Private Luxury Charter Aboard New Multi-Deck Lagoon Catamaran
The best part of this St. Thomas charter is control. Your group gets a private catamaran, a captain-planned route, and room to choose between reef snorkeling, turtle sightings, swimming, and a white-sand beach stop. A maximum of 12 people keeps the day from feeling like a floating bus.
I like the new Lagoon 420 multi-deck boat, with shaded seating, sun decks, lounge nets, a swim platform, and a restroom. I also like the crew’s local touch. Captains such as Hillary, Vic, Mike, and Alex add island history and help first-time snorkelers get comfortable.
The main thing to weigh is the weather. Rain, wind, waves, or murky water can change the snorkeling, and one outing was reported as more boat ride than reef time after several days of rain. The boat and crew may be excellent, but nature sets the schedule underwater.
Key Points Before You Book

- Private boat for up to 12: Your group does not share the catamaran with strangers.
- Departing from Havensight: Meet Seas the Day Charters and Tours at WICO/Havensight in Charlotte Amalie.
- Snorkeling gear and drinks included: Equipment, water, soda, beer, and rum punch are provided.
- Sea turtles are a real possibility: Maho Bay, Buck Island, and nearby cays may offer turtle sightings, along with rays, squid, and tropical fish.
- Flexible island route: Your captain may visit St. John, Water Island, St. James, Lindbergh Bay, Brewers Bay, Honeymoon Beach, or nearby reefs.
- Plan for about seven hours: The experience returns to the same meeting point, with shorter half-day options also described.
A Private Lagoon Catamaran From Havensight
This is a full-day sailing outing from Charlotte Amalie, not a fixed sightseeing cruise with every minute locked in. You meet at Seas the Day Charters and Tours in the WICO/Havensight area, then board a new Lagoon 420 multi-deck catamaran, or a comparable vessel if needed.
The boat matters here. A Lagoon 420 gives you several ways to spend the day. You can sit under cover, stretch out in the sun, use the forward nets, or move to the swim platform when it is time to enter the water. A clean restroom on board is another small but important comfort during a seven-hour trip.
The maximum is 12 people, and the charter is private, so your group controls the mood. You can keep the day active with several water stops, or spend more time swimming and relaxing at one beach. This setup works especially well for families, couples traveling with friends, birthday groups, and anyone who does not want to follow a large tour boat from one stop to the next.
The listed price is $1,615.50 per group. With 12 people, that works out to about $135 per person before the crew tip, a fair price for a private boat, captain, snorkeling equipment, drinks, and several hours on the water. With only two or four people, the per-person cost rises quickly. I would consider this strongest value when you can fill most of the boat.

Your Captain Helps Shape the Route

The crew works with you ahead of time on an itinerary. That does not mean every destination is guaranteed. Wind, rain, sea conditions, marine traffic, and the captain’s judgment can affect the route, but you have more say than you would on a standard shared excursion.
The company has several captains who receive frequent praise for their island knowledge and easy manner. Hillary is especially good at helping uncertain swimmers become successful snorkelers. Vic adds local facts and has a knack for spotting turtles. Mike is noted for explaining the areas around St. John and finding strong snorkeling locations.
Alex has also handled trips when staffing was tight, working hard to keep the day moving. Other named crew members include Wallens, Pogan, Aaron, Caroline, Jason, Hope, Osay, and Vali. The exact captain depends on scheduling, so book this for the boat and format rather than for one particular person unless the company confirms that request.
One useful detail is the crew’s willingness to offer help in the water. That matters if someone in your group is new to snorkeling. The experience is not only for confident swimmers, though you should still be comfortable entering the sea and following crew instructions.
Reef Snorkeling Near St. Thomas and St. John

The snorkeling portion is the heart of the trip. Possible areas include Buck Island, St. James, Water Island, reefs near St. John, Maho Bay, and Lovango Cay. The route depends on conditions and the plan you make with your captain.
A typical day may use one stop for coral and tropical fish, then another for sea turtles. Maho Bay in the national park area has been used for turtle sightings, while locations near Lovango Cay can provide reef scenery and schools of fish. You might also see rays, stingrays, and Caribbean reef squid. These are not guaranteed, but the variety is part of what makes a private route worthwhile.
You receive snorkeling equipment, and several outings have found the gear to be in good condition. The boat’s swim platform makes getting in and out easier than climbing over a high side. You can take your time at the reef rather than being rushed through a short photo stop.
Still, keep your expectations practical. Clear water is never guaranteed. After several rainy days, one trip had poor visibility and offered less snorkeling than expected. Waves can also make it harder to watch turtles, even when the animals are present. I would book this for the chance to see marine life, not as a promise of a perfect underwater aquarium.
If you are a first-time snorkeler, tell the crew early. Hillary and other captains have helped hesitant swimmers get comfortable, and the smaller group makes it easier to ask for assistance. If your entire group wants a serious reef day, say so when discussing the itinerary.
Turtles, Rays, Fish, and the Surprise of Squid

Sea turtles are the most talked-about wildlife highlight, and several routes have produced close encounters. You may find them near turtle-friendly bays, moving calmly through the shallows while swimmers watch from a respectful distance.
Rays and stingrays also appear, along with tropical fish around the coral. One especially fortunate group saw Caribbean reef squid, a memorable sight that can turn a good snorkel into a story you keep telling. None of these animals can be scheduled, so the captain’s skill in reading conditions and choosing locations is important.
The crew also points out what you are seeing. That makes the stop more rewarding than simply swimming over coral without context. You get a better sense of the islands’ sea life and why protecting the reefs matters.
Follow the crew’s instructions around wildlife. Do not chase turtles or touch animals. The calmer you are, the better your chance of watching them behave naturally.

