Start with turquoise water and a flexible plan. This private St. Thomas charter gives your group a 36-foot power catamaran and a captain who can shape the day around snorkeling, swimming, beaches, lunch, or a Painkiller stop. You are not locked into a crowded boat schedule, which makes the outing especially appealing for families and groups of friends.

I like the easy water access provided by the long swim ladders, fresh-water shower, changing area, and marine head. I also like the range of choices, from sea turtles at Maho Bay to pizza delivered by boat at Christmas Cove. The main caution is cost: the $995 group price is not the final bill, since fuel and the customary captain’s gratuity are extra.

Key points to know before you book

Full or Half Day Private Power Catamaran- USVI Beach and Snorkel - Key points to know before you book

  • Your group gets the whole 36-foot catamaran: Up to 12 people can join under US Coast Guard capacity rules, with no unrelated passengers sharing the boat.
  • The seven-hour route is flexible: You can work with the captain to adjust snorkeling, beach time, lunch, and sightseeing to suit your group.
  • Maho Bay is the turtle stop: Sea turtles feed in shallow seagrass beds, making this one of the most appealing snorkel locations on the route.
  • Fuel adds $160 to $240 on average: The boat uses about 20 to 30 gallons, billed at $8 per gallon after the charter.
  • Captains receive especially warm praise: Aaron, Chris, and Hillary are singled out for good service, local knowledge, and adapting the day to each group.
  • The front netting needs a quick check: One past outing had torn netting and expired sodas, though the operator said repairs and restocking were being handled.

Why a private boat changes the day

Full or Half Day Private Power Catamaran- USVI Beach and Snorkel - Why a private boat changes the day

The biggest advantage here is control. You are not simply following a fixed loop with a boatload of strangers. At the start of the charter, you can tell the captain what matters most: more snorkeling, a quiet swim, a beach stop, a restaurant lunch, or a little of everything.

That flexibility is useful because groups rarely agree perfectly. Strong swimmers may want several snorkel stops, while children or less confident swimmers may prefer a beach and calm water. A private boat lets the captain adjust the pace instead of making everyone follow one plan.

The boat is certified for up to 12 people, though the experience will feel more spacious with a smaller group. Six people, for example, can spread out easily between the bow nets and shaded stern. With 12 aboard, you still have legal capacity and plenty of seating, but the private setup becomes more valuable for the company and flexibility than for personal space.

The power catamaran design should appeal to anyone who dislikes a rough ride. You have open space at the front, shade at the rear, and easy movement around the boat. The long ladders matter more than they may sound. They make repeated trips into the water less awkward, especially for children and anyone who does not enjoy climbing a short, steep boat ladder.

Leaving American Yacht Harbor in Red Hook

Full or Half Day Private Power Catamaran- USVI Beach and Snorkel - Leaving American Yacht Harbor in Red Hook

The meeting point is American Yacht Harbor in Red Hook, on Smith Bay Road. The boat returns here at the end of the day, so you do not need to arrange a separate return transfer from another part of St. Thomas.

Once underway, you get views across the surrounding Virgin Islands as the boat heads toward St. John and nearby cays. The crossing itself is part of the pleasure, with open water, island views, and a captain who can point out landmarks and share local context.

Captain Hillary received especially strong praise for explaining history and landmarks during the ride. That kind of narration adds value to a private charter because the boat is not only transportation between swim stops. You get a more personal sense of where you are, and you can ask questions as the day unfolds.

Drinks are included, with bottled water, soda, and beer aboard. Floats and noodles are also provided. You should still think of this as a boat day rather than a catered cruise. Lunch is included as a stop or arrangement, but the exact restaurant and food cost are not specified in the details provided, so confirm how your preferred lunch choice will be handled.

Lovango Cay for snorkeling or a beach club stop

Lovango Cay is planned as the first major stop. It offers a choice between snorkeling around the island and relaxing at an upscale beach club. That choice sets the tone for the rest of the day: active water time if you want it, or a slower stop if your group needs to ease into the morning.

