Private Luxury Catamaran Half Day Charter
The best part of this private catamaran charter is control. You are not following a packed boat on someone else’s schedule. Your group can request pickup changes, adjust the route, and choose how to spend time on the water. Captain Joe and Katie handle the boat, snorkeling, drinks, and the small details.
I like the generous space created by limiting the boat to 12 people, even though it is certified for more. I also like the two-part plan: guided turtle snorkeling at Buck Island National Wildlife Refuge, followed by a slower beach stop at Honeymoon Beach. The main tradeoff is time. Four hours goes quickly, especially if your group wants a long snorkel, a beach visit, and plenty of cruising.
Key points at a glance
- Turtle Cove snorkeling: Swim with green sea turtles, colorful fish, and coral at Buck Island National Wildlife Refuge.
- Two capable hosts: Captain Joe brings island experience, while Katie guides the snorkel and tends the bar.
- Private use for up to 12: Your group does not share the catamaran with strangers.
- A flexible itinerary: Request special celebrations, alternate pickup points, or changes to the day’s plan.
- Comfort on board: Expect a custom swim ladder, aft swim platform, fresh-water rinse, and a modern bathroom.
- Four hours with an open bar: Snacks and unlimited top-shelf drinks are served after the in-water activities.
A private boat day from Yacht Haven Grande

Someday Charters starts at 5304 Yacht Haven Grande in Charlotte Amalie. The activity also ends there, which keeps the plan simple. You do not need to arrange a separate return from a distant beach or snorkeling site.
The setting is suited to a private outing. Instead of waiting for a large group to board, you step onto a power catamaran reserved for your own party. The boat has a wide aft swim platform and a custom-built ladder, so getting into and out of the water should be less awkward than climbing over a narrow side rail.
I like this setup for families and mixed-age groups. Strong swimmers can get in quickly, while anyone who prefers to remain on board has room to sit, use the bathroom, or enjoy the views. The crew also provides a fresh-water rinse after snorkeling, a small feature that matters when salt water, sunscreen, and wet swimwear begin to wear on you.
The boat is certified for up to 26 people, but Someday Charters limits private trips to 12. That choice gives your party more room to move and makes it easier to speak with the crew. You also avoid the usual problem of a crowded excursion where every decision requires a vote among strangers.

The ride along St. Thomas’s southern coast
The outing begins with a ride along the picturesque southern coast of St. Thomas. The power catamaran adds a sense of motion to the trip, rather than simply serving as a floating platform between stops.
That ride is part of the appeal, but it also uses some of your four-hour window. If you want the longest possible time in the water, tell the crew early. If your group enjoys the boat ride itself, you can treat the transit as part of the day rather than lost time.
The itinerary is described as customizable. The office staff can organize special requests, alternate pickup locations, itineraries, and celebrations. The exact route still depends on conditions and the captain’s judgment, but the private format gives you room to explain what matters most before departure.
For some groups, that may mean more time snorkeling. For others, it may mean a relaxed pace, a birthday toast, or extra time near the beach. The useful point is to discuss priorities before the boat leaves, since four hours is enough for two well-chosen stops but not an unlimited list of activities.
Turtle Cove and the green sea turtles

The first main stop is Turtle Cove at Buck Island National Wildlife Refuge. Here, a professional snorkel guide provides instruction on using the supplied equipment and then leads you along the surface.
The marine life is the star. You can expect to swim among green sea turtles, colorful fish, and coral reefs. The guide’s role matters because a good escort helps you notice more than you would on your own. You are not simply handed a mask and pointed toward the water. Katie is identified as the snorkel guide, and her work in the water is paired with bartending later in the trip.
You should have a moderate level of physical fitness for this experience. Snorkeling requires comfort in the water, the ability to use the ladder, and enough stamina to remain active during the stop. Medical concerns should be discussed with your own medical professional, and you should tell the captain about allergies or medical conditions before the activity begins.
The supplied snorkeling gear is sanitized and included in the price. That saves you from packing a mask, fins, and related equipment, though you may still want to bring personal swimwear and any familiar gear you prefer. The information provided does not specify the exact gear sizes or brands, so ask the operator if that matters to you.
The wildlife setting also calls for restraint. The experience is built around observing turtles and reef life, not touching or chasing them. Your guide can help keep the encounter orderly and informative while protecting the animals and the reef.
A snack and top-shelf drinks after the water

After the snorkeling stop, you return to the boat for snacks and drinks. The open bar is unlimited, but it is available after the in-water activities. That order makes sense. You can focus on swimming first, then settle into the social part of the outing once you are dry.
Katie serves as both snorkel guide and bartender, according to the available details. That combination can be useful on a private charter because the same crew member helps with both the active and relaxed parts of the day. Captain Joe handles the boat and brings experience with the islands, while the two-person team keeps the outing personal.
The food is described as snacks rather than a full meal. Plan accordingly. If your group needs a substantial lunch, ask what snacks are being served and make any special request before departure. The office staff handles requests, but the supplied information does not promise a specific menu or dietary accommodation.
The top-shelf bar is a meaningful part of the value for adults who want a celebratory afternoon. It is less important if your group does not drink, since the main benefits remain the private boat, crew, snorkeling guide, and two-stop itinerary. You can also enjoy the setting without treating the bar as the center of the trip.

