Small boats make a big difference. Aqua Action Dive Center takes certified SCUBA divers from Secret Harbour on a 3.5-hour boat trip around St. Thomas, with two underwater stops, reef and wreck sites, and a maximum of 12 people aboard. I like the limited group size and the fact that tanks, weights, BCDs, regulators, wetsuits, masks, fins, and snorkels are included.

I also like the relaxed touches: water and fresh fruit during the surface interval, plus a crew that has been praised for patience, useful pointers, and a friendly attitude. The main concern is practical rather than underwater: the trip needs a minimum number of participants, and one serious complaint involved poor communication after a departure was canceled.

Key points to know before booking

Two Tank Dive - Key points to know before booking

  • Two underwater stops from a 32-foot island-hopper boat: You get a morning or afternoon outing built around two SCUBA sessions.
  • A maximum of 12 people: The small capacity should make boarding, gear setup, and attention from the crew easier.
  • Reefs, shipwrecks, turtles, and tropical fish: The exact sites can vary, but the trip is aimed at some of St. Thomas’s most appealing underwater scenery.
  • Equipment is included: Tanks, weights, BCDs, regulators, wetsuits, masks, fins, and snorkels are part of the $200 price.
  • Certification and recent experience are required: You must show proof of certification and experience within the past two years.
  • A little booking caution: Poor weather or too few participants can cancel the trip, though you should receive another date or a full refund.

Meeting at Secret Harbour for a compact boat outing

Two Tank Dive - Meeting at Secret Harbour for a compact boat outing

Your starting point is Secret Harbour Beach Resort at 6280 Estate Nazareth in St. Thomas. The trip returns to this same meeting point, so you do not need to arrange a second pickup location at the end.

The boat is a 32-foot island hopper, a useful size for reaching offshore sites without committing to a huge commercial operation. With room for no more than 12 people, the atmosphere should feel more personal than a crowded party boat. You will still need to share the boat and equipment space, but a smaller group generally makes the morning or afternoon easier to manage.

The timing is also convenient. You can choose a morning or afternoon departure, and the full outing lasts about three and a half hours. That leaves room for other plans in St. Thomas, although you should avoid scheduling anything too tightly afterward. Boat trips, gear handling, and weather can make exact return times less predictable than the advertised duration.

The basic plan is simple: board the boat, travel to the selected sites, complete one underwater session, rest during a surface interval, and then continue to a second site or another nearby location. The trip is designed for certified participants, not for first-time instruction.

The first stop gives you time to settle into the local conditions and get comfortable with the equipment. Your Dive Master leads the group around the site and points out the marine life and features worth noticing. The operator highlights Caribbean reefs and shipwrecks, so the appeal comes from variety rather than one fixed attraction.

After the first session, you return to the boat for a surface interval. Complimentary water and fresh fruit are provided, which is a small but welcome detail in the warm Caribbean climate. Use this break to drink water, rest, and listen carefully to the crew’s instructions for the next stop.

The second session gives you another chance to see fish, reef life, turtles, rays, lobsters, or wreck features. Those animals are not guaranteed, and the exact sites can change, but the reported sightings show the sort of marine life that may be present. The two-session format also gives you a better chance to see different underwater settings than a single short outing.

Reefs, wrecks, turtles, and fish

Aqua Action’s strongest appeal is its choice of subject matter. Reefs offer color, structure, and active marine life, while shipwrecks add a sense of exploration without requiring a full-day expedition. The wrecks may be especially appealing if you have already seen standard reef sites and want more shape and story beneath the surface.

The marine life list is equally inviting. Fish, lobsters, rays, turtles, and other Caribbean species have all been reported on this trip. You should treat that as a possibility rather than a promise, since wildlife moves freely and conditions change from site to site.

I like the balance here. This is not marketed as a single-animal encounter, so you are not paying for a guaranteed turtle sighting. Instead, you get two chances to explore sites selected by the crew, with the possibility of seeing a broad mix of reef animals and wreck life.

The trip is best for someone who enjoys looking closely rather than rushing from one sight to another. A patient pace matters underwater. One particularly positive account praised the crew member who gave helpful pointers and remained patient throughout the sessions, a valuable quality if you need a moment to adjust your position or equipment.

Equipment included in the $200 price

The $200 per-person price covers the main gear you need for the outing:

  • Tanks
  • Weights
  • BCD
  • Regulators
  • Wetsuits
  • Masks
  • Fins
  • Snorkels
  • Water
  • Fresh fruit

That list makes the cost easier to assess. You are not paying only for a boat ride and a guide. The price also covers the core SCUBA setup, two tanks, crew support, and the use of the operator’s boat for about three and a half hours.

For a certified diver traveling without personal equipment, this is a practical arrangement. You avoid bringing bulky gear to St. Thomas or arranging separate tank rental. If you own your own mask, fins, or regulator, you may still prefer familiar equipment, but the included package reduces the amount you must organize before the trip.

