Hi all,
Asked to look at a cabin top that was dislodged by a crane and found a great example of what rot can do. this is an old boat- about 50 years and at some time in the 70's or 80's, someone hit the superstructure with a chopper gun. The cabin top beams which extended out from the cabin sides had been encased in glass. A number of fitting holes in the cabin top had allowed water in and it had migrated through the ply and saturated the structure. As I was pulling it up today I was amazed at how 4" x 2 1/2" beams had been turned to mush. The ply cabin sides were the same. the glass is around 3/16" thick and no one was the wiser until the incident bared what was underneath.
The beam shelf is about 6' x 3" and has to be replaced as well as at least half the port cabin side.
Main cause of all of this was a hole cut for an antenna to stick through the roof and the sides of the hole were left bare.
Have a look at these pics.

In this pic, the cavity used to house a healthy cabin top beam. Now all that is left is a few crumbs and the glass shell that surrounded it.
Back tomorrow to keep cutting away until I find some sound wood!
Anyone else got some good rot pics you would like to post???
