Check compression post
Pete,Last spring we bought a '77 H30 and had it surveyed, with no major problems showing up. As it turns out the surveyor totally missed a problem with the compression post. The I-beam above the keel is OK and so is the plywood on top of the I-beam, but the mast is sinking, so either the top of the compression post is rotting or the basa core in the cabin top below the mast is saturated. An easy way to detect the problem is to check the alignment of the door to the head. Close the door and see how it aligns vertically on the starboard side. It the gap is not the same from top to bottom, there might be a problem.Otherwise, it is a great boat.Good Luck!Karl
