EcoPro Mariana — a small, personal Maldives liveaboard built around diving

The EcoPro Mariana is for divers who would rather know the people on board than disappear into a crowd. Sixteen guests is small enough for the crew to learn everyone's habits, and the separate dhoni keeps the main boat from becoming a working dive platform all day. The choice is less about polished luxury than about a manageable liveaboard where the diving stays central and the atmosphere remains personal. The scores reflect that balance: the boat receives 8.3, while the crew and diving both score 8.7 and the food 9.0. The hull is not the newest option in the Maldives, but the 2021 renovation, clean cabins and attentive operation matter more once the first dive begins. This is a sensible boat for a diver travelling alone, as a couple, or with a small group who wants repeated access to channels, thilas and pelagics without sharing the trip with two dozen other passengers.

At the dock, the Mariana presents herself as a traditional-style Maldivian safariboat rather than a floating resort. The lines are practical, the spaces easy to read, and the diving operation is visibly separated from the living areas by the second boat that carries the compressor and equipment. Once aboard, the main salon and bar provide an indoor base, while the upper deck and sundeck open the boat to air, shade and the view of the atolls. The 2021 renovation shows in the guest areas without erasing the boat's older character. Movement is straightforward: cabins below or above, the salon in the middle of daily life, and the dhoni handling the wet work. With only 16 guests, faces become familiar quickly. That changes the boat more than another layer of decoration would.

The atmosphere is shaped by the guest limit more than by any single feature. Sixteen people share the boat, so a solo traveller is not lost in a large departure and a small group does not need to shout across a crowded deck. Guests describe a crew that stays available through the day, with professional dive organisation, friendly service and practical help when conditions offer something unexpected at the surface. That matters in the Maldives, where the plan can change with current, weather or an animal appearing beside the boat. The evening is usually a return to the salon or upper-deck bar, with stories from the last dive and the next briefing still ahead. The Mariana's boat score is lower than its crew score, a fair indication that the vessel has aged while the people operating it are the stronger part of the experience.

The Central Atolls route links North and South Malé, Vaavu and Ari, with 8-day/7-night departures recorded for the classic itinerary. The longer Best of Maldives version runs for 8 to 12 days and 7 to 11 nights, extending into selected southern atolls. The sites explain the appeal. At Barracuda Giri, three submerged pinnacles rise into strong current, where barracudas, tunas, jacks and schooling fish gather; the maximum depth is -30m. Banana Reef brings reef structure and lively fish life near Thulhagiri Island Resort, with reef sharks and eagle rays among the possibilities. Mushimasmigili Thila reaches -30m and puts divers at an up-current pinnacle known for grey reef sharks. Dhonkalo is a manta cleaning station in a sandy channel, with a maximum depth of -25m. Maamigili and Maamigili Beiyru, both to -30m, sit in the South Ari Marine Protected Area, where whale sharks and mantas are the draw. Kudarah Thila adds clefts, overhangs and caves to -30m, with batfish schooling around the pinnacle. Guraidhoo and Myaru Kandu bring current-fed channels and sharks; Myaru Kandu reaches -30m. Foththeyo Kandu is the deeper, more committed site, with caves covered in yellow soft coral and a maximum depth of -40m. Further north, Dhigalhi Haa and Dhonfanu in Baa Atoll offer coral-rich thilas, manta cleaning stations and a sheltered swim-through, both to -30m. Dhigu Thila reaches -30m, while Fushifaru Thila reaches -35m and is known for manta cleaning stations.

The route is built around large animals rather than a single signature sighting. Napoleon wrasse, grey reef sharks and fusiliers are recorded at nine sites; sea turtles occur at eight, while barracudas, manta rays and tuna appear across seven. Eagle rays, jacks, giant trevally and white-tip reef sharks add movement to the channels and pinnacles. The setting explains the pattern: current concentrates pelagic fish around up-current points, and cleaning stations bring mantas and sharks back to particular reefs. South Ari's Maamigili and Maamigili Beiyru are the places to look for whale sharks and mantas, while Dhonkalo is specifically a sandy-channel manta station. Some sightings justify one particular descent. Barracuda Giri is the recorded site for groupers and anthias; Banana Reef for anemones; Maamigili for sweetlips and porcupinefish; Dhigalhi Haa Marine Reserve for soft coral and gorgonians; Fushifaru Thila Marine Reserve for stingrays; and Dhigu Thila for hawksbill turtles. These are possibilities, not promises, but the route gives each encounter a reason and a place.