A Beach Stop at Honeymoon Beach or Beyond

After snorkeling, the boat may head toward Honeymoon Beach on Water Island, Lindbergh Bay, or Brewers Bay. These stops change the rhythm of the day. After swimming with a mask and fins, you can walk on white sand, sit in shallow blue water, play beach games, or simply cool off.
Honeymoon Beach is a popular choice because it combines an attractive beach with easy swimming. You may also have the chance to visit Dinghy’s Beach Cafe, where Pain Killers are available, or LimeOut, the floating taco bar. These food and drink stops are not the main event, and access depends on the route and conditions, but they can add a distinctly island-style finish.
Some outings instead visit St. John and Cruz Bay or stop at multiple coves. If there is one beach you especially want to see, make that clear before departure. A private charter gives you a better chance of shaping the plan, but the captain still has to balance distance, sea conditions, and the time needed to return to Havensight.
One past outing did not reach Honeymoon Beach, despite that being a hoped-for stop. That is a useful reminder to treat the itinerary as flexible. Ask what is realistic on your date rather than assuming every beach, reef, and floating bar can fit into one day.
Drinks, Shade, and Life Between Stops

The time between snorkeling spots is part of the experience. Water, soda, beer, and the company’s rum punch are included, so you do not have to pack a cooler for basic refreshments. The cold drinks are especially welcome after swimming in the sun.
The catamaran offers both shade and open-air seating. I like having that choice because the Caribbean sun can feel wonderful at first and tiring later. Use the covered areas when you need a break, then move to the nets or upper deck for views and breeze.
Bring your own sunscreen and towels. That is easy to overlook when drinks and snorkeling gear are included. You should also plan to tip the captain and crew if they provide good service. The customary amount is 15 to 20 percent, which can be a meaningful addition to the cost of a private charter.
The rum punch is part of the fun, but pace yourself. Seven hours on a moving boat, with sun and swimming, can catch up with you. Alternate alcoholic drinks with water and eat something before boarding.
How the Seven Hours Usually Feel

The advertised duration is about seven hours, though the experience description also refers to half-day outings. Confirm the exact length when booking, particularly if you are fitting this around a cruise departure or another St. Thomas activity.
A full day gives you time for a sail, one or more snorkeling sites, a beach stop, and a relaxed return. The best days do not feel like a race. You have time to swim, dry off, enjoy a drink, and listen as the captain points out islands and landmarks.
A half-day option may suit couples or families who want snorkeling without spending an entire day on the water. It can also be a better fit if someone in your group gets tired, sunburned, or seasick. The tradeoff is less time for multiple reefs and beaches.
The tour returns to the Havensight meeting point. Arrange your onward transportation with care, especially if you are visiting from a cruise ship. One outing had a late return, and another involved confusion with taxis after being dropped at a resort area. Build in extra time and confirm where you will be collected after the boat ride.
What the Price Really Buys You

At $1,615.50 per group of up to 12, you are paying for privacy more than for a luxury meal or a long list of included activities. The boat, captain, crew, snorkeling equipment, restroom, and drinks are covered. You are not paying for towels, sunscreen, food, or the crew tip.
For a full group, the math works well. You get a private seven-hour boat day for roughly the cost of several individual excursions, while keeping control of the route and avoiding an overcrowded vessel. For a small group, the same price may feel steep unless privacy and flexibility are your top priorities.
The boat itself adds value. Multiple decks, shade, lounge nets, and a swim platform make a long day more comfortable. If your main goal is simply to reach one snorkeling site for an hour, a cheaper shared trip may be enough. If you want a private island day with drinks, beach time, and room to adjust the plan, this charter makes more sense.
Who Will Enjoy This Charter Most
I would recommend this outing to a group that wants to spend real time on the water and can agree on a general plan. Families benefit from the private setting, especially when children need breaks between snorkeling stops. Friends can spread out, play music, swim, and decide how active the day should be.
It also suits first-time snorkelers because the crew can offer personal help. Confident swimmers will appreciate having longer at the reefs and the possibility of visiting several locations.
This is less suitable if you need a guaranteed beach, a guaranteed turtle sighting, or a tightly timed return. It is also not ideal for anyone who dislikes sun, wind, boat motion, or changing plans. Poor weather can cancel the trip, in which case you receive a different date or a full refund.
Free cancellation is available up to 24 hours before the start time. Changes made within 24 hours are not accepted, and a weather cancellation is handled with a new date or full refund.
Should You Book the Seas the Day Charter?
Book it if you can fill the boat, want privacy, and care about combining snorkeling with beach time. The strongest features are the small private group, comfortable Lagoon catamaran, helpful captains, included drinks, and real chances to see turtles, rays, tropical fish, and even squid.
Before booking, tell the company which matters most: reef snorkeling, turtle sightings, St. John, Honeymoon Beach, or a relaxed sail. Bring sunscreen and towels, budget for the tip, and leave room in your schedule in case the boat returns late.
I would not choose it for a guaranteed wildlife show. I would choose it for a flexible day in the Virgin Islands, with a good boat, a local captain, and enough time to enjoy the water at your own pace.
