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.
PLEASE keep in mind that acetone can SOFTEN and can potentially DESTROY any bonding you have left between the balsa and the glass skins. I have seen the results of both drill & fill and vacuum dried/filled decks. I can assure you it is a band-aid at best. If the boat was hand laid the resin usually just rides the kerfs but the acetone has already softened the bond so you really get...well .. a high tech solution that really solves little... You can almost always excavate and do it right in less time. You still have to fix all your drill holes anyway so paint or gelcoat are going to happen either way. I often wonder if any of these yards charging an arm & leg for these "solutions" ever have a cut away section of deck they can show a customer? I know why they don't...
