Just realiezed I never revisited this thread. I did pass that boat up, the seller made that decision easy when they would not reduce the price to reflect the cost of the repair. I bought another Cat 30 three weeks later. She was a few years older, and had tiller steering and A4 compare to the other's wheel steering and diesel. BUT she had had the mast, boom, and ALL standing rigging replaced less than two years ago.
BTW, the last time I looked (in the last 2 weeks), the other Cat was still on CL.
