Volvo Ocean Race, Torture Boats, Comment 5

All of us who sail have, at one time or another, experienced foils that, at speed, hum or sing. I never had a singing foil that affected my day out pleasure boating. But VOR leaders Ericsson 4 have a rudder that day in, day out, 24/7, just shrieked.



Would this be equivalent of hearing nails on a blackboard 24/7?
