I just bought an O'Day Day Sailer, HIN 20705, model # 3780. The title that came with it says it is a "1969 O'Day Sailor V 17'-0"." Being new to the DS world, I'm not sure the title is correct. And, the guy I bought it from wasn't very helpful with instructions on rigging it. I've downloaded the original DS rigging instructions but I think this boat has been modified somewhat and the rigging isn't original. The boat was previously docked at Lake Hefner according to a sticker on the side so I'm assuming someone there owned and sailed it there. For the past four years or so, it's belonged to someone else who only sailed it a few times on Lake Thunderbird, near Norman.
Can anyone help me figure out exactly what I have from the HIN? (DS I, II, III)
Are there some websites that will show me some different riggings used on that model? Some of the diagrams I've looked at are confusing.
