I used to have a Sea Ranger 65. Sea rangers were built from 38-72 ft first by C&L marine then later by King Yachts. I loved my Sea Ranger, one of the trait's was to have a little more beam than similar length boats for there size.
If you go to Rick Obeys (broker website) Rick Obey and Associates, leader in yacht and ship brokerage community
he featured Sea Rangers in his Power boat guide that you can download for free! You should be able to match it to the photos or dimensions etc. If I can help further P.M. me . I could send you the relevant pages from this years guide I downloaded.
