Some great replys thank you.
I agree, if someone travels some distance and know what they are looking at then they are most likely genuine and as Nick says, you easily form your own judgement.
Can't dissagree with Lakesailor, there are some awful examples of pictures where ever you see things for sale. You need to take good quality and lots of them so that someone can get a feel for the boat and see everywhere in detail.
If you want to see how it should be done just look at Jonic's 'ahem' post, good pictures and you can almost walk around the boat.
First problem for me will be - I have to clean the boat before I can take some pictures!!!
