Lets see $3500 for boat $800 for survey $10,000 for materials, 3 years labor, ???? yard fees, unknown problems. Final value $8,000/10,000. You better love it. This is NOT a glass boat. When you get done you start over. TAKE YOUR HIT AND RUN!!!!
60 years of boating here. Wood, steel, fiberglass, aluminum. First boat was a freezer liner. 3 Chris Crafts and an Owens before I learned my lesson.
A planked Pacemaker is the ultimate in required maintenance. Especially if you have to pull them every winter.