The exact snorkeling conditions can change with weather and water movement. Your captain chooses the best practical spot for the day, rather than promising that every group will see the same marine life. The boat carries quality snorkel equipment, so you do not need to pack your own unless you prefer a personal fit.

This is also a useful stop for mixed-age groups. Some people can snorkel while others stay on the boat or enjoy the beach setting. A private charter works well here because nobody has to sacrifice the entire stop for a family member who would rather sit in the shade.

Honeymoon Beach and the calm north shore of St. John

The route continues along St. John’s north shore to Honeymoon Beach. The setting is suited to swimming and paddleboarding in calmer water, making it a gentler break from open-water cruising and snorkeling.

You should expect the captain to judge the stop based on conditions and your group’s interests. If everyone wants fish and coral, you may spend less time at the beach. If the group wants to float, swim, or simply enjoy the view, Honeymoon Beach provides a change of pace.

This stop also shows why the private format has real practical value. A fixed group excursion may give you only a short window at each location. Here, your captain can listen to what people actually want during the day. Captain Hillary is specifically praised for setting a pace that matched the group’s interests, which is exactly the sort of service that makes a private charter worthwhile.

Maho Bay and the best chance for sea turtles

Full or Half Day Private Power Catamaran- USVI Beach and Snorkel - Maho Bay and the best chance for sea turtles

Maho Bay is the signature wildlife stop. Sea turtles feed in shallow seagrass beds here, so you can snorkel from the boat rather than needing a long shore transfer.

The shallow water is helpful for people who are comfortable snorkeling but do not want a challenging swim. It also gives you a better chance to watch turtles at a manageable distance. Sightings are never guaranteed, since these are wild animals, but the habitat makes Maho Bay a strong choice for the route.

The turtles are one of the most praised parts of the outing. One group saw large turtles near St. John, while another described a half-day charter that included turtles, stingrays, eels, barracudas, sea urchins, coral, and many fish. Those sightings show the range of marine life you might encounter, though you should not treat a past sighting list as a promise.

Captain Aaron is praised for being both fun and well informed, and Captain Chris is credited with finding excellent snorkeling locations. Their role matters here. The quality of a wildlife stop depends not only on the site but also on where the captain positions the boat and how well the crew reads the conditions.

Christmas Cove, Pizza Pi, and lunch afloat

Full or Half Day Private Power Catamaran- USVI Beach and Snorkel - Christmas Cove, Pizza Pi, and lunch afloat

The final major area is Christmas Cove off St. James Island. The cove is known for calm anchorage and colorful reefs, so it can work as another swim or snorkel stop.

Lunch is available in several styles. You may eat onboard, stop at a beachside restaurant, or order from Pizza Pi, the floating restaurant famous for delivering fresh pizza directly to boats. This is one of the outing’s more unusual details. You get a memorable lunch setting without giving up time on the water to sit inside a conventional restaurant.

The exact lunch plan should be discussed with the captain early in the day. Captain Hillary’s outing included Lime Out, where shrimp tacos were a highlight, followed by another snorkeling stop. That shows how the schedule can be shaped around food and water time rather than treating lunch as a long interruption.

Keep in mind that restaurant purchases are not listed among the included items. Water, soda, beer, snorkel gear, captain service, fees, and taxes are included, but food costs and some restaurant arrangements may be separate. Ask before ordering so the final bill does not surprise you.

What is included, and what costs extra

Full or Half Day Private Power Catamaran- USVI Beach and Snorkel - What is included, and what costs extra

The $995 price covers the group, not each person, and the boat accepts up to 12 individuals. For a full group, that works out to about $83 per person before fuel and gratuity. For six people, it is about $166 per person before those additions. The value improves as your group gets larger, provided everyone wants the same private-boat experience.

