I'll let you know if it works!
I'll also let you know if it does not work. I was told that using the Hi-Vac system that 99-percent of the moisture will be removed, but it's not something that takes a few hours--it takes days of constant high-vacuum suctioning before the acetone is injected for the completion of the drying process. At today's labor prices, the cost of replacing the core and then re-doing the deck surfaces would likely be higher than the cost of the boat. Hey, if I get another 10 years out of this old tub, and I don't loose too many of my body parts in the next decade, I'll be more than happy with the repair. A decade from now both me and the boat will be ready for the scrap yard.
