About Nautidiver: Dublin Bay Diving, Boat Charters & Scuba Courses

Founded in 2012, Nauti Diver is a dedicated, diver led scuba diving centre and coastal charter operator based out of Dún Laoghaire Coal Harbour. Bringing extensive global dive experience home to the Irish Sea, we provide internationally recognised diver training, an active diving community, and regular boat charters.   

Whether you are taking your first breaths underwater or advancing to deep wrecks, our focus is on safety, small group sizes, modern instruction, and building genuine diver confidence.   

Why Dive with Nauti Diver:

Personalised, Small-Group Training (Max 4:1): We strictly cap student-to-instructor ratios to a maximum of 4:1, ensuring you receive dedicated attention without ever feeling lost in a crowd.   

SDI & PADI Certifications: We primarily recommend and teach SDI (Scuba Diving International) for its modern curriculum and flexible eLearning, but we also gladly teach PADI courses upon request.   

High-End, Premium Rental Gear: Train and explore using top-tier equipment, including brand-new XDeep wing systems, Apeks regulators, and Aqua Lung Legend regulators for smooth, effortless breathing in temperate waters.

Convenient South Dublin Pool Sessions: Confined water skills are mastered in pool facilities at DLR Leisure Monkstown (Tuesdays) and St. Columba’s College (Wednesdays) before heading into open water.
