I have a 1971 P26 that had 3 inches of water in the bilge when I bought it. THe bottom of the compression posts in the cabin doorway are grey and I am concerned they have been compressed from being soaked for 2-3 years while supporting the mast. Can anyone tell me what the height of the posts should be? Further support for the idea that they have compressed is that the doors to the V-berth no longer fit in their tracks suggesting the cabin roof in the area of the mast has been compressed. Any help or suggestions would be appreciated. Any experience replacing P26 compression posts would also be helpful.Mike
