Scuba Mau

Scuba Mau runs boat dives out of Marina Caleta, on Cozumel's south side, positioning the departure point as faster access to the southern reefs than a shop based downtown. The business is owned and run by Mau Torelli, who learned to dive as a child from his father and has more than 30 years in the water since. Groups are capped at six divers per guide, a policy the shop's own site describes as deliberately avoiding "cattle boats", and the crew is small and named: captain Rafael Poot, dive masters Alejandro Haro, Rafael Romero and Jesus de la Cruz, instructor Sandy Alloza, and deckhand Alejandro Salgado.

Diving is entirely boat-based aboard TAU, a twin-engine boat built for small groups and privately owned by Torelli. The standard trip is a two-tank morning dive, 8:30 am to 1 pm, with fresh fruit, snacks and purified water at the surface interval. Courses run from Discover Scuba Diving through Divemaster, taught in Spanish, English, French or German, and endorsed by both PADI and SSI. Rental gear, air and Nitrox tanks are available by the set or the item, and the shop also runs snorkel trips to two reef sites. Multi-day dive packages and dive-and-stay logistics with nearby hotels, arranged as booking help rather than a lodging product of its own, round out an otherwise straightforward, family-run boat operation.

Reviews name the same people again and again: captain Rafael's sharp eye for spotting divers and marine life underwater, dive master Jesus's thorough, easy-to-follow briefings, and instructor Sandy's patience teaching an Advanced Open Water course. Divers repeatedly describe being treated like family, and several mention meeting other repeat customers on the boat. Small groups come up consistently: several reviewers report four or five divers with a guide, below the boat's stated maximum of six. Safety is a specific, recurring theme rather than a general claim: in-water checks on buoyancy and ear-clearing, thorough pre-dive briefings, and attention to the current and drift conditions typical of Cozumel's southern sites. No complaint pattern surfaces across the reviews available for this page.
