History of the INSS

Set up by Alistair Rumball in 1978, the sailing school had very humble beginnings, with the original clubhouse situated on the first floor of what is now a charity shop on Dun Laoghaire's main street. Through the late 1970s and 1980s, the business began to establish a foothold, and Alistair's late brother Arthur set up the chandler Viking Marine during this period, which he ran until selling on to its present owners in 1999.

In 1991, the Irish National Sailing School relocated to its current premises at the foot of the West Pier. Throughout the 1990s the business continued to build on its reputation and became the training institution of choice for budding sailors. The 2000s saw the business break barriers - firstly by introducing more people to the water than any other organisation, and secondly pioneering low-cost course fees, thereby rubbishing the assertion that sailing is an expensive sport.
