REVIEW · SNORKELING & CORAL REEF TOURS
SeaFari FastCat – Sun, Fun, Swimming, Snorkeling & Boat Party
Turbo speed on St Thomas, fast. SeaFari FastCat turns a simple half-day into a 1000hp thrill ride, with a scenic harbor loop out past Water Island and back, plus staff like Keith (manager) and crew members Victor and Ashley keeping the mood fun and easy.
I especially like the way this tour pairs speed with real time in the water. You get snorkel gear and flotation right at the stops, then beach time at Honeymoon Beach and Limestone Beach, with the chance to see green sea turtles and colorful fish while you’re swimming off the boat. One drawback to consider: snorkeling happens directly off the vessel in open water, so you’ll want good fitness and you should think carefully about sea conditions and any medical concerns.

Key highlights at a glance

Turbo-powered PowerCat cruise: A high-speed ride that makes the harbor views feel like part of the action.
Two secluded beach stops: Honeymoon Beach and Limestone Beach, each with about an hour to swim and snorkel.
Snorkeling off the boat in open water: You’re not jumping in from a pier, you’re easing into open water with guidance.
All-inclusive drinks and water gear: Rum punch, beer, snorkel mask, fins, floats, and even paddleboards.
Party vibe on the return: Rum drinks and music energy on the way back, not just a calm scenic cruise.
Smallish group for this kind of tour: Up to 80 travelers, which feels easier than huge party boats.

What You Get: 4 Hours of Power, Snorkeling, and Beach Time

For $89 per person, this is the kind of St Thomas outing where you’re not just “seeing.” You’re moving, swimming, and spending real time at two different shoreline spots. The big value is how tightly packed the experience is: you cruise out in a turbo-powered catamaran, then you actually get a full hour at each beach stop.
The boat is the 1000hp Breeze, and the tour is built around that energy. You’re also not stuck doing one thing only. You can snorkel, swim, float, and even use paddleboards and try pickleBall. If you want a vacation day that feels like a good mix of active and relaxed, this fits.
I also like that the experience stays practical. There are restrooms on board, snorkel gear is provided (mask, snorkel, and fins), and you’re not organizing your own rentals or transfers.
Turbo-Powered Harbor Run: Charlotte Amalie, Elephant Bay, and Water Island
Right after boarding at R Bar St Thomas, the pace picks up. You’ll race out of the harbor and make a loop that includes Charlotte Amalie harbor and viewpoints around Elephant Bay and Frenchman’s Cut. It’s the kind of route that helps you get your bearings fast, even if this is your first visit.
Then comes the fun part: circling around Water Island. This isn’t a slow “look and listen” cruise. The boat’s speed is the point. You feel the motion, you get constantly changing views, and you’re back before you’ve lost the morning to logistics or waiting around.
If you like boats but hate wasting time, you’ll probably enjoy this segment. You get the scenery, plus enough speed to keep the day from dragging.
Stop 1: Honeymoon Beach for Snorkel and Swim (Plus a Bar Option)

Honeymoon Beach is your first break from the boat. You have about one hour here, with snorkeling and swimming options using flotation devices. The setup is simple: you snorkel directly off the boat in open water, then switch back to swimming and floating when you want a breather.
This stop is also where the “relax” part of the day starts. You’re not forced to stay in the snorkel loop the whole hour. Use the flotation, hang out near the boat, and give your legs a rest between swims.
One practical plus: there’s a bar and restaurant available at this stop. That means if you want something other than what’s on the boat later, the option is there. (The tour includes drinks, but it helps to know food and drink access exists at the beach.)
Stop 2: Limestone Beach for Another Swim, Another Set of Fish

Your second beach stop is Limestone Beach, again with about one hour to snorkel and swim. Limestone Beach is the sister stop to Honeymoon Beach, and it matters because it increases your odds of getting comfortable in the water twice instead of only once. If one spot’s conditions feel a little rougher than you expected, the second hour gives you another chance to enjoy the water.
This is also where you’re set up for the famous Caribbean wildlife moment. The tour gives you the opportunity to swim alongside green sea turtles and colorful fish. That’s not something you can guarantee every single minute, but the whole point of the stop is to put you in the water with a good shot at it.
I like that the tour doesn’t pretend you’ll do everything the first time. Two beach stops let you settle into the rhythm, from boat to water to float to back.
More time on the water, one way or another
Snorkeling Off the Boat: The Real-World Part You Should Know

