Tata Steel Sailing Club (Clwb Hwylio Dur Tata) is situated on Eglwys Nunydd Reservoir at Margam, near Port Talbot, with convenient access from the M4 motorway.

Founded in 1953, the club is based on a sizeable freshwater lake approximately one mile long by half a mile wide, offering conditions well suited to dinghy racing, training, and windsurfing.

Swansea University Sailing Club and Sea Scouts also form active parts of the membership. Access to the reservoir is controlled via a combination lock, with the code provided to paid-up members.

Visitors or prospective members should contact the clubhouse by phone, and a member will come to the gate to grant entry. The club is recognised by the RYA as both a club and a training centre.
