REVIEW · ST THOMAS
Private Full Day Sail/ Snorkel Experience USVI (Sapphire Marina, STT pick up)
Book on Viator →Operated by Sailing The Cosmos Charters · Bookable on Viator
A private sail day in the Virgin Islands feels personal. This full-day charter from Sapphire Beach (Smith Bay, St Thomas) turns you loose on your own timetable, with Captain Rob and Deb helping you shape the day. You’re on the water with the boat basically to yourselves, plus a crew that works with what you want to do.
Two things I really like: the flexibility to sail longer, snorkel longer, or just hang on deck. And the lunch is not some sad snack—Deb makes a homemade meal that shows up as crab cakes and salad in the best possible way.
One possible drawback: the price is steep if you don’t fill the boat. Also, you’ll want to plan for basics like towels (not included) and a reef-friendly sunscreen since sprays/oils aren’t allowed.

Key Highlights You’ll Actually Feel

- Private charter for up to 6: your group sets the vibe, not a crowd schedule
- Snorkeling included: equipment and flotation water toys are part of the deal
- Deb’s onboard lunch: homemade crab cakes and salad show up more than once in the feedback
- Choose the water time: sail, anchor, swim, snorkel, or relax at the stops your captain selects
- Crew help getting in and out: especially helpful if you’re restarting snorkeling or traveling with kids
A Private Boat Day from Sapphire Beach (and Back)

This is built like a true private day. You meet at Sapphire Beach, Smith Bay, St Thomas (00801) and the experience ends back at the same starting point. The start time is 9:00 am, and the full day runs about 7 hours.
What that means for you is simple: you’re not negotiating with other groups for the same snorkel moments or scrambling to match someone else’s plan. Instead, your captain and Deb can work around your comfort level—whether that’s more sailing time, more swimming time, or a calmer day where you mostly sit back and enjoy the motion of the boat.
There’s also a practical comfort advantage here: the charter includes easy access for boarding and disembarking, with a dock slip. That helps when you’re carrying snorkel gear, kids are getting ready, or you just don’t want a complicated transfer at the end of the day.

Your Day to Shape With Captain Rob and Deb

The core idea is customization. You tell the crew what you want: sail all day, do a snorkel-focused plan, or mix in quiet anchored swimming breaks. Captain Rob and Deb set you up so you can make decisions without feeling rushed.
If you love sailing, you can keep the day moving and treat snorkel stops like short breaks rather than the whole point. If you want sea time with underwater looks, the crew can steer you toward strong spots around the islands. From the feedback, snorkel variety often includes options such as Honeymoon Beach plus other top areas around St. John and Greater St. James.
Here’s how to make the customization work for you: before you step onboard, think in categories. For example:
- How many times do you really want to get in the water?
- Are you okay with both snorkeling and swimming, or do you want one to lead?
- Do you want a long sail segment between stops, or shorter cruising legs?
Because it’s private, you’re not stuck with a one-size itinerary. You’re also not stuck trying to talk to a captain while everyone else is watching the clock.
Snorkeling Gear, Float Toys, and Getting Comfortable in the Water

Snorkeling is a big part of this day, and it’s handled the easy way: snorkeling equipment is included, along with flotation water toys. That matters because it removes the hassle of renting gear last minute or trying to make do with something that doesn’t fit.
The crew also shows up as part instructor. Several reviews mention the help getting into and out of the water and guidance for people who were nervous about snorkeling again. That’s a real value, because snorkeling confidence is mostly about knowing what to do once your face is in the water and how to clear your mask.
One very practical safety note from the details: the swim ladder has a rated max capacity of 260 lbs. If that’s relevant for anyone in your group, it’s worth planning around it.
Also, you’ll have more fun if you treat snorkel time like a gentle activity, not a test. Take your time. Use the crew’s setup cues. Keep an easy rhythm. And if someone in your group is not snorkeling, the day can still work—one review describes a husband who lounged while the others snorkeled, and the boat stayed calm and enjoyable for everyone.
Honeymoon Beach and Other Anchor-and-Swim Stops

You’ll anchor and swim. Then you’ll snorkel. Then you’ll do it again if conditions and your preferences line up. That rhythm is the heart of the day, and it’s why this charter works so well for people who don’t want a rushed, check-the-box tour.
One named option is Honeymoon Beach. That’s useful for you because it gives you something tangible to look forward to, rather than a vague plan of water stops. But it’s not the only kind of experience the captain can deliver.
Based on the feedback, the captain tends to choose strong snorkeling spots in the broader area, including coves and sites that can produce a good mix of colorful fish and larger sea life. Several reviews specifically mention sightings like sea turtles, and in one case sting rays.
What’s the possible drawback with anchor-and-swim itineraries? The day depends on weather and sea conditions. The experience is described as requiring good weather, and the reality is that time spent in the water can shift based on wind, wave height, and water clarity. If you’re the type who wants guaranteed underwater “wow” every minute, you’ll still likely have a great time—but you have to accept Mother Nature has a vote.
My advice: aim for a flexible mindset. If you build your expectations around a great sail day with multiple chances to snorkel, you’ll stay happy even when the sea isn’t in perfect postcard mode.
Lunch on the Water: Deb’s Homemade Crab Cakes and Salad

