The Nordhavn 475 will be based on the hull of the Nordhavn 43 but she will be a much different boat, starting with a completely new deck and flybridge. The N475 represents the sleeker, elongated look of modern Nordhavns with the incorporation of an extended cockpit and boat deck, providing not only a more streamlined profile, but also allowing for greater space in the cockpit and more room up top for toys and a bigger tender.
