Unless I open something up, you/I can't see anything other than 2 big cracks about 6" long going from opposite sides of the mast on the cabin top; can't see anything even if you peel back the liner.
I did get an interesting suggestion to put two 1/4 inch aluminum plates along opposite sides of the compression post.
This still leaves open the question of whether there is any damage to the plate or whatever Seidelmann put at the base of the mast and above the compression post (that goes down to the keel).
Thanks for your interest.
IF, IF I have to rebuild the step how does that happen? I'm assuming the mast has to be lifted up first? then cut open the cabin top, rebuild the plate, then put mast down and reglass the top?
