If you were a gambling man I'd suggest sticking the lot on red at your nearest online roulette!
Having secured double that amount, do not be tempted to go again for a Swan - your path is now clear, a nice Nicholson 35 for £40K. HTH.
There was a Fastnet for sale at the Copelands Marina in Donaghadee in N Ireland.
It was out of the water for a while but is now back in. But am not sure if it was
sold. You could try calling them on 028 91 882184.
As a proud Fastnet 34 owner, I naturally suggest that a Fastnet 34 would be your best choice! ;-)
Please visit my Fastnet 34 website at http://www.bridgecottagepottery.com/fastnet34/index.htm where you can find details on these great boats. It also has a (small at the moment) owners register, including details of one for sale. I think the owner originally wanted a bit more than £20k, but if its still for sale he may have dropped it.
www.fastnet34.com will also get you there, but isnt working to reliably at the moment hence the above web address which works ok.
