I've started a SketchUp model of the Dolphin, but I think I need to redo much of what I have. The rear transom is too wide. But, this should look familiar!
I think the overall profile is close (I traced a photograph) and the scale is pretty close -- the 1997 Geo Metro uses 13" rims, right? Or are they 14"? The overall length of the model is 16' 9 1/2" which seems to be pretty close. I'm hoping to hear back from Dave Cloud with some hard dimensions, and higher resolution photos.
