SeaFari FastCat – Sun, Fun, Swimming, Snorkeling & Boat Party
A 1,000-horsepower catamaran, two quiet beach stops, open-water snorkeling, and rum punch make this a lively way to spend four hours in St. Thomas. The SeaFari FastCat is less a sightseeing cruise than a moving beach party with a strong dose of speed.
I like the variety: you can snorkel, swim, float, paddleboard, play pickleball, or simply sit with a drink. I also like the crew service. Keith contacts you before the trip, and Victor and Ashley lead the boat with facts, humor, and practical help.
The main consideration is the snorkeling. It happens directly from the boat in open water, so this is not the best choice if you need calm, shallow water or have medical concerns affected by swimming, waves, wind, or current.
SeaFari FastCat at a Glance

- The 1000-horsepower Breeze turns the ride itself into part of the attraction, with a fast run from Charlotte Amalie around Water Island.
- Honeymoon Beach and Limestone Beach each receive about an hour for swimming, snorkeling, and relaxing.
- Snorkel gear, floats, paddleboards, rum drinks, and beer are included in the $89 price.
- Open-water snorkeling may bring you near green sea turtles and colorful fish, but sea conditions can affect comfort.
- Keith, Victor, and Ashley add personal service, trip information, and humor to the outing.
- The trip suits active families and social adults, but age, height, weight, fitness, and health rules matter.
Leaving Yacht Haven Grande on the Breeze

Your morning begins at 9:30 a.m. at R Bar in Yacht Haven Grande, at 5316 Yacht Haven Grande, Suite S-104, Unit 61. The tour returns to this same meeting point after about four hours, so it fits neatly into a cruise-port day or a free morning in Charlotte Amalie.
The boat is the 1000-horsepower Breeze, a power catamaran built to make the route feel quick and energetic. You are not simply carried from one beach to another. The turbo-powered run out of the harbor is part of the entertainment, with views toward Water Island, Charlotte Amalie harbor, Elephant Bay, Frenchman’s Cut, and the waterfront.
I like this opening because it gives you a sense of St. Thomas from the water before the swimming begins. You get a look at the harbor’s working side and waterfront activity, then move toward quieter coves and beaches.
The fast ride can be exciting, but it may not suit everyone. If you prefer a slow, quiet boat trip, this is the wrong mood. The experience is built around music, movement, social energy, and time in the water.
The boat has restrooms and safety equipment. Parking is available at the meeting point, and the location is near public transportation. Private transportation is not included, so you need to arrange your own way to and from Yacht Haven Grande.

The First Hour at Honeymoon Beach

Honeymoon Beach is one of the two main stops, with about an hour for swimming, snorkeling, and floating. You can use the provided flotation devices and snorkel equipment, then take a break at the beach bar and restaurant.
This stop works well as an easy introduction to the water. You can start with a swim, try snorkeling, or stay dry and enjoy the scenery. The included gear means you do not need to pack your own mask, snorkel, or fins, although bringing personal equipment is still reasonable if you prefer a particular fit.
The beach stop is also useful for people in the group who do not want to snorkel. One person can swim while another relaxes, uses a float, or enjoys the bar and restaurant. That flexibility keeps the outing from becoming a single-activity trip.
Keep your expectations practical. The stop lasts about an hour, not half a day, so you will not have unlimited time to settle in. The tour has a schedule to keep, and the boat needs to reach its second beach stop before returning to St. Thomas.
Snorkeling Directly From the Boat

Snorkeling is done directly off the boat in open water. That detail matters more than the cheerful list of equipment and drinks. You will need to enter the sea from the vessel, manage a mask and snorkel, and feel comfortable swimming in conditions that can include wind, waves, or current.
The water may offer views of colorful fish and green sea turtles. Wildlife sightings are never guaranteed, but the possibility adds real appeal for anyone who enjoys seeing marine life rather than only looking at the shoreline.
The crew provides modern masks, snorkels, and fins, along with safety equipment and guidance. Still, equipment cannot remove the basic demands of open-water swimming. You should consider your fitness and medical history carefully if you have asthma, diabetes, epilepsy, a cardiac condition, a respiratory condition, or another health issue.
The listed age range is 5 to 80 years, with a minimum height of 36 inches and a maximum weight of 275 pounds. These are participation limits, not a promise that every person within them will find the water easy. Children must also be comfortable around a boat, in open water, and with the physical effort of swimming.
Limestone Beach and a Second Chance to Swim

Limestone Beach is the second major stop, also with about an hour for swimming, snorkeling, and flotation devices. Having two stops is one of the strongest parts of the tour. If you are slow to get comfortable in the water at Honeymoon Beach, you have another chance later.
The two-stop design also breaks up the boat ride. You are not asked to spend four straight hours on a moving vessel or at one beach. The changing scenery keeps the outing active, while the hour at each beach gives you enough time to swim without turning the day into a rushed photo stop.
You may use floats and paddleboards here, depending on availability and the group’s flow. Pickleball is also listed among the available activities, which gives the trip a playful edge beyond standard snorkeling.
The tradeoff is that an hour passes quickly. If you want long, unhurried snorkeling sessions, a dedicated snorkel charter may serve you better. SeaFari is designed for variety: a little riding, a little beach time, a little swimming, and a little social time.

