The boat had been full of rainwater and all of the wood inside was rotten. I didn't feel like I could do the job right without better access to all the interior space.
I wouldn't try that on a bigger boat, but for this one, I'm glad I did. I would never had been able to reach some of the areas to clean and paint otherwise. Also, I couldn't patch the underside of the deck the way I wanted to if I had tried to do it inside the boat working over my head. Gravity is a big help when working with epoxy
Like you I wanted the learning experience, and I definitely got that. Some stuff I did wrong out of ignorance and had to do over, and there are still some things I'm gonna change, but overall I got pretty lucky for a first time boat resurrector.
