About Hammerhead Cozumel
Hammerhead Cozumel runs a single boat, named the Hammerhead, out of a small SSI Instructor Training Center on the island's south coastal highway. Trips stay small and personal: reviewers spanning more than two years keep naming the same two staff members, dive instructor Juan Vega and Customer Care Specialist Claudia, independently of each other. Diving focuses on Palancar Reef and Santa Rosa Wall, with the shallower El Cielo reserved for the shop's snorkeling trips.
A specific strength is scheduling around cruise-ship port days. Several reviews describe last-minute or email-only bookings fit around a ship's arrival and departure window, and the cancellation policy separately addresses cruise-related cancellations as distinct from weather cancellations. Certification runs to SSI Open Water and Advanced Open Water; Discover Scuba covers a first dive for anyone without a certification. Captain Giovani and deckhand Master Gio round out the crew, and Claudia's on-boat lunches turn up repeatedly in reviews as a specific, unprompted highlight.
What divers say
At least ten different reviewers, writing independently between March 2024 and August 2026, name the same two people, Juan and Claudia, not a rotating cast. Multiple reviewers describe personal, small-group trips, one contrasting the experience directly with a large charter-boat operation elsewhere. Several single out the lunches Claudia prepares onboard as praise distinct from the diving itself, not a passing courtesy. Others describe the shop fitting a dive around a cruise ship's port day on short notice, sometimes arranged by email the same week. No complaint pattern surfaces across the reviews available for this page, which sits at 4.9 from 73 Google ratings.

Frequently Asked Questions
Can I book a dive with Hammerhead Cozumel around a cruise-ship stop?▾
Yes. Several reviews describe trips fit around a ship's arrival and departure window on short notice, sometimes arranged the same week by email. The cancellation policy also treats cruise-related cancellations separately from weather cancellations.
How big are the dive groups?▾
Small. The shop runs a single boat, the Hammerhead, and reviewers consistently describe personal, small-group trips instead of a large charter-boat experience.
What is the difference between the SSI Open Water and Advanced Open Water courses here?▾
Open Water combines online theory, confined-water sessions and four ocean dives, capped at the standard 18-metre certification depth. Advanced Open Water adds five dives built around mandatory Deep and Navigation modules, plus three electives chosen from Buoyancy, Drift, Wreck, Night, Search and Recovery, or Underwater Photo/Video.
Is Nitrox available?▾
Yes, on request, along with extra tanks. One exchange asked specifically for BCDs, regulators and Nitrox and got a detailed, specific answer, not a generic yes.
What does the Discover Scuba trip include?▾
It is priced and sold as a first-time scuba experience for anyone without a certification, a separate product from the shop's Snorkeling Trips option for non-divers.
Who will I be diving with?▾
The same two names recur across reviews spanning more than two years: dive instructor Juan Vega and Customer Care Specialist Claudia, alongside captain Giovani and deckhand Master Gio.
Are multi-day dive packages available?▾
Yes, quoted directly by the shop instead of posted online as a fixed price.
