TYCA is an association of sailing clubs around the Tay estuary and drainage basin, and the surrounding coast. It includes clubs whose main interest is cruising as well as those with more competitive ideals, clubs which sail dinghies, keelboats, sailboards and catamarans.

The purpose of TYCA is to improve communication and co-operation between member clubs, to publicise each others events and try to prevent major conflicts in the dates of club events.
