Hornsea Sailing Club is based on Hornsea Mere, Yorkshire's largest natural lake and a designated Site of Special Scientific Interest and Special Protection Area.

The club has operated on the mere since 1946, with access to more than 250 acres of navigable water. The mere's maximum depth of just 2. 5 metres makes it particularly well suited to beginner sailors.

The club offers a range of membership options and hosts competitive events including dinghy racing.

It serves as one of the primary access points for sailing on Hornsea Mere, alongside other water-based activities such as rowing and boat trips available at the site.
