When is a let called in beach tennis?

A let is called on a serve when the ball clips the net cord and lands in the correct service box, or when the receiver is not ready. The serve is replayed without penalty. Lets are not called on shots during a rally.

Full Explanation

Per ITF Beach Tennis Rules Rule 7.8, a let is called during service when: (1) the served ball touches the net, strap, or band and then lands in the correct service box or on the line bounding the service box; (2) the served ball touches the net and then touches the receiver or anything the receiver wears or carries before hitting the ground; or (3) a service is delivered when the receiver is not ready. In all these cases, the serve is retaken without penalty and the server's attempt count (first or second serve) does not change. During rallies, a net cord that lands in the opponent's court is in play; there is no let called. Under Rule 12, an involuntary hindrance during a rally may also result in a let (the point being replayed).
