Hi fibersnap,
I have one of these boards tucked away somewhere. They are a very friendly board, rail upwind in a very balanced way and are fast off the wind. The board looks to be in very good condition from the photos. The centreboard isn't carbon fibre (just black paint over glass) but works well with the board. I have used a weed fin in the board and it works just fine on all points of sailing. The only downside of this board is that the tail is quite narrow, so light wind racing performance is geared towards lightweights. Back in their day (late 80,s early 90's) they were the board to be on!
Have a close look at the gasket/slot flusher (the rubber tears off the plastic attachment) and the mast track pedal (the black pedal cracks at the pivot point). Parts are rare!
The price (converted to $AUS!) seems reasonable.
I hope this helps.
