Private Luxury Power Catamaran. Enjoy USVI Aboard MV Hydra
The best part of this private St. Thomas charter is the freedom to shape a full day on the water. Aboard MV Hydra, a 40-foot Gemini Freestyle power catamaran, you can move from turtle snorkeling at Buck Island to beach time at Water Island without sharing the boat with strangers.
I like the stable, spacious boat, especially the shaded seating, marine couches, bean bags, bathroom, and walk-through bow. I also like the practical all-in setup: snorkeling gear, water, soda, ice, and beer are supplied, and the captain and crew are included in the booking.
The main thing to weigh is cost. The base price is $1,595 for up to 12 people, but fuel runs extra at about $8 per gallon, with typical use of 30 to 45 gallons, and gratuity is not included. That makes this a strong value for a full group, but a costly choice for only two or three people.
Key points at a glance

- Private boat for up to 12: Your group has MV Hydra to itself for about seven hours.
- A stable 40-foot power catamaran: The twin-hull design offers speed, room, and a steadier ride than a smaller open boat.
- Three to four possible water stops: The route may include Buck Island, St. John, Water Island, and Brewers Bay.
- Turtle watching is a major draw: Turtle Cove, Maho Bay, Honeymoon Beach, and Brewers Bay all offer chances to see sea turtles.
- Useful comforts are included: Snorkel gear, bottled water, soda, ice, beer, and the captain and crew come with the charter.
- Budget for fuel and a tip: Fuel is charged separately, and gratuity for the captain is not part of the listed price.
Starting in Charlotte Amalie at 9 a.m.
Your day begins at 9 a.m. in Charlotte Amalie, St. Thomas. The harbor gives you an early look at the island from the water, with colonial buildings, working waterfront views, and cruise ships often forming part of the scene.
The boat can pick you up, and the meeting point is near public transportation. Exact pickup arrangements should be confirmed when you book, since the details provided do not identify a single public dock for every departure.
A seven-hour charter gives you enough time to make several stops without turning the day into a race. That matters in the Virgin Islands, where the pleasure is often in the time between destinations: warm wind, open water, and the changing views of nearby islands.
Captains named in past outings include Bryan, Aaron, Gregg, Brian, and James, with crew members such as Caitlyn, Coleman, Nate, JW, and Hope. Your assigned team may be different, but the service style is clear: the crew handles the boat, explains the area, helps with water access, and adjusts the day to the group.

Why MV Hydra works well for a private group
MV Hydra is designed for comfort rather than bare-bones transport. The front has walk-through seating and custom bean bags, while the stern has covered and uncovered marine couches. You can sit in the shade, stretch out in the sun, or move around as the day changes.
The power catamaran design also matters. You get more speed than on a sailing catamaran, which helps fit several stops into seven hours. At the same time, the twin hulls offer a stable platform for people who are uneasy on smaller boats.
I would pay particular attention to the covered seating if your group includes older family members or anyone who does not want constant sun. One outing included an 87-year-old passenger, and the crew helped make boarding and moving around the boat easier. Another group included someone with medical limitations, and the crew offered extra assistance with getting on and off the boat.
That does not mean the charter is fully accessible in the formal sense. It is still a boat, and getting between the dock, deck, and water can require effort. If someone in your party has mobility concerns, explain the situation before departure so the crew can tell you what is workable.
There is also a bathroom with washdown areas. That is a small feature until you spend a full day at sea. It makes the trip more practical for families and anyone who prefers not to cut the outing short.
Buck Island and Turtle Cove

Buck Island is likely to be one of the first major stops. Its protected marine sanctuary includes Turtle Cove, where clear water and shallow areas can offer good conditions for seeing sea turtles and tropical fish.
The snorkeling gear is included, so you do not need to pack equipment for the group. The operator supplies the masks, snorkels, and related gear, though you should still bring your own swimsuit, towel, sun protection, and any personal equipment you prefer.
Turtle Cove is especially useful for mixed groups. Strong swimmers can spend more time in the water, while non-swimmers can stay aboard and still enjoy the scenery. One birthday group included several people who did not swim, and everyone was able to take part in the day without forcing the whole party into the water.
Water conditions can change, and wildlife sightings are never guaranteed. The appeal is the chance to watch turtles grazing in clear Caribbean water, not a promise that every person will see one. Listen to the captain’s instructions and give the animals room.
St. John’s north shore and Maho Bay

From Buck Island, the charter may continue toward St. John. The north shore is a fine contrast to the harbor at Charlotte Amalie, with a quieter feel and inviting coves reached by boat.
Honeymoon Beach or Maho Bay may serve as the next swimming and snorkeling stop. Maho Bay is well known for shallow water where sea turtles may feed. It can be a good choice for families and cautious swimmers because the focus is not only on serious snorkeling. You can float, wade, watch for turtles, or stay aboard.
Honeymoon Beach offers another kind of pause. The emphasis here is simple: swim, sit, and enjoy the shoreline. The schedule is flexible enough that your captain can judge which stop suits the conditions and the mood of your group.
I like this part of the itinerary because it avoids making the whole day one long snorkeling session. Some people want fish and coral. Others want a calm swim, a beach, or a place to sit in the shade. A private charter gives your group a better chance of balancing those preferences.

