I have a E29, I noticed one of the plate screws coming out of the mast cable, (don't know all the right words here,) where the rigging that holds the mast up attaches to the boat, anyway, it was a wood screw, shouldn't it be bolts through the cabin top? Seem kinda flimsy to me, I am sure it is factory installed. There are 3 on each side, hope you know what I mean here. Thanks Bobg
