Hi all, This boat is approx.5.25 m long (almost 18 Ft); has a retractable swing-keel. I believe it was first launced in Australia (WA). This is all I know. I recently purchased this little beauty and when I get finished with her, she'l be better than the day she was built ! I really appreciate any help you could give me. Please e-mail me at: jaapklasema@gmail.com BTW; I am located on the Easter Seaboard of Thailand, right in "The G ulf ".