The biggest “read this twice” detail is how snorkeling works here. Snorkeling is done directly off the boat in open water. That means there’s no easy step-down from a dock, and your experience depends on day-of water conditions.
The tour also calls out medical caution for guests with cardiac conditions, asthma, diabetes, epilepsy, or other heart or respiratory conditions. Even if you don’t have a medical issue, open-water snorkeling usually means you should consider how you react to wind, waves, and current. If you get stressed by choppy water, plan mentally for a more active, less controlled entry.
Fitness also matters. You should have a strong physical fitness level, and there are size and age limits (minimum age 5, maximum age 80; maximum weight 275 lbs; minimum height 36 inches). Those rules help keep the snorkeling experience safer and more manageable for the majority of people.
If you’re the type who loves swimming but hates rough water, you’ll want to watch the conditions and be honest with yourself about what you can handle.
On-Board Fun: Rum Punch, Beer, Paddleboards, and PickleBall

This is not a quiet boat. It has a Caribbean party vibe, especially on the return journey. Throughout the tour, you get tropical rum drinks, including rum punch and beer. That does two things: it keeps the mood social, and it turns the ride back into a “hang out” moment instead of another waiting phase.
The included gear also adds variety. You get modern snorkel equipment (mask, snorkel, fins), plus floats, and paddleboards are available. Paddleboarding isn’t something every snorkeling tour includes, and that matters because it gives non-snorkelers something fun to do without standing around.
Even pickleBall is part of the mix, which is a surprisingly good way to break the ice if you’re traveling solo or with a mixed group (some swimmers, some just there for the vibe).
And yes, having restrooms on board is a big quality-of-life detail. When you’re out for about four hours, it removes a lot of stress.
Price and Value: Why $89 Can Feel Like a Deal Here

At $89 per person for a 4-hour experience, the value is in the bundle. You’re paying for a turbo-powered cruise plus two beach stops, not just one quick snorkeling slot. You also get snorkel gear and flotation gear included, which is often where other tours sneak in extra costs.
The drink inclusion matters too. Rum punch and beer are not just a nice extra. On a boat day, those included drinks help you avoid spending time and money every time you want something cool while you’re moving around the water.
You also get expert guidance and safety equipment on board, and that support matters for a tour that involves open-water snorkeling and swimming off the vessel.
So if you want a half-day that feels like multiple activities working together, the price makes sense.
Who Should Book SeaFari FastCat (And Who Might Skip It)

This tour is a strong match if:
- You want a fun, social boat day, not a private charter
- You like snorkeling and you’re okay entering the water from open water
- You enjoy mixed activities, swimming plus time on beaches plus onboard games and paddleboards
- You want drinks included and you don’t want to fuss with rentals
It might be less ideal if:
- You’re unsure about open-water entry or you get uncomfortable in wind and waves
- You have medical conditions the tour warns about (especially heart or respiratory concerns), and you haven’t cleared water activity with your doctor
- You want a slower, calmer cruise where snorkeling happens from a dock or beach entry
If you’re traveling with kids, note the minimum age is 5. The experience is active, so choose it if your kids can handle getting in and out of the water comfortably.
Smart Planning: Where to Meet and How to Make It Easy
Start time is 9:30 am, and the tour begins at R Bar St Thomas on Yacht Haven Grande, Suite S-104 (Unit 61), in Charlotte Amalie. The good news for logistics is that parking is available at the meeting point, and it’s near public transportation.
Because it’s a mobile ticket experience, have your ticket ready on your phone before you arrive. That small habit avoids last-minute scrambling.
Also, remember it’s scheduled for about four hours total, and you’re moving between the harbor ride and two beach stops. I’d treat it like an actual half-day outing, not an add-on. Plan your day around it.
One more practical note: the experience requires good weather. If conditions aren’t right, you might be offered a different date or a full refund if it gets canceled due to poor weather.
Should You Book SeaFari FastCat?
If you want the best mix of speed, scenery, and water time in St Thomas, I think this is worth booking. The turbo-powered boat ride keeps the day from feeling slow, and the two separate beach stops give you enough time to enjoy snorkeling without feeling rushed. Add in the included gear, flotation, rum punch, beer, paddleboards, and the party energy on the way back, and you get a lot for $89.
I’d only skip it if open-water snorkeling from the boat makes you nervous, or if your health situation calls for extra caution. If that’s you, you might want a different style of snorkeling tour with a more controlled entry.
If your idea of a great day is swim, snorkel, lounge, and laugh with a lively crew, SeaFari FastCat is one of the easier yes decisions you’ll make in St Thomas.
