Happy New Year from Pennsylvania, USA.....

Please help I.D. this ex-navy vessel.  I have contacted the image owner (he had no other info) for permission to post it to help I.D. her.
Photo taken 7+ years ago in waterways near Sydney Australia.  All we know is it is a former naval vessel purchased/converted for private use.
Who's navy did she serve?  Class? Purpose?

MANY MANY THANKS!!!

Hi,

The ship picture could be the ex HMAS RUSCHCUTTER since we see two rectangular windows on the top of the hull when her sister HMAS SHOALWATER has a windowless hull. Check this :

Seems she's making her rounds.....

Whoever reads this - How risky/off-putting is it to have those twin hulls made of fiberglass???  More or less of a nuisance headache than steel or aluminum?
