The last few years the O'Days may have been built by Pearson for O'Day/Bangor Punta. BO is whom owned, Oday, Cal, ranger and at least Jeanneau in the 80's before all but Jeanneau went down. I would not be suprised of the French gvmnt had something to do with Jeanneau not going down, and getting picked up quickly but another outfit, then about 10 yrs later getting sold to Group Beneteau.
Pearson is or has been a builder of J-Boats too. So whom is to say these are not issues with the factory, "BUT" issues that will not show up for 20'ish yrs or there abouts too. Altho the J-Boats have been 5-10 or so yrs old IIRC, maybe a bit older.
If my mid 80s Jeanneau is built like the 80's O'Day, it would and does make me look at the keel as best as one can when she is hauled every yr or two.
I Heart O'Days may have some info on whom built what odays in what yrs, along with model numbers.
