Beneteau is asking for your hull number. They think you are talking about a Moorings version of a Beneteau 50, so they sent me the manual for that. I put it on a link. Click here for it.
(You could also right click and use "Save As".) It's 1.67 meg in size.
If that's not the right manual, then send me your hull number and we'll go from there.
