Hello again :-) I have read all your comments with great interest; thank you all for posting! I am going to see the boat again tomorrow armed with my camera and notepad so I shall take the number as suggested, Kevin, and that should give me access to lots more information. The boat is only 45' so it does sound far too big; Ron, let's talk PX when I have seen it and have some pictures :-) Old Goat, you sound wise but I am foolish so I only have myself to blame ;-)
