How to stop a singing mast?
From a leading spar manufacturers owners manual...
"Vibration can occur in any aluminium mast of normal design. With wind coming from approximately abeam at speeds of 4–12 knots the mast oscillates longitudinally at a rate of 3–6 cycles per second. As an optional item an ”anti-vibration strip” is available for hoisting in the integral sail groove at the aft face of the mast to prevent vibration starting. It will also reduce wind noise."
