Why We Cap Boat Trips at 18 Divers

Thinking of diving the Medes Islands but worried about crowded boats? Here’s exactly why we cap boat trips at 18 divers: to maximize comfort on deck, keep things calm underwater, and uphold our commitment to RESPECTFUL diving in the Parc Natural del Montgrí, les Illes Medes i el Baix Ter. You’ll learn how our small-group policy improves your experience, supports marine protection, and streamlines every step—from gearing up to the final rinse at the campsite.

The Short Answer

What “18 Divers” Means on Maria Mir

Our boat, Maria Mir, is authorized for 25 passengers, but we choose to cap each trip at 18 divers. The goal is simple: more space, smoother entries, and a quieter, more relaxed dive.

Why it Matters

The cap creates a better rhythm on deck and in the water. Boarding is calmer, briefings are clearer, and entries are unhurried. Underwater, fewer bubbles and bodies means less distraction and a more natural encounter with marine life.

Comfort and Calm: Designed Around Your Experience

We limit the number of divers per trip so you can dive quietly and comfortably—on deck and underwater. Then we split into two or three small groups, each led by one of us. The result:

RESPECTFUL Diving in a Protected Marine Area

We call it RESPECTFUL diving—care for the environment and care for divers. Since 1996, we’ve offered diving in L’Estartit and the Montgrí–Medes–Baix Ter Natural Park with peace of mind, good service, and professionalism. Limiting each trip to 18 divers is central to that ethos.

Low Impact, High Awareness

In a protected marine environment, smaller groups help minimize contact with the seabed and reduce silt disturbance—both widely recognized best practices for preserving visibility and fragile habitats. We reinforce this approach in our SSI-based theoretical sessions and with training that emphasizes buoyancy control, so divers avoid unintentional contact with the bottom or the reef.

Safety and Seamless Logistics

A clear safety benefit of smaller loads is situational awareness—for divers and guides alike. With 18 divers split into two or three groups, guides can better monitor air, depth, and spacing.
