berny Posted April 25, 2004 Report Share Posted April 25, 2004 Ok, does anyone know why my foils hum? One rudder and one d/board get a real sing song going as soon as the boat reaches a certain speed. It can't be fast and I'd like to eliminate it because it's annoying but I'm at loose end having checked the alignment and I've also tried fairing but no result. I have a suspicion it might be that the gelcoat isn't bonded to the glass laminate in some places. That's about all I can think of as being the culprit. Any other ideas?