Before booking, confirm any personal equipment preferences directly with the operator. The supplied information confirms that standard gear is included, but it does not explain brands, sizes, camera policies, or whether personal equipment changes the price.

What the crew adds to the experience

The operator emphasizes professional service and a safe, relaxed atmosphere. That matters on a boat trip where good organization is just as important as the scenery. You want clear instructions, sensible site planning, and a crew that notices when someone needs help.

The strongest praise focuses on the people onboard. One account described the crew as friendly and credited the Dive Master with useful tips and patience. Another praised the crew from the first impression through the end of the day and described the underwater sessions as impressive.

That combination is important for mixed-experience groups. Everyone must hold certification, but certified people can still have different comfort levels, recent experience, and familiarity with boat procedures. A calm crew can make the difference between feeling rushed and enjoying the outing.

The small capacity helps here. With no more than 12 people, the crew has a better chance to keep track of the group and answer questions. It does not guarantee a private experience, and the boat may still feel busy when everyone is preparing at once, but it is a favorable limit for a half-day trip.

Fitness, certification, and who should book

You must provide evidence of certification and show experience within the past two years. This requirement is important. The trip is not a beginner lesson, and you should not book it if you cannot document recent experience.

The activity also calls for a moderate level of physical fitness. You will need to handle standard boat and SCUBA procedures, manage your equipment, and participate in two sessions with a surface break between them. The supplied information does not give a detailed medical checklist, so anyone with health concerns should ask the operator before paying.

This outing suits certified people who want a short, organized way to explore St. Thomas by boat. It is a good fit if you want reef and wreck scenery, prefer a small group, and do not want to rent every item separately.

It is less suitable if you are looking for an introductory lesson, a private charter, a guaranteed turtle encounter, or a full-day schedule with many sites. The 3.5-hour format is focused and manageable, but it naturally limits how much coastline and how many locations you can cover.

The main concern: minimum numbers and communication

The cancellation terms deserve attention. The operator can cancel if poor weather makes the trip unsuitable or if the minimum number of participants is not reached. In either case, you should be offered another date or experience, or a full refund.

That policy is reasonable for a boat operation. Weather can affect safety, and running a small boat with too few people may not be workable. Still, one very negative account described arriving with no trip and difficulty reaching the operator about a refund. The response explained that the shop had recently changed ownership and that its booking communication had not been as attentive as it should have been.

This is the clearest warning in the available information. I would not ignore it, especially if the trip is tied to a cruise schedule or a short St. Thomas stay. Confirm the departure shortly before the outing, keep written confirmation, and make sure you understand how a cancellation will be handled.

You can cancel for a full refund if you do so at least 24 hours before the start time. Changes or cancellations inside that 24-hour window are not accepted and are not refunded. Local time controls the cutoff.

Is $200 a fair price?

At $200 per person, this is not a bargain-basement activity, but the price includes a substantial package. You receive two tanks, the major pieces of rental gear, boat transport to the sites, crew support, water, fruit, and roughly half a day on the water.

The value is strongest for visitors who need equipment. Buying or transporting a full personal setup would be far less convenient, and separate rentals can quickly add to the cost of a boat outing. The small group also adds value, particularly if you prefer direct attention over a large operation.

The value is weaker if you already own all your equipment and are mainly paying for access to the water. In that case, compare the price with other St. Thomas boat operators and check what each includes. Pay attention to tank count, group size, boat type, and whether food or gear rental is extra.

I would judge the price as fair for a two-session, equipment-included trip, provided the small-group format and selected sites match what you want. You are paying for convenience and crew support as much as for the underwater scenery.

Booking advice for a smoother day

Bring proof of certification and be ready to show evidence of experience within the past two years. Do not assume that a verbal explanation will be enough, since the requirement is stated clearly for all certified boat participants.

Arrive at Secret Harbour Beach Resort with enough time to get organized. The supplied information does not give a precise check-in time, so confirm that detail with Aqua Action before the outing. You should also ask about the morning or afternoon departure you selected.

Wear practical clothing for a boat trip and plan to use the surface interval for water and rest. The operator provides water and fruit, but the supplied details do not confirm any other meals, so do not treat this as a catered half-day excursion.

Finally, confirm the trip if your schedule is tight. The minimum-participant rule and weather requirement are normal for this type of operation, but they matter more when you have limited time on the island.

Should you book Aqua Action?

I would book this trip if you are a certified SCUBA participant with recent experience and want two organized boat sessions without spending a full day on the water. The best reasons are the 12-person maximum, included equipment, reef and wreck options, and the crew’s praised patience and friendly service.

I would pause if you need perfect communication, a guaranteed departure, or a private boat. The minimum-number rule creates some uncertainty, and the past complaint about a canceled outing and refund contact is worth taking seriously.

For the right person, this is a practical St. Thomas choice: compact, equipment-inclusive, and focused on the underwater sites rather than unnecessary extras. Confirm your booking close to departure, bring your certification evidence, and you will have a better chance of enjoying the relaxed half-day outing Aqua Action is aiming to provide.
