Hello Jim:
Being from California, I can't imagine the frigid conditions that you (and the millions and millions of others along the midwest and Eastern Seaboard) must be enduring right now. Our daily 60-70F issue, other than virtually no rain, is that every day wind is zilch. Winter normally is a low wind period, but we do have pulses that get us out on the water. But very few this year. Because of the strong tidal currents on San Francisco Bay, even a say 5knt wind is not sufficient for a enjoyable sail other than futzing around back-and-forth in the channel. A petty situation compared to your wondering if your deep freeze and maybe some water wisking into the FRP will crack your hull or deck!
I see your point about contacting the Craigslist seller. But if I might suggest, let me eMail the Seller to introduce myself as a fellow Cherubini owner and to suggest that he/she be aware of the Cherubini forum and database. He should know about as a selling reference because everything on SBO forum would certainly encourage a prospective buyer who is interested in a 1980's era boat to put the 37's high on the list.
Regarding your observation about including 36's: Yes I have thought about also. Really though, the 37's are different in many respects. But for other elements, we do share construction similarities. I think very few 36's were made by Hunter compared to the 37's. However a simple "demarcation" on your database between 36 and 37 would serve. Under your guidance, I would be happy to spearhead a Cherubini 36 effort.
While at it: Others reading for Cherubini 33, 30, 27 and 25 willing to start a database for your models?
I have often wondered about the fate of my boat when say 10-15 years from now I lose day-to-day interest or become ill or injured. Or what my daughter will need to deal with if I become unexpectedly dead. First choice is that I would like that the boat be kept alive and will attempt to sell. But depending on the conditions, rather than anticipating some new buyer will return my "investment", which is diminished by $500-600 every month berthing/insurance/maintenance/property tax cost, at some point the least stressful solution might the demolition dock. But 10-15 years from now, and a whole new crop of sailors, also probably will not be much vintage premium left.