Lunch is included, and it’s not just a box. The tour details say Deb prepares a homemade lunch onboard, and the reviews repeatedly bring up crab cakes in a way that sounds like a real highlight, not a polite mention. One review even points to Lumpo crab cakes, which tells me it’s trying to be more than generic fare.
Why this matters for your day: you’re staying on the water, so you’re not burning time on shore meals, taxis, and parking. When you’re paying for a full-day sail, that “no land break” piece is part of the value.
If you’re sensitive to taste, texture, or spice, check with the crew ahead of time. The info you have doesn’t list dietary options, so you don’t want to guess. But you can still plan confidently: you’re getting a real lunch made onboard by Deb, and the vibe is relaxed.
Also, the boat-to-lunch flow is part of the pace. After a snorkel stop, it’s a treat to dry off, eat something satisfying, and then decide whether you want to snorkel again or just enjoy sailing.

Water Comfort Details: Fresh Shower Rinse and Sunscreen Rules

You’ll get a fresh water shower rinse onboard. That’s one of those small things you appreciate more as soon as you’re out of the ocean. It helps you feel less sandy, less sticky, and more ready to enjoy the rest of the day (and the ride back).
Two things you should plan for: towels are not included, and the sunblock policy is specific. The details say there is no sprays or oils, and you should look for reef-safe products if possible. That’s more than a rule for the sake of rules. Spray sunscreens can disperse into the water, and oily formulas can degrade reefs.
So bring what works for you: reef-safe lotion-style sunscreen and a towel for after your swims. If you forget the towel, you’ll still be fine, but you’ll feel the annoyance.
And remember the physical level: the experience says travelers should have moderate physical fitness. Even with easy boarding access, you’re on a moving boat, you may be climbing ladder steps, and you’ll be spending time in swim gear. If your mobility is limited, you’ll want to think about whether the water entry and ladder setup will work comfortably for you.
Price and Value: What $1,975 Gets Your Group

The price is $1,975 per group, up to six people. If you fill it completely, that’s roughly $330 per person for about 7 hours of private sailing and snorkel time. If your group is smaller, the per-person cost rises fast, so value depends on whether you can split the boat fairly.
Here’s what you’re paying for that matters:
- Private boat time (not sharing with strangers)
- Snorkeling equipment and flotation toys included
- Homemade onboard lunch prepared by Deb
- Fresh water shower rinse onboard
- Dock slip access that makes boarding and getting off easier
Don’t ignore the items not included: crew gratuity (industry standard 15–20%) and towels. Sunblock is also on you. Those aren’t surprises, but they do affect your total budget.
My take: this is a strong value when you have a full group who will use the flexibility. If your priority is a peaceful, guided day on the water—with real attention, not a packed schedule—this fits. If you’re traveling as a couple and you mostly want one quick snorkel and minimal sailing, you might feel the cost more than a family who actually uses the full charter time.
Who This Private Sail/Snorkel Fits Best

This experience is a great fit if you want:
- A calm, peaceful day on a sailboat (not a sprint through attractions)
- Real snorkeling support, especially for people who want coaching or help getting in and out
- Time that works for both snorkelers and non-snorkelers
- A family-friendly plan where kids can have a meaningful day on the water
The feedback includes examples of a family with kids who saw sea turtles and even mention a very picky child being thrilled. That doesn’t mean every child will love snorkeling, but it does suggest the crew knows how to keep the experience pleasant and not stressful.
Also, because the itinerary is flexible, it works for couples too, including honeymoon-style beach choices like Honeymoon Beach. If you want a romantic day that still includes tangible water time, a private charter is the right format.
Quick Practical Tips Before You Go
A few moves that will make your day smoother:
- Bring a towel since it’s not provided.
- Pack reef-safe sunscreen in lotion form (no sprays or oils).
- If snorkeling is new for you, plan to follow the crew’s help for mask setup and getting in/out.
- Don’t over-plan your expectations: the water depends on conditions, and the crew adjusts.
- If you’re worried about the ladder or entry, ask about comfort needs early, especially with the 260 lbs ladder capacity noted.
Should You Book Sailing The Cosmos at Sapphire Beach?
If you can fill the boat with up to six people, and you want a true private day with snorkeling gear, flotation toys, homemade lunch, and onboard rinse, I think this charter is an easy yes. You’re buying flexibility and attention—plus the chance to hit strong snorkeling areas around St Thomas, St John, and Greater St. James.
I’d reconsider if you’re cost-sensitive as a small party or if your group has concerns about moderate mobility needs on a boat (ladder entry, moving deck, time in swim gear). For everyone else, this is the kind of day that feels like your own vacation rather than a schedule you survived.
