Bering 50 and Bering 55 are two different models.
Bering 50 "Andjumal" was built in 2007 and no other B50's have been built so far.
Regarding Bering 55 "Mila" she was built in 2008 and now sold to an Australian couple as mentioned above and her new name is "Fonster".
The dimensions on Judy's...
That is not a Bering 55. There is a mistake in the listing. The boat you're talking about listed on Yachtworld by Judy Waldman is the first Bering 50 "Andjumal" which was not advertised too much, since the new Bering 50 design has a lot of improvements.
Regarding the 2013 Bering 60 model "Dzam"...
The Bering 55 listed on Yachtworld is referring to a new built boat.
The photos for the listing are of the first B55, which was sold last year to an Australian couple. They've just completed 3000 Nm from Singapore to Perth, Australia in 3 weeks. They also decided to add a new bimini top to the boat.
