I noticed a Sun Fish hull (the hardware etc may in storage there) at the boat rental store on Stock Island just before the bridge to Key West. I'm headed back there in a couple of weeks and will check it out for you.
The boat looked to be in pretty good shape.
Looking for someone interested in sailing in Key West this winter. If you get a boat, let me know. I'm no "racer" or anything like that. Just a guy that loves to sail around not too far out or off the beaten track.