Honeymoon Beach on Water Island

The second stop is Honeymoon Beach on Water Island. After the activity at Turtle Cove, the boat moves on to a gentler setting where you can catch the sun from the catamaran, use the floats, or go ashore and relax on the warm sand.
This change of pace is smart. Turtle Cove provides the active wildlife encounter, while Honeymoon Beach gives you time to stretch out and decide how much energy you have left. Some people will prefer the boat and floats. Others will want the feel of sand underfoot and a quiet beach break.
The beach stop is also where the private format pays off. Your party can choose how long to linger within the limits of the four-hour charter. On a shared trip, you would likely have to return when the schedule says so, even if half the group wants more beach time and the other half wants to keep cruising.
Still, two stops require realistic expectations. You may not have enough time for a lengthy snorkel, an extended beach visit, a full meal, and a leisurely cruise. I would decide in advance which part matters most to your group. If turtles are the priority, protect time at Turtle Cove. If this is mainly a social afternoon, spend less time in the water and enjoy Honeymoon Beach and the boat.
What the $1,495 price really covers

The charter costs $1,495 per group of up to 12 people. That works out to about $125 per person if you fill every place, before gratuity. For a smaller group of four, the effective price is about $374 per person, so the value changes sharply with group size.
The price includes the boat, fuel, professional crew, snorkeling equipment, a guide, snacks, and unlimited drinks after the water activities. It also includes comforts that are easy to overlook until you need them: a working bathroom, fresh-water rinse, swim platform, and boarding ladder.
I see the strongest value for a full family group, a group of friends, or a celebration where privacy matters. Twelve people sharing the cost can make a private boat reasonable compared with purchasing individual seats on several separate activities, though exact comparisons depend on the alternatives available during your visit.
For two or three people, the charter is a luxury purchase. You are paying for space, flexibility, and personal service rather than the lowest possible cost. That can still be worthwhile for a birthday, anniversary, or special day on St. Thomas, but a shared boat would likely cost less if your main goal is simply reaching a snorkeling site.
Customary gratuities are not included. Keep that separate from your budget. The crew’s ability to adapt the outing is one of the main reasons to consider this charter, so plan for a tip if the service meets your expectations.
Who will get the most from this charter

I would recommend this experience to people who value privacy more than a fixed bargain price. It suits a family that wants different activity levels, a group of friends looking for a social day, or anyone marking a special occasion.
It also works well for a group with mixed preferences. One person can snorkel, another can relax on the boat, and others can head toward the beach at Honeymoon Beach. The private setting makes those differences easier to manage.
You should be reasonably comfortable with physical activity and the water. The operator asks for a moderate fitness level, and the plan includes snorkeling and boarding by ladder. Service animals are allowed, and the meeting point is near public transportation, which may help with access to Yacht Haven Grande.
I would think twice if your group wants a full-day sailing trip, a large meal, or several widely separated islands. The charter lasts about four hours and focuses on two sites. Its strength is a compact, private half-day rather than a long expedition.
Booking early and handling the weather

This experience is booked, on average, 318 days in advance. That is a strong signal to reserve early, especially if you have fixed cruise dates, a family gathering, or a celebration that cannot easily move.
Confirmation is provided at booking, and the ticket is mobile. The activity requires good weather. If poor conditions lead to cancellation, you can choose another date or receive a full refund.
You can cancel for a full refund up to 24 hours before the start time. Changes or cancellations made less than 24 hours ahead are not accepted for a refund, and the cut-off follows local time. Build in a little care when planning around flights, cruise departure, or other fixed commitments.
The office staff can help with alternate pickup points and special requests. Share important details early, including allergies, medical conditions, and celebration plans. Captain Joe and Katie can only tailor the day well if they know what your group needs before the boat leaves.
Should you book the Someday Charters catamaran?

Book it if you have a group large enough to share the cost and want a private, flexible day rather than a basic boat transfer. Turtle Cove supplies the wildlife and snorkeling, while Honeymoon Beach offers a relaxed finish. The crew pairing of Captain Joe and Katie adds a personal touch, with island experience at the helm and hands-on help in the water and at the bar.
Skip it if you are traveling alone, on a tight budget, or seeking a full-day island-hopping trip. Four hours is short, and the $1,495 group price makes the most sense when privacy, comfort, and control are central to your plans.
For the best value, bring a group close to the 12-person limit, decide whether snorkeling or beach time matters more, and tell the office about special needs before the day begins. That turns a good half-day boat trip into one shaped around your own priorities.
