You were right. The first 3 letters stand for oday. The letter b stands for javelin. The four digits following are the class number. These four will be on the sail. The next three start with the letter m and is followed by 2 numbers which is the year. Our boat was made in 76. The very last character is the month it was made in. Ours is C which says that it was made in march. Thank you for taking the time to respond! She just ordered the sails.
Now I have to get the parts for my motor and finish rebuilding the engine. I also have to do a little gel coat work. I am excited though. I see light at the end of the tunnel!!!!
