Hello,
That is quite a photo, quite a shock to see the bow cut off but the rest remaining. I wonder why this was done? It may be due to corrosion and the effects of being outside for many years, but it is unclear why the bow would suffer much more than the rest of the boat.
Presumably the bow was rebuilt with new plating and the replacement was done without adherence to detail. For example the boat presently has no vents around or above the torpedo doors. They mustn't have bothered to cut the vents when replacing the bow plating, either because it wasn't a good replacement job. Or they wanted this area deliberately sealed up to help prevent future corrosion.
Cheers,
Dougie
