Thank you very much Andy and Ventsislav for your answers. Andy, everything has been a great help to me, including the photograph of the plate, which I understand from the same sailboat and year that it should also be in the same place of may boat. The problem is that it doesn’t have the plate either, so I can’t know what sailboat number it is because it doesn’t have the purchase invoice either. That for example does not allow me to have a Spanish flag because of the legislation we have here, where the yacht is going to be moored. I only have the Polish and the French but it will be difficult and expensive. So as you say it is a nice sailboat that I like, but I have to decide if I buy a sailboat without this nameplate that leaves me only one possible flag. You have been a great help. Regards.
