It all began with this thought: Just as our fathers fantasized about the woodies of their youth — Gar Woods, Chris-Crafts, Hackers, etc. — we fifty-somethings dream in fiberglass — old Bertrams, Formulas, Donzis and the like. For some these dreams are harmless. However, for others they become a nightmare, and sufferers feel compelled to "invest." Question: Would blowing $100,000 on the restoration of, say, a classic 20-foot Bertram Baron seem odd? Don't answer. Instead, let me introduce you to Cadillac McDaniel. I thought I had a problem with boats — Cadillac is truly sick.
