Not a 435. They only made 4 with the 'Eyebrow' coachroof, here's the last one built in '95. She has 4 hull ports either side and the blue line is below the ports unlike the one in the picture where it goes through the single port
99% sure she's an Oyster 42. The windows look different because you cannot see the bottom detail in your shot due to the angle of heel, plus you're showing one without the sprayhood
