Private Full Day Guided Snorkeling or Diving Charter in St Thomas

The best part of this St. Thomas charter is control. You get a private 42-foot boat, a captain who can adjust the route, and a full day to seek out reefs, turtles, rays, fish, or the Cartanza wreck at Buck Island. Guides such as Stephanie, Abby, Wolfgang, and Nen have led outings with a friendly, hands-on approach.

I like the one-group-only format and the chance to spend real time in the water instead of rushing through a packed boat schedule. I also like the practical extras: fitted masks and fins, flotation gear, snacks, soft drinks, water, and Pirate Punch for adults 18 and older.

The main drawback is cost. At $3,225 per group, this only makes sense if your party can share the expense and wants a private day rather than a cheaper shared excursion. The published rate says up to one group, so confirm the exact party pricing before booking.

Key points to know before you book

• Four possible water stops: Buck Island, Secret Harbour, Little St. James, and Christmas Cove can be combined into a long day on the water.
• The route is flexible: Talk with the captain about your priorities, then adjust stops for conditions, swimming ability, and interest in snorkeling or scuba.
• Buck Island brings variety: The Cartanza wreck and two separate snorkeling areas offer more than a single reef stop.
• The crew works with beginners: One-on-one help has been provided for first-time snorkelers, while experienced scuba participants can focus on visibility and marine life.
• Lunch is not included: Secret Harbour may offer a shore lunch, but you must swim or float from the boat to the beach.
• This is an active water day: Everyone must be able to swim comfortably and capably in open water without assistance.

Why a private St. Thomas charter can be worth the price

A private boat changes the rhythm of a day at sea. You are not locked into a fixed list of stops or waiting for a large group to finish. You can tell the captain if you want more time with turtles, a calmer cove, a wreck site, or a second look at a reef.

That flexibility matters in the Virgin Islands because wind and sea conditions can affect which side of an island feels best. The crew can suggest alternatives rather than forcing the original plan. Anna and Wolfgang, for example, have steered groups toward sites with better conditions and fewer boats.

The listed price is $3,225 per group, with the listing describing the rate as up to one group. That wording deserves a quick check before you pay, especially if you have a large family or several friends. For a full day on a private 42-foot boat, the value improves when several people split the charge.

This is not the right pick if you only want a quick hour in the water. It is better suited to a group that wants six to eight hours outside, with transportation between several sites, time for snacks and lunch, and a captain focused only on your party.

Starting at Saga Haven Marina at 8:30 a.m.

Plan to arrive 30 minutes before the activity time at Aqua Marine Dive Center, 6117 Estate Frydenhoj, Saga Haven Marina, St. Thomas. The marina is the starting and ending point, and transportation to the dock is not included.

At check-in, you complete the required paperwork, meet the crew, and get fitted for your equipment. The supplied gear includes a mask, fins, snorkel, and flotation device. A certified snorkel guide and USCG-licensed captain are included, which is useful if your group has mixed ability levels.

The early start gives you a full day on the water, but it also means you should plan your morning carefully. Bring anything you personally need for a long day outside, since the included food is limited to snacks such as cookies, crackers, and chips. Water and soft drinks are supplied.

The boat is described as eco-friendly and 42 feet long. That gives your group a private base between stops, with room to relax, eat a snack, and talk with the crew about the next site. Exact seating and onboard facilities are not specified, so ask Aqua Marine Dive Center any practical questions before departure.

Buck Island and the Cartanza wreck

The first major stop is Little Buck Island, also referred to as Buck Island. The cruise there is part of the experience. The crew shares information about the area’s geography and local past while you settle into the boat and get ready for the water.

Buck Island offers two different snorkeling areas. One is Shipwreck Cove, where you can see the Cartanza wreck. A wreck gives you a different view from a standard reef. Instead of only looking for fish around coral, you can examine how marine life gathers around a man-made structure underwater.

The other Buck Island area provides a separate setting for snorkeling. Conditions determine exactly how the stop works, so the captain may shape the timing around water and weather. The scheduled stop is about three hours, making this the longest part of the day and a good place to settle into the water rather than rush.

If you are new to snorkeling, ask for help with the mask before you swim far from the boat. Abby has provided one-on-one guidance for a first-time snorkeler, and the crew has also helped children select properly fitting masks and fins. That sort of attention is more useful than fancy equipment. A leaking mask can spoil an otherwise fine morning.

Experienced scuba participants can also use the day for underwater exploration, but the activity requires every participant to be comfortable and capable in open water without assistance. Children must be at least five and accompanied by an adult at all times.

Secret Harbour for a possible lunch break

Secret Harbour is usually considered a lunch stop. The boat gets as close to shore as possible, but you need to swim or float to the beach if you want to eat at the restaurant.

That detail is important. Lunch is not included in the charter, and reaching the restaurant is not a simple walk off the boat. If someone in your group is not comfortable with an open-water swim, discuss the plan with the captain before making Secret Harbour your lunch stop.

The one-hour timing gives you a change of pace after the longer Buck Island session. You can stretch your legs on shore, eat at the restaurant if you choose, or remain with the boat. Since meals are not supplied, bring money for lunch and allow for the time it takes to get between boat and beach.

The stop also shows the tradeoff of a flexible charter. You get choices, but you are responsible for deciding how much time to spend eating versus staying in the water. A group that wants every minute for snorkeling may prefer a quick snack onboard.

