Defiance hull inspection November 2004
Starboard side aft quarter keep plating: There is a outward distortion of the keel plating extending from the aft engine room bulkhead to the next station a distance of roughly 6 or 7 feet long with the maximum % of the keel height reaching perhaps 70% at the widest point of the distortion. The maximum outward distortion is perhaps 0.5 to 0.75�.
After sounding the hull thickness in the questioned area has proved to be of more than adequate thickness, however the concern was as to how the water entered the keel in the first place.
It took me a couple of days to click in as I did a good stint of bilge diving until I remembered what I had originally taken to be a abandoned bilge pump was in fact a standpipe to the keel left open during construction to provide a way to ballast the hull after the keel was attached.
There is little deterioration in the standpipe and the cure is as easy as a proper 2 1/2" black irom pipe cap. Nor should I be shocked at the pure stupidity of the fool who came up with this ingenous system.
