am from the Charlotte Amalie area in St. Thomas. The plan starts in the historic harbor, with colonial-style views and cruise ship energy in the background.
Then you head past Water Island and into open Caribbean water. The pace is set up so you’re not stuck at the dock waiting for the day to happen. It feels like the boat turns your vacation on early, with the view doing the job while everyone gets settled.
If you’re trying to pack in snorkeling and beach time without feeling rushed, this start time helps.
Turtle Cove at Buck Island: why this stop is a big deal

One of the first water stops may be Buck Island, known for a protected marine sanctuary area and the famous Turtle Cove. This is the kind of snorkel setting where you’re not just looking for fish—you’re hoping for sea turtles, and the conditions are often set up for that.
The goal here is classic: clear water, coral, colorful reef fish, and a chance to spot sea turtles. You’re not carrying gear or guessing how it all works either. Snorkeling equipment is included, and the crew handles the on-and-off transitions.
Practical note: even with good snorkeling conditions, you’ll want to bring reef-safe habits. Use slow movements and keep your fins controlled so you’re not kicking sand into visibility.
St. John north shore: Honeymoon Beach or Maho Bay trade-offs

After Buck Island, you head toward St. John’s north shore. At that stage, you’ll typically hit one of two beach-and-water options: Honeymoon Beach or Maho Bay.
Here’s how I’d think about the choice. Honeymoon Beach tends to be a beach day with calm swimming vibes and a popular name for a reason. Maho Bay feels like another great fit for swimming and snorkeling, especially if you like the idea of sea turtles grazing in shallow areas.
The crew’s route flexibility is part of the fun. If you’re booking this as a first USVI trip, I’d take whichever stop they line up, because the real win is getting consistent water time plus snorkeling support.

Water Island’s Honeymoon Beach: lunch, swimming, and a laid-back bar feel

Next up, the itinerary typically includes Honeymoon Beach on Water Island. This is a calmer, more relaxed stretch of white sand, and it’s set up for swimming, relaxing, and even paddleboarding if you’re into that.
A beach bar atmosphere is part of the feel here, which means you can take a break from sea life watching without losing the vacation mood. Also, the Water Island timing is helpful because it gives the group a reset moment. After a snorkel stop, you get a chance to dry off, eat, and recharge.
If your group has mixed interests—some people want reef time and some want beach time—this is where it usually clicks. The boat format lets you keep the day social.
Brewers Bay near USVI: a quieter finish with more sea turtle odds

To end the day, you’ll often go to Brewers Bay. It’s a scenic stop near the University of the Virgin Islands, and it’s known for a peaceful vibe plus excellent snorkeling.
This is a good closer because it adds variety. You’re not repeating the first stop exactly, and the day ends with more water time rather than just watching the clock.
And yes, sea turtles remain part of the story here too. Not every trip is guaranteed, but the stop is chosen for the same reason you bought the charter in the first place.
Drinks, music, and staying dry: the onboard details that matter

This charter includes bottled water, soda/pop, and beer, plus alcoholic beverages in general through beer service. For a 7-hour day, that’s a big deal. You don’t want to spend your best vacation hours negotiating drink orders or running out mid-day.
There’s also a Fusion stereo onboard. You can set a fun soundtrack without turning it into a noise contest. It’s one of those small touches that makes the boat feel like your private hangout, not a floating classroom.
And because this is a power catamaran, the ride tends to be smoother than you’d expect from a fast boat. The description even calls out staying dry comfort, and in practice that’s what you care about: less constant spray on everyone and more time enjoying the water.
Crew service that feels personal: from patient boarding to fun facts
The captain and crew are included in your price, and the service style comes through in how the day runs. I’m especially impressed by how patient the crew is when schedules slip. One standout detail from operations is that they’ll work with you if you arrive late and still keep the day on track.
The crew also brings the story of the islands into the ride. Names you may hear include Capt Bryan, Caitlyn, Captain Aaron, Coleman, Captain Gregg with assistant Nate, and Captain Brian with crew members like JW and Hope. Different teams, same vibe: they’re friendly, interactive, and ready to keep things moving.
If your group includes non swimmers, that’s a real advantage. The setup allows people to stay on the boat while others snorkel, so nobody feels left behind or forced into the water.
And if you have someone who struggles with getting on and off the boat due to medical needs or age, the crew can adjust. That’s exactly the sort of benefit you only appreciate once you’re standing at a wet ladder and trying to keep everyone calm.
Price and fuel: what your final bill might look like
The base price is $1,595 per group for up to 12 people, and it’s been selling enough that the average booking is about 66 days in advance. If you’re traveling in peak season, that timing matters. Book early, especially if you want a specific day.
Now the part people often miss: fuel isn’t included. Fuel is $8 per gallon, and fuel averages 30–45 gallons. That puts the fuel portion roughly in the neighborhood of $240 to $360, depending on how much fuel they use for the day’s route and conditions. Gratuity for the captain isn’t included either.
So is it still good value? Yes, because you’re getting a full private charter, park fees covered, snorkeling gear included, and drinks included. If you added these pieces separately on a day with a typical group tour, costs add up fast.
COVID-safety approach without killing the fun
Seas the Day Charters and Tours uses a health protocol approach that’s geared toward keeping the day practical. The program partners with RayBiotech, and captains and crew are tested for COVID-19 each month. You’ll see them wearing a Covid Free bracelet.
After each trip, vessels are sanitized using CDC and WHO guidelines. Since this is primarily outdoors, masks are not required, but you can wear one if you want.
It’s a reasonable balance: cleaning and testing without making the whole experience feel like a medical setting.
Who should book this private charter?
You’ll like this if you want a USVI day that feels like yours. It’s a strong fit for:
- Families and friend groups up to 12 who want private time and flexible pacing
- People who want multiple snorkeling opportunities without managing gear rentals
- Birthday and milestone groups who want a memorable day at sea with onboard music and drinks
- Mixed ability groups where some snorkel and others relax on board
It’s also ideal if you’re the kind of person who hates wasting vacation hours on logistics. Pickup is offered, mobile ticketing is used, and the day’s flow is structured around water time.
Should you book MV Hydra from St. Thomas?
If you can swing the group price, I’d book it. The combination of private comfort, included snorkeling gear, and a crew that helps everyone enjoy the day makes this more than just transportation. It’s a well-rounded USVI experience aimed at swimming, reef time, and real sea turtle chances.
Just go in with one clear mindset: budget for fuel and captain gratuity, and pick the day with decent weather. With that plan, this charter is exactly the kind of St. Thomas trip that turns a normal vacation day into a highlight you’ll still talk about later.