English is the working language on board. A naturalist guide is part of the operation, and the guides brief each site before divers enter the water rather than leaving the plan to guesswork. Diving is organised in buddy teams; solo divers are assigned a buddy, and a guide may keep a diver on board if that diver's ability does not match the planned dive. The boat welcomes beginners through experienced divers on the Central Atolls route, while the more demanding southern itineraries call for Advanced Open Water certification and at least 50 logged dives. Everyone must carry a dive computer, and SMBs and reef hooks are required for the safari's drift-diving conditions. Oxygen, first-aid kits, GPS, VHF/DSC/SSB radio and satellite communication are carried for safety. Decompression, solo and technical diving are not allowed. Courses can be arranged on board when the itinerary and availability allow.

Diving is done from a dedicated dhoni, the second boat that carries the compressor, tanks and dive equipment. Divers kit up there, enter from its diving platform and return to the same working space rather than bringing wet gear through the Mariana's salon. The dhoni is supported by a skiff for surface operations. There are 12-litre DIN tanks with INT adapters, while 15-litre tanks are available to rent on request. Nitrox is available for an extra charge, subject to demand and technical availability; the system is a Nitrox membrane setup with Bauer compressors. The deck has tank racks, rinse tanks and a dedicated camera rinse area, with charging stations for cameras and equipment. Rental equipment is available in limited quantity and must be requested before the trip. Divers are expected to bring or arrange an SMB, reef hook, dive computer and torch for night dives.

Between dives, the Mariana gives guests a choice rather than a programme. The air-conditioned salon and bar are the practical refuge after a current dive, while the shaded sundeck and observation areas suit anyone who wants wind, sun and a clear view of the atolls. The upper deck has space to sit near the bar, and the boat also carries a library, photo space and separate camera rinse area. The dhoni takes care of the tanks and wet equipment, so the main deck can remain a place to eat, talk or leave a camera charging. On a no-dive stretch, the value is in that separation: the liveaboard feels like a small base at sea, not a dive centre with bunks attached. Beach barbecues and island or sandbank stops may break up the time on board.

A day begins with the boat's diving operation rather than with a hotel breakfast schedule. Divers move to the dhoni, hear the site briefing, check their buddy and enter from the platform. The published programme is about three dives a day, with night dives included on the safari; the exact sequence follows the site, current and conditions. Between entries, breakfast, lunch, snacks and dinner keep the day anchored, while the salon, shaded deck and upper bar give divers somewhere to dry out and talk through the last dive. The dhoni carries the wet equipment and compressor work away from the living spaces, which makes the return to the Mariana feel cleaner and calmer. On the final day, the programme includes one morning dive before the boat returns to harbour around noon. Then the deck changes from dive base to departure point.

Meals are served as full board, with buffet service, local cooking and snacks available through the day. Vegetarian and vegan choices are available, and the bar carries beer and wine; non-alcoholic drinks are separate from the included drinking water, tea and coffee. Outdoor dining and occasional beach barbecues give the meals a Maldivian setting instead of keeping every plate inside the salon. Food matters on a dive boat because the table is where the day is reset: divers return hungry, compare what passed the reef, eat, and get ready to do it again. The food score of 9.0 is the strongest of the boat's published ratings, which fits a trip where meals are one of the main pauses between dives.

The Mariana's nine cabins are air-conditioned and have private bathrooms, so the basic recovery after a dive is simple: rinse off, cool down and sleep without sharing the space. Lower-deck cabins have the more enclosed, traditional boat feel; the upper-deck cabins bring more light and panoramic sea views. Cabin choices include lower-deck single, lower-deck double or twin, upper-deck double or twin and upper-deck double. The main deck connects the salon, bar and dining areas, while the upper deck gives the boat a more open place to sit. There is no suggestion that these are oversized hotel rooms. They are working liveaboard cabins, made comfortable by cleanliness, daily housekeeping, air conditioning and private bathrooms. At night, the useful luxury is quiet recovery between dives and the ability to close the door on the day.

Departures and returns are in Malé, with the recorded routes running Malé to Malé. Airport transfers are included: on arrival, an EcoPro Divers representative meets guests after baggage claim at the international airport, identifiable by the company and boat name. The earliest boat transfer is around noon, and later arrivals are handled according to flight times, with possible waiting for group transfers. Arriving in Malé the night before is the sensible way to remove flight-delay pressure from embarkation.

The boat produces drinking water through a reverse-osmosis water maker and serves it from a dispenser, reducing reliance on single-use bottles. EcoPro Divers also uses reef-safe products on board. The operator pairs island visits with beach clean-ups, bringing a bag of rubbish back from each shore visit. These are modest measures, but they are concrete parts of how the Mariana's trips are run.
