Can Anyone Identify this little Trailer-Sailor ? ?

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

".
