Newcastle Yacht Club was formed in 1962 and sits beside the harbour at the foot of the Mourne Mountains, overlooking Dundrum Bay in Northern Ireland.

The clubhouse enjoys direct water access at all states of the tide, with sweeping views across the bay toward the mountains.

The harbour can accommodate visiting bilge-keel yachts that can take the ground, with access to the outer quays for vessels of around 1. 0 m draft roughly three hours either side of high water. There is no dedicated visitors' berth.

The club runs racing on Thursday evenings and Sunday afternoons through the sailing season, and visiting crews are welcome to use the facilities when the club is open.
