My Typhoon is showing signs of deck compression (raised bumps near the chainplates). I know the common solution is to install a compression post in the cabin. I'm a little confused about the after affects. Should the post raise the cabin top to the point that the bumps are no longer there? Will the cabin top be that flexible or could it cause cracking around the chainplates? How far does one ususally raise the cabin top?
Any comments or suggestions would be appreciated.
Thanks.

My interior measurement from the forward end of the cabin sole to the middle of the mast step bolts on the overhead was 38" before I stepped the mast (1976 Weekender). Now it is about 36". I will be installing an oak compression post! I do not suffer from the "raised bumps" at the chainplates. I would unstep the mast and take all the pressure off the cabintop for a week of warm weather. Measure before and after, see what you get. If there is a substantial difference, fit the post then step the mast. If not, then I don't know what to tell you! But I suppose you could put a small amount of pressure with the post and step the mast and tune the rig. I would not try to force it up much! Just fit the post so that it will not sag any more and tune the rig. After some sailing, check it again. If your rigging gets slack after you had tightened it, I bet either your cabin (and floor if post is in) is sagging or the gunwhales are a-lifting. Good luck, I'll let you know how mine goes.
