Private Full Day Sail/ Snorkel Experience USVI (Sapphire Marina, STT pick up)

The best part of this St. Thomas charter is simple: the boat is yours for the day. Captain Rob and Deb can shape the route around your group, taking you to places such as Honeymoon Beach, Christmas Cove, St. John, or Greater St. James when conditions and timing allow.

I like the easy, friendly pace and the fact that you are not pushed through a fixed schedule. I also like the practical extras: homemade crab cakes and salad, snorkeling gear, flotation toys, and a freshwater rinse. The main consideration is the price. At $1,975 for up to six people, this makes the most sense for a full group rather than a couple traveling alone.

Key points to know before booking

• Private sailing aboard Cosmos: Your group of up to six has the boat to itself for roughly seven hours.
• Captain-led custom route: Rob and Deb can adjust the day around sailing, snorkeling, swimming, beach time, or simply relaxing aboard.
• Strong snorkeling possibilities: Stops may include Honeymoon Beach, Christmas Cove, St. John, and Greater St. James, with sightings such as turtles, stingrays, and colorful fish possible.
• A real lunch, not just a snack: Deb prepares a homemade meal, with crab cakes and salad especially praised by past guests.
• Useful water gear included: Snorkels, masks, flotation toys, and a swim ladder are provided.
• Plan for the practical details: Bring towels and reef-safe sunscreen without sprays or oils, and expect to pay a 15 to 20 percent crew gratuity.

A private day on the water from Sapphire Marina

This excursion begins at Sapphire Beach in Smith Bay at 9:00 a.m. You meet the crew at the dock, with an easy boarding setup rather than a beach launch. That small detail matters if you are carrying bags, helping children aboard, or simply prefer not to wade into the water.

The day lasts about seven hours. Since the charter ends back at the same meeting point, you do not need to arrange a separate ride from another island or beach. The location is also near public transportation, though the information provided does not promise hotel pickup, so you should plan your arrival at Sapphire Beach separately.

Once aboard Cosmos, the basic shape of the day is yours to discuss with Rob and Deb. You can ask for more sailing, more time in the water, a quiet anchorage, or a balanced mix. That flexibility is the central reason to choose this trip over a shared boat with a set route.

A custom plan does not mean every requested stop is guaranteed. Wind, sea conditions, and the time needed to reach an area will affect the captain’s choices. The smart approach is to arrive with a short wish list, then let the crew build a sensible route around the day’s conditions.

What the sailing portion feels like

If you enjoy the movement of a sailboat, this is more than a ride between snorkeling spots. You have time to sit back, watch the coast pass, and enjoy stretches of quiet water without a loud crowd around you. Several past guests specifically valued the peaceful feeling of sailing and the chance to simply relax aboard.

Cosmos is described as a roomy, well-maintained sailboat. Rob and Deb live aboard, so the boat is also their home. That can make the atmosphere feel personal and informal, but it is worth remembering that a private sailboat is not a floating resort. You should expect a comfortable working boat with room to sit, move around, eat, and get into the water, rather than a large cruise vessel with endless space.

The captain and first mate handle the sailing while you choose how active you want to be. One person can snorkel while another stays aboard, reads, rests, or enjoys the views. This is especially useful for families and mixed groups. A non-snorkeler does not have to spend the day feeling like an extra passenger at a water activity.

Snorkeling around St. Thomas, St. John, and nearby islands

Snorkeling is a major part of the charter, but it is not locked to one reef. Rob can suggest locations, and the group can give input. Possible areas mentioned for this trip include Honeymoon Beach, Christmas Cove, St. John, and Greater St. James.

Honeymoon Beach is one possible snorkel stop and offers a change from snorkeling directly off the boat. Other stops may be reached by sailing to a quieter area and anchoring. The appeal of a private charter is that you can spend more time at a place your group enjoys instead of being pulled away on a fixed timetable.

Christmas Cove is another noted option. Past outings in this area included sightings of sea turtles, stingrays, and many colorful fish. These are wildlife encounters, not a promise, so conditions and luck still matter. Still, the captain’s ability to choose among several areas gives you a better chance of finding pleasant water on the day.

The equipment is included, which saves you from renting masks, snorkels, and flotation gear separately. If you are rusty at snorkeling, the crew can help you get comfortable in the water. One couple arrived nervous about getting back into snorkeling and received assistance getting in and out. That kind of hands-on help is useful, but you should still be comfortable in the water and have a moderate level of physical fitness.

The boat has a swim ladder with a maximum rated capacity of 260 pounds. Pay attention to that limit when deciding if this activity suits everyone in your group. Boarding and leaving the water require enough mobility to use the ladder, even though dock access at the start and end is described as easy.

Lunch aboard Cosmos

Lunch is one of the more distinctive touches here. Deb prepares it herself, and crab cakes with salad appear repeatedly as the featured meal. That is a welcome step above the usual packaged sandwiches found on many boat trips.

You eat onboard, most likely during a natural pause in the sailing and snorkeling schedule. The meal gives the day a proper break, and it means you do not have to interrupt the charter to find a restaurant ashore. Snacks and drinks have also been provided on some outings, but the listed inclusion specifically confirms lunch, not a full open bar or a detailed beverage package.

