Spars
It seems strange to me that O'Day would use two different make spars on the same boat, but I suppose that it's possible. My 222 has Z-Spar for mast and boom, along with Schaeffer hardware through out, but I do know that they also used Dwyer spars on their West coast O'day boats. Maybe something happened to the original boom and they replaced it with the Kenyon. I'm not even sure if Rudy Nickerson of D&R Marine would know about this, as he had worked at the O'Day factory in Fall River Ma. at one time.
