The Royal South Australian Yacht Squadron (RSAYS) is a long-established yacht club situated on the southern shore of the Port River at Outer Harbor, roughly 30 minutes north of Adelaide's CBD.

Founded in 1869 as the South Australian Yacht Club, it is one of the oldest sailing organisations in the state. The club's marina accommodates around 252 berths ranging from 10 to 30 metres, with power and water utilities.

Hard stands are available for trailable vessels, and dry stands house sport boats on jinkers. The Squadron also maintains moorings at several regional locations for members.

RSAYS runs an active sailing calendar including inshore and offshore races, twilight racing, and a women's series, alongside social events. The facility serves as a practical access point to the Port River and beyond.
