Well that about it for the demolition stage.
The tank was bedded in with filler
, and required a bit of TLF with the crow bar.
I am going to try to peel the tube tape off the inside of the hull and drop the tubes outside and below to keep them out of the way. If that fails, I will remove them completly.
So why did it happen?
Cheap build spec. is mostly to blame.
As far as I can tell, the port deck bearer was contaminated with rot before building. These bearers wer secured to the stringers with a mixture of St/St screws and mild steel screws (they may have been very poor quality St/St).
The soft screws rusted away over time allowing the rot to escape through the resultant holes. The floor was not well supported and flexed, resulting in the resin coat on the underside to crack. The rot then entered the floor through these cracks.