Little St. James and protected marine water

The Ledges of Little St. James are reached by a short ride. The area is described as a protected marine park with hard and soft coral. It is a good stop for anyone who enjoys watching fish move through coral formations rather than focusing only on a wreck.

Look for schools of bluestriped grunts and blue tangs. The crew may point out fish you would otherwise swim past, and the water time can feel more personal because the boat is reserved for your group.

Little St. James is also an unusual place geographically. The island is privately owned and has a public reputation that may attract attention, but the useful reason to stop here is the protected marine setting. Your time is spent in the water, not on the island, and the charter does not present a shore visit as part of the plan.

As with every stop, conditions matter. The captain may alter the sequence or choose another site. That is one reason to treat the itinerary as a suggested route, not a promise that every listed location will be visited in a fixed order.

Christmas Cove and the search for sea life

Christmas Cove, near Greater St. James, can be visited before or after lunch. The scheduled time is about two hours, giving you another substantial water session rather than a quick photo stop.

The cove is a promising place to look for spotted trunkfish, French angelfish, southern stingrays, and larger fish. Sea turtles are a major draw on this charter, and several outings have included large turtles. Other possible sightings have included barracudas, dolphins, and even a nurse shark, but wildlife is never guaranteed.

That uncertainty is part of the deal. You are paying for access, time, a crew, and the chance to search good areas, not for a fixed list of animals. A good guide can help you notice smaller fish and understand what you are seeing, but no captain can order a turtle to appear.

Christmas Cove is also a comfortable place to slow down. After several hours of moving between sites, you can use the time for a relaxed swim, a float, or another guided look at the reef. Ask the crew what they are seeing before entering the water, especially if your group includes first-time snorkelers.

What the crew adds to the day

The strongest feature of this charter is the crew’s role in making the day work for different people. Names associated with past outings include captains Steve, Justin, Tommy, Dave, and Wolfgang, along with guides such as Stephanie, Abby, Erika, Jess, Nen, and Ryan.

You should not assume a particular person will be onboard, but the range of roles is useful to understand. The crew handles equipment, explains the water sites, gives safety direction, and can spend time with less confident swimmers. Nen has been described as especially strong at identifying ocean life and explaining what is around you.

The captain also manages the practical side of the trip. If the water is rough at one location, the group can discuss another option. If your party includes two scuba participants, several snorkelers, and people who prefer to stay on the boat, tell the crew early. The boat’s private setup makes that kind of mixed day easier to manage than a rigid group excursion.

The included Pirate Punch is available to adults 18 and older. It is a pleasant extra, but remember that alcohol and open water do not mix well for everyone. Use your judgment, particularly if you plan to snorkel again later in the day.

Gear, food, and what you still need to arrange

The charter supplies a mask, fins, snorkel, and flotation device. Water, soft drinks, cookies, crackers, and chips are also included. That covers basic comfort, but it is not a full meal.

You need to arrange your own transportation to Saga Haven Marina. The activity ends back at the same meeting point, so plan your return from the marina rather than assuming a hotel transfer is part of the price.

Bring practical personal items for a long day outside, but keep your packing simple. You will want sun protection, swimwear, and anything you need to feel comfortable between water stops. The provided information does not specify towel service, storage, or changing facilities, so confirm those details with the operator.

Service animals are allowed, and the activity is near public transportation. Most people can participate, but the open-water requirement is firm. Children must be accompanied by an adult, and the minimum age is five.

Who will enjoy this charter most

I would choose this for a family or friend group that values privacy and wants several hours at sea. It is especially suitable when some people want snorkeling, others want scuba, and everyone wants to share the same boat and route.

It also suits experienced snorkelers who want more time at each site. The day includes enough scheduled water time at Buck Island and Christmas Cove to avoid the rushed feeling of a short excursion.

First-time snorkelers can do well here if they swim comfortably and ask for help early. The crew has worked with people trying snorkeling for the first time, including one-on-one support. Still, this is not a lesson in a swimming pool. You must be capable in open water without assistance.

I would think twice if your party dislikes boats, cannot swim, needs a fully catered lunch, or wants guaranteed turtle sightings. I would also compare the cost against a shared trip if privacy is not a priority.

Booking, weather, and cancellation details

The activity requires good weather. If poor weather forces a cancellation, you are offered another date or a full refund.

If you cancel for your own reasons or ask to change the booking, the payment is non-refundable and cannot be amended. Because of that strict policy, confirm your party size, meeting point, swimming ability, and preferred activity before booking.

The tour is private, and confirmation is provided at booking. Contact Aqua Marine Dive Center in advance if anyone in your group has special requirements or if you need clarification about the scuba option, lunch arrangements, or the published group pricing.

Should you book this St. Thomas charter?

Book it if you want a private boat, a long day, several possible reef stops, and a crew that can adapt the outing to your group. The Cartanza wreck, Little St. James coral, Christmas Cove wildlife, and possible turtle sightings give the day plenty of variety.

Skip it if you are watching every dollar or only want a brief snorkel. The price is high, but it can be reasonable when divided among a group that will use the boat for six to eight hours.

My practical advice is to contact the operator before paying and confirm the number of people covered by the $3,225 rate. If that price works for your party, this is a strong choice for a private St. Thomas water day with real flexibility and plenty of time in the sea.