Food preferences are not specified, so you should ask about allergies or special diets before booking. Do not assume the menu can be changed unless the operator confirms it. Bring any personal snacks or drinks you know you will need, especially for children.

Water toys, showers, and what to pack

The charter includes flotation water toys as well as snorkeling gear. These are useful for a group with different ideas about fun. Strong swimmers can snorkel, children can use the floats, and anyone who prefers a slower afternoon can remain aboard.

A freshwater shower rinse is also provided after swimming. It is not a substitute for a full shower, but it helps remove salt from your skin before the ride back to Sapphire Beach. Towels are not included, so pack one for every person in your group.

Sunscreen requires some care. Sprays and oils are not permitted, and reef-safe products are requested when possible. Bring a lotion-style sunscreen and apply it before boarding if you can. The rule protects the boat and the water, and it also saves you from arriving with the wrong product.

A practical packing list includes:

• Towels
• Reef-safe, non-spray sunscreen
• A swimsuit and dry clothes
• Any personal medication
• Extra snacks or drinks if needed
• A waterproof pouch for small valuables

The provided information does not list storage space, so avoid bringing bulky luggage. This is a day on a sailboat, not a place to bring a full beach bag for each person.

Why the private format matters for families and couples

A shared excursion can be a good bargain, but it usually asks everyone to follow the same timetable. This charter gives your group more control. You can stop snorkeling when the youngest child gets tired, allow a non-swimmer to relax aboard, or spend more time sailing if the water is calm and pleasant.

Families have used the boat with children, including a seven-year-old who enjoyed seeing turtles and stingrays. That does not mean every child will be comfortable on the water. You should consider swimming ability, attention span, and comfort with a moving boat before committing to seven hours.

Couples can enjoy the same flexibility in a quieter way. If you want a private day with time to talk, sail, and stop for a swim, the boat gives you space away from a large group. The drawback is financial: two people would effectively pay $987.50 each if they split the listed group price evenly. That is a substantial cost compared with a shared half-day tour.

For six people, the arithmetic looks much better at about $329 per person. For four people, it is about $494 per person. I would compare the total against other private charters in St. Thomas, then decide how much the personal route, lunch, and seven-hour duration are worth to your group.

The crew and the tone of the day

Rob handles the captain’s role, while Deb helps with hosting, food, and trip planning. Their style is described as welcoming, flexible, and attentive without making the day feel formal. That matters on a private charter, because you will spend most of the day in close quarters with the crew.

Communication before the trip is also a useful part of the experience. Deb has helped groups plan details in advance, and the crew has adjusted arrangements when practical. You should use that contact to explain your group’s swimming abilities, food needs, and preferred balance of sailing and snorkeling.

The tone is laid-back rather than action-packed. You can get plenty of activity from snorkeling and swimming, but the trip also leaves room for sitting quietly on deck. If you want nonstop water sports or a party boat, this may feel too calm. If you want a relaxed day with options, it fits better.

Timing, weather, and cancellation terms

The start time is 9:00 a.m., and the duration is approximately seven hours. That makes this a full-day commitment. I would avoid scheduling another major activity immediately afterward, especially if you need to travel across St. Thomas after returning to Sapphire Beach.

Good weather is required. If poor weather forces a cancellation, you will be offered another date or a full refund. For your own cancellation, you can receive a full refund if you cancel at least 24 hours before the start time. Changes or cancellations made inside that 24-hour window are not accepted for a refund.

The operator confirms the booking at the time of reservation. Since this private charter is booked an average of 34 days ahead, I would reserve early if you have a narrow vacation schedule or need a specific day.

Who should book this St. Thomas charter

I would consider this trip a strong match for:

• A group of up to six that wants a boat to itself
• Families with mixed swimming and snorkeling interests
• Couples who place a high value on privacy
• People who enjoy sailing, not just arriving at a beach
• Groups that appreciate a homemade lunch and a relaxed pace
• Snorkelers who want more than one possible stop

I would think twice if your group dislikes boats, needs a highly accessible water entry, or wants a guaranteed list of exact beaches and wildlife sightings. The swim ladder has a 260-pound maximum rating, a moderate fitness level is recommended, and conditions can change the route.

You should also be clear about the cost before booking. The $1,975 price covers the private group, not each passenger, and includes lunch, snorkeling equipment, flotation toys, and the freshwater rinse. Gratuity is extra, with 15 to 20 percent given as the stated industry standard.

Should you book Sailing the Cosmos?

Book it if you can fill most of the six available places and want a personal day on the water rather than a standard group outing. The strongest reasons are the flexible route, the peaceful sailing, the chance to snorkel in several areas, and Deb’s homemade crab cake lunch.

I would not choose it simply because you want the cheapest way to see St. Thomas. A shared tour will usually cost less. But if privacy, time, and control matter to you, the price becomes easier to justify, especially with five or six people sharing it.

For a relaxed group that wants to sail, swim, snorkel, eat well, and set its own rhythm, this is a very appealing full-day charter from Sapphire Beach.
