J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Hull Drying, How did it get wet?

Has anyone tried using the "HotVac" system for drying a wet hull? I ran across the information using an ask.com search. The link is; http://www.hotvac.com/
A local yard here in the Portland Oregon area has one and claims it will dry a wet area on a hull or deck in 7 to 10 days.
Just like the vacuum bag process except constant, even heat applied at about 100c.
