for the first, sorry for my awful "schoolenglish".
I´m from the coast of the northsea in germany and i bought an oday22.
Now we have some trouble with the old owner and i have to find out the age of our boat for one thing. He says it is build in 1978. The boat has no "window" in the front, you know? And the serialnumber is "XDYJ07250573". Can somebody help us?
