Contacted Laurent Giles Naval Architects; turns out this is not a Vertue at all.
Quote: "... but it is certainly not a Laurent Giles Vertue, in fact I very much doubt that it is Laurent Giles. Our Vertue (except for one yacht built in
Italy about 10 years ago) does not have a counter stern but instead a transom stern with transom hung
rudder. Also this yacht in the photograph does have a completely different
keel profile and it seems has a lighter
displacement because the
hull looks to be less full, the overhangs do look disproportional and not as balanced as those on our design."
So there. Thanks for everyone's input. Cheers!
