The Welsh Harp Sailing Association (WHSA) is an umbrella organisation based at Birchen Grove, NW9, on the shore of Brent Reservoir in North West London.

It brings together several separate clubs and leases the reservoir from the Canal & River Trust to oversee all water-based sports and leisure activities on the water.

Member clubs cover a range of disciplines, including dinghy sailing, windsurfing, canoeing, and water-safety training.

The association's roots stretch back to the post-war era, when company and local sailing clubs gradually formed on the reservoir before consolidating under the WHSA banner.

Today it serves as the collective body coordinating access to 125 acres of open water just a few miles from central London.