Water Island for a slower afternoon

The itinerary may include Honeymoon Beach on Water Island as well. This is a separate stop from the possible Honeymoon Beach visit on St. John, so ask your captain how the day is being arranged.
Water Island offers calm water, white sand, and a laid-back beach-bar setting. It is a natural place for lunch, swimming, or paddleboarding. Food is not listed as included, so plan to pay separately for any meal or beach-bar purchase.
One of the strongest uses of this stop is simply giving everyone a break. After snorkeling, you can step onto the sand, dry off, and spend time together without the constant motion of the boat. If your group has children, older family members, or non-swimmers, this kind of shore time can be just as valuable as the reef stops.
The tradeoff is that every beach stop uses part of your seven hours. If your top priority is snorkeling, tell the captain early. If your group wants a relaxed birthday, family day, or lunch by the water, allow the itinerary to breathe.
Brewers Bay as a peaceful final stop

Brewers Bay, near the University of the Virgin Islands, may be used toward the end of the trip. It is described as a quiet spot with good snorkeling and another chance to see sea turtles.
This can be a pleasant final water stop because it offers a calmer setting after the more active parts of the day. You may find yourself snorkeling again, swimming near the boat, or simply enjoying the last stretch of open water before returning to St. Thomas.
The precise order of stops is not fixed. Weather, sea conditions, boat traffic, and your group’s preferences can affect the route. That flexibility is one of the chief reasons to book a private charter instead of a fixed group cruise.
Drinks, music, and onboard comfort

MV Hydra carries bottled water, soda, ice, and ice-cold beer. Beer is the only alcoholic drink specifically listed, so do not assume that wine or spirits are supplied.
The boat has a FUSION stereo, allowing your group to listen to music during the ride. Keep the volume at a level that works for everyone, especially when the crew is giving safety instructions.
The bow seating, bean bags, covered stern couches, and open-air areas give you several ways to settle in. I would still bring a hat, reef-safe sun protection, sunglasses, and a dry bag for phones. Those items are not listed as included, and a day on the water offers little shade once you move away from the covered seating.
The boat is promoted as keeping passengers dry and comfortable while underway. That is useful, but it does not mean you should dress as if you are staying on land. Spray and wet boarding areas are always possible around a boat, so quick-drying clothing is the sensible choice.
What the $1,595 price really means

The advertised price is $1,595 per group, for as many as 12 people. At full capacity, that works out to roughly $133 per person before fuel and gratuity. Add estimated fuel of 30 to 45 gallons at $8 per gallon, or about $240 to $360 total, and the group cost becomes approximately $1,835 to $1,955 before a captain’s tip.
For 12 people, that is a reasonable way to secure a private boat for seven hours, especially since the price includes the captain and crew, snorkeling gear, water, soda, ice, beer, and national park fees. For six people, the base cost alone is about $266 per person, before the added charges. For two people, the math becomes difficult to justify.
The value improves if your group would otherwise pay for several separate activities. You receive transportation by sea, multiple possible stops, snorkeling, beach time, and a private setting in one day. You also avoid sharing the schedule with a large crowd.
Be clear about the fuel charge before departure. The available information gives a fuel rate and an average range, but not a fixed final amount. Gratuity is also separate. The crew’s help with families, older passengers, and people who need assistance may influence what you choose to tip.
Who should book MV Hydra
I would recommend this charter most strongly for families, birthday groups, reunions, and friends traveling together. The private format lets swimmers and non-swimmers share the same day without splitting up.
It also suits you if comfort matters. The covered seating, bathroom, stable catamaran design, and room to move are meaningful on a seven-hour outing. The captain and crew can help shape the day around snorkeling, beaches, or a mix of both.
This is less compelling for a couple or very small group unless the private experience is the main point. It is also not the best match if you want to visit the British Virgin Islands. Visiting the BVI is specifically excluded.
The tour is suitable for most people, but boat access and water activities still require basic care. Mention medical or mobility concerns ahead of time. The crew has accommodated passengers with limited mobility, but the available information does not promise a fully accessible vessel.
Booking, weather, and cancellation details
The experience is often reserved well ahead, with an average booking lead time of 66 days. That suggests you should plan early if your dates are fixed, especially during busy periods.
You can cancel for a full refund up to 24 hours before the start time. Changes or cancellations made inside that 24-hour window are not accepted for a refund. Cutoff times use local time in the Virgin Islands.
The trip requires good weather. If poor weather forces cancellation, you can choose a different date or receive a full refund. Since the route depends on sea conditions, keep some flexibility in your plans if possible.
Final verdict: Is MV Hydra worth booking?
Book MV Hydra if you have a group large enough to spread the cost and want a private day that combines snorkeling, turtles, beaches, and time aboard a comfortable boat. The strongest reasons are the roomy catamaran, flexible route, included gear and drinks, and crew assistance for mixed-ability groups.
Before paying, confirm the pickup point, expected fuel cost, and your preferred balance of snorkeling and beach time. If you have only two or three people, compare the total price carefully. For a full family group or celebration, though, this charter offers a practical way to see several parts of the USVI in one well-paced day.
