Hi Bernadette,
The sales facility on this site is only for regular contributors I'm afraid.
As far as your model is concerned, if it is really high quality then an auction site might accept it but otherwise model boats do not tend to fetch very high prices at the moment. Your best bet would be to list it on Ebay with photos to see what degree of interest there is.
By all means upload a couple of photos and we can then see which would be the best route to go down. You will need to either create an album first or post a link to a photo sharing website. (See our FAQ at the bottom right of the page section for further advice).
Regards,
Colin
