I see a stripping party in your future.
Until you get the boat 100% bare, I couldnt judge whether to keep after it or scrap it. Based on the pix, it is likely to need extensive work, see ClassicCats SS rebuild.
Or Dozers work removing a keel strip on 1 of his projects.
Limited pix, remotely via the internet, it can be extremely difficult to assess some damage.
A few pin holes or hundreds spread across a 3SqFt area versus a 10SqFt area.
Can it be fixed? Absolutely. Simply takes time and money and a pile of want to. The last 2 are often what dictates a projects completion.
Ask about the peoject rigs around my boat yard. Rarely have the time, usually short on the money, so I'm big on patience, waiting to dig in to them. What I have most is the want to.
