I recently acquired a this fiberglass boat which has has been in my family since new. Was sold and registered in CT since new as a 1964 15ft Duratech Sabre serial # 41566. The problem is Duratech never manufactured any fiberglass boats after 1961 according to published production information. This boat is almost identical to a Glass Magic Nymph sold in 1960. Data plate and Duratech badging are are original and correct. Does anyone have an explanation or know how to access Duratech records? I want to get a motor correct for the age of the boat, which I believe may be about 1960 or earlier.
