Here is a link to the Seafarer Research Center site. It has some original data for the Seafarer 38. I have a 1971 Seafarer 31 Yawl. It is great looking with a very solid hull and deck. Some of the interior materials leave much to be desired, and it's narrow beam makes things a little tight. But we love it. I wish you luck with the 38 if you decide to get it.
