The Nordhavn is a MUCH smaller boat inside, living accommodations wise. Ye olde "compromise" in action...
We have been in company with one of these in fairly nasty conditions, steep, closely spaced quartering 4-6 footers and from looking through the binoculars and talking to them on the radio, it seemed they were doing just fine. Can't say the same for the non-sails-up sail boats and non-stabilized "trawlers" that day. The GH did not have any form of additional stabilization, such as paravanes or hydraulics.
Personally, I don't see it as an ocean crosser either, but for doing the US coast, adjacent islands, Caribbean there is a lot to like about these boats, comfort and operating/maintenance ergonomics wise. Have to add that when we eagerly went on one at a boat show out of curiosity after admiring the above mentioned craft (and the draft!), my wife was disappointed in the fit and finish of the interior. Of course, she'd been living and cruising on a Hatteras for a few years.. ;o).
PS: OP: still trolling? Didn't you say you were buying a 55 foot European wired trawler that you were concerned if your cell phone charger would work in and didn't know how to title it for that matter? What's up with that?
