Bringing Scuba Diving to North County Dublin Since 1983

Portmarnock Sub-Aqua Club (PSAC) was founded in 1983 with the aim of bringing the sport of Scuba Diving to North County Dublin. We are a friendly, welcoming club with over 30 members spanning a wide age profile and an even male/female split. We are actively looking for new members so if you're considering Scuba, please get in touch. We are open to snorkelers over 13 and divers over 16.
From training to adventure, PSAC offers a wide range of activities for divers of all levels.
We organise weekend dive trips away as well as week-long trips to varied locations around the Irish Coast. We also dive as a club around the Mediterranean, Red Sea, Canary Islands, and colder waters off Scotland and Norway.
We offer weekly diving and snorkelling in and around Dublin bay from April to October every Sunday and most Thursday nights off Howth. Diving in Dublin is normally around Ireland Eye and Lambay Island, but occasionally also visiting advanced dive sites. Snorkelling tends to be to Ireland Eye and around Howth.
Weekly training sessions at Portmarnock Sports and Leisure Centre for both diving skills and checking gear. There are around some hard-core fitness junkies who take a lane and push against the clock. Most the pool is more leisurely, and the hot sauna is a welcome wind-down.
We start beginner training in March and November and aim to get divers to their 1* or Open Water level in that season. All our training is ISO accredited, highlighting professionalism, instruction skills and individual development.
Our skill levels allow us to offer rescue boat cover for some important events throughout the year. These include the Dublin Pride parade and providing boat cover on the Boyne outside Slane Castle during concerts.
On the environmental front, we have an "Dive against Debris" underwater clean up event planned for later in the summer.
We have 4 Rib boats in our purpose built boat house. New M1 Rib (6.5 meters), M5 (6 meters), M6 (5 meter rib) and a 4 person rescue boat(45 HP engine) called Barbie which we use for Slane concert and Dublin Pride river cover, being easy to tow with a shallow bottom.
We also have the latest Air and Nitrox Bottle filling station (commissioned in 2026), along with an assortment of buoys, diving lines and rescue equipment.
