DS III
The DS III is distinguished most easily from the other two by a smaller cuddy opening and a higher back end. It is not class legal, like the other two, because the hull is different.DS I were manufactured from 1957 through to 1997 excepting the years 73, 75 to 80, and 1993.DS II were manufactured from 1971 to 86, and I believe are still being manufactured. (My data ends for all models in 1997)The DS III were built from 87 to 92I have used web pictures and pictures sent to me by others, as these pictures best show the differences between the models. I cannot take credit for these pictures, but am thankful for others. I have used these pictures without their specific permission.
