Chaps,

I have not had this problem at all. But I do keep the Schlegle (sp) tape in very good order and replace as required. I have also removed the rubber that holds the plate in place as I found that if you Schlegle tape from Laser www.lasersailing.com you do not need it to keep the plates in position as the tape is grippy without holding the plate very tight to the side of the dagger board case - this helped as I hit Thirslet spit here hard with the kite up and the plates actually came up a few inches (which was nice ) and no damage to the underside of the boat at all, just put the rudders back down and carried on down the track.
