Graham, your enthusiasm has taken charge of you. It would cost 5 times as much to fix it up to what it might be worth. You would be lucky to get $4-5000 for it in reasonable nick.
It is invariably better to buy a boat somebody else has spent the money on. I like ebay but it seems to be riddled with rubbish that should be given a dignified burial at sea or overpriced Buy it now listings.
If I was to buy it, it would be as a daysailer/ racer for Jervis Bay. Would not care how much it would sell for! I always watch what Jonathon sells on eBay. Has some interesting stuff at times. Just don't have much spare time, flat out with projects. Got to spend all that money before I peg out!