Drinks, Gear, and the Social Mood

Rum drinks, rum punch, and beer are included throughout the tour. Snorkel gear, floats, and paddleboards are also included, which makes the $89 price easier to assess. You are paying for the boat, crew, beach access, equipment, and drinks in one package rather than adding each item separately.
The drink service helps shape the atmosphere. On the way back, the boat takes on a Caribbean party feel, and you can mingle with people from different places while looking back toward St. Thomas. If you enjoy meeting others on an excursion, this setup should feel natural.
It is less suitable if you want a private, quiet charter. The boat can carry up to 80 people, so the social character is part of the product. Even with a smaller group on a particular departure, you should expect a shared activity rather than personal service in a small-boat setting.
Dinghy’s Beach Bar adds a local touch, with the chance to interact with people connected to the island’s beach culture. The stop is not presented as a formal cultural program, but it gives you a more grounded moment than simply looking at the coast from offshore.
Crew Service and Helpful Communication

The human side of this experience gets important attention. Keith, the manager, communicates before the excursion with details and calls on the morning of the trip to confirm the reservation. That is useful in St. Thomas, where meeting points and timing matter, especially if you are fitting an excursion between other plans.
Victor and Ashley lead the outing. They share facts about the area, help with the activities, and bring some humor to the ride. I value that combination because a boat tour can feel mechanical if the crew only points out landmarks and handles equipment.
The service also appears accommodating, which matters when a group includes different comfort levels in the water. Still, the crew cannot change the basic nature of the trip. You need to be ready for an active morning, open-water entry, and a boat environment shared with other people.
Is $89 a Fair Price?

At $89 per person, the tour offers solid value if you plan to use the included features. The price covers about four hours aboard the power catamaran, two beach stops, snorkel equipment, floats, paddleboards, rum drinks, beer, safety gear, crew guidance, and restrooms.
That is a better deal for an active participant than for someone who plans to sit aboard and skip the water. If you snorkel, swim, use a float, enjoy a drink, and appreciate the fast boat ride, several parts of the package work in your favor.
You should also count the convenience of not arranging separate beach transportation, equipment rental, and a boat trip. Private transportation to the meeting point is not included, but parking is available and public transportation is nearby.
The value is weaker if you want a small group, a quiet cruise, or a long snorkeling session in one location. For those priorities, the larger shared boat and scheduled one-hour stops may feel limiting.
Who Will Enjoy This Four-Hour Trip?

I would recommend SeaFari FastCat to you if you want several activities in one morning. It is a good match for active families, couples, friends, and solo visitors who enjoy a social setting.
It also suits people who want a taste of St. Thomas from the water without giving up most of the day. The four-hour length leaves time for lunch, shopping, or another island plan, though the 9:30 a.m. start requires an early beginning.
The minimum age is 5, and the maximum is 80. The minimum height is 36 inches, and the maximum weight is 275 pounds. You should also have a strong physical fitness level and be comfortable with swimming or at least entering open water from the boat.
I would think twice if you are uneasy with speed, crowds, open-water snorkeling, or changing sea conditions. The tour has a beach component, but it is not simply a ride to a shallow, sheltered swimming area.
Weather, Timing, and Cancellation Flexibility
The activity depends on good weather. If poor weather causes a cancellation, you are offered another date or a full refund. The same applies if the minimum number of participants is not reached.
You can cancel for a full refund up to 24 hours before the start time. Changes or cancellations within 24 hours are not accepted for a refund, so keep the local cut-off time in mind when making plans.
The experience is usually booked well ahead, with an average booking lead time of about 43 days. That suggests you should not leave it until the last moment if this is a priority, especially if your St. Thomas visit has limited open days.
My Verdict on the SeaFari FastCat
SeaFari FastCat is a spirited, activity-packed half-day on the water. I like the fast ride, the two different beach stops, the included equipment, and the way the crew adds useful information and humor without making the trip feel like a formal lecture.
The strongest practical advantage is variety. You can swim, snorkel, float, paddleboard, play pickleball, enjoy rum drinks, and see the harbor from a fast catamaran, all in roughly four hours.
Book it if you want an energetic shared excursion and feel comfortable swimming from a boat in open water. Skip it if your ideal beach day means calm shallows, privacy, or long stretches of quiet. For the right kind of morning, $89 buys a lot of activity and a memorable look at St. Thomas from the sea.
