"how can i know how bad the keel is now, alignment etc etc."
You hire a surveyor to inspect it. Ask around for a recommendation--and preferably someone who doesn't know the dealer.
"When i send the posted picture to jeannou America they disagree that was form a new 2011 boat......very very funny."
Jeanneau says what? That the hull and keel are new and undamaged? And you have that in writing?
If there is concealed damage on the boat, and the dealer says there is no damage, that could be criminal fraud. But you will need to document things. Get a written answer from the dealer, from Jeanneau, and from at least one credentialed surveyor to find out what you have.
Gaps...doesn't mean anything per se. WHy do you say the keel was "fixed" as opposed to perhaps simply being faired, or painted with a different paint than the hull?