Included items are:

  • Snorkeling equipment
  • Bottled water
  • Soda
  • Beer and other listed alcoholic beverages
  • Floats and noodles
  • Captain’s fee
  • All listed fees and taxes

Fuel is separate at $8 per gallon. Typical use is 20 to 30 gallons, so budget approximately $160 to $240 for fuel. The actual amount is billed at the end of the day, not folded into the advertised group price.

A gratuity for the captain is also not included. The customary amount is 18 to 20 percent. Since the captain shapes the route, handles the boat, helps with water access, and often provides narration, you should include this in your budget from the start.

The cleanest way to think about the cost is this: you are paying for a private day on the water, not merely transportation to a beach. If your group values privacy, flexibility, and a captain who can adjust the plan, the price can make sense. If you only want one short snorkel stop, a shared excursion may be better value.

Comfort, equipment, and the small warning signs

Full or Half Day Private Power Catamaran- USVI Beach and Snorkel - Comfort, equipment, and the small warning signs

The boat has several features that make seven hours more comfortable. The shaded stern provides relief from the sun, while the bow nets offer a place to stretch out when conditions allow. A marine head, fresh-water shower, and changing area are important on a full-day outing, especially when you are moving between snorkeling and dry clothes.

The long swim ladders are a real plus. They make boarding after a snorkel less tiring and are friendlier for children and older adults than a narrow ladder.

There is one maintenance concern worth noting. One past group found the front netting torn, which meant they could not lie on the nets or walk across them. The same group also reported expired sodas. The operator responded that repairs were being handled and that the drink issue was being addressed.

That does not erase the problem, but it gives you a useful pre-departure question: ask whether the front netting is currently in good shape and confirm that the drinks have been restocked. A quick check can prevent disappointment if the bow nets are a major reason you chose a catamaran.

The captains are a major part of the value

The strongest service comments focus on the captains. Aaron is praised for being fun, informed, and engaging. Chris is credited with finding good snorkeling spots and helping a family of eight see a wide range of marine life. Hillary is praised for explaining landmarks, sharing island history, and setting a schedule around each group’s pace.

That variety matters because a private boat day is only as good as the person driving it. The captain decides where to stop, helps you understand local conditions, and manages the timing between snorkeling and lunch.

You can improve the day by being clear at the start. Tell the captain who wants to snorkel, who prefers beaches, whether children are comfortable in the water, and how much time you want for lunch. The more specific you are, the easier it is to build a route that suits everyone.

Who should book this St. Thomas charter?

This is a strong fit for families, couples traveling together, and groups of friends who want a private day rather than a standard sightseeing cruise. It is especially good for groups with mixed interests because you can combine snorkeling, swimming, beach time, drinks, and lunch.

It also suits people who want to see several areas around St. John without arranging separate transportation. The boat gives you access to Lovango Cay, Honeymoon Beach, Maho Bay, and Christmas Cove in one long outing, subject to weather and the captain’s judgment.

I would be more cautious if your group has no interest in snorkeling, swimming, or spending most of the day on a boat. The price is hard to justify for someone who wants only a quick scenic ride. I would also think twice if your group is very small and cost matters more than privacy.

Children count toward the total capacity regardless of age. Service animals are allowed, and most people can participate. The charter requires good weather. If poor conditions cancel the outing, you can choose another date or receive a full refund. Cancellations made at least 24 hours before the start time also qualify for a full refund, while later cancellations and changes are not accepted.

Should you book it?

Book this charter if you can fill at least six seats and want a flexible day built around your group. The best reasons are the private boat, easy water access, sea turtle snorkeling at Maho Bay, and the chance to finish with Pizza Pi, Lime Out, or another local lunch choice.

Before paying, add $160 to $240 for likely fuel, include an 18 to 20 percent captain’s gratuity in your budget, and ask about current bow-net condition. If your group agrees on a water-focused day and values a captain who can adjust the route, this is one of the more practical ways to explore St. Thomas, St. John, and the nearby cays in a single outing.
